        Adobe Font Development Kit for OpenType (AFDKO)
        ===============================================
        
        The AFDKO is a set of tools for building OpenType font files from
        PostScript and TrueType font data.
        
        This repository contains the data files, Python scripts, and sources for
        the command line programs that comprise the AFDKO. The project uses the
        [Apache 2.0 OpenSource license](LICENSE.md).
        
        Please refer to the file [AFDKO-Overview.md](docs/AFDKO-Overview.md)
        for a more detailed description of what is included in the package.
        
        Please see the
        [wiki](https://github.com/adobe-type-tools/afdko/wiki)
        for additional information, such as links to reference materials and related
        projects.
        
        Major Changes
        -------------
        
        The AFDKO has been restructured so that it can be installed as a Python
        package. It now depends on the user\'s Python interpreter, and no longer
        contains its own Python interpreter. In order to do this, two
        Adobe-owned, non-open source programs were dropped: **IS** and
        **checkoutlines**. If these turn out to be sorely missed, an installer
        for them will be added to the old Adobe AFDKO website. The current
        intent is to migrate the many tests in checkoutlines to the newer
        **checkoutlinesufo** (which does work with OpenType and Type 1 fonts,
        but currently does only overlap detection and removal, and a few basic
        path checks).
        
        Installation
        ------------
        
        The AFDKO requires [Python](http://www.python.org/download) 2.7.x. or
        3.6.x.
        
        Releases are available on the [Python Package
        Index](https://pypi.python.org/pypi/afdko) (PyPI) and can be installed
        with [pip](https://pip.pypa.io).
        
        ### Installing
        
        **Option 1 (Recommended)**
        
        - Install [virtualenv](https://virtualenv.pypa.io):
        
                pip install --user virtualenv
        
        - Create a virtual environment:
        
                python -m virtualenv afdko_env
        
        - Activate the virtual environment:
        
            - macOS & Linux
        
                    source afdko_env/bin/activate
        
            - Windows
        
                    afdko_env\Scripts\activate.bat
        
        - Install [afdko](https://pypi.python.org/pypi/afdko):
        
                pip install afdko
        
        Installing the afdko inside a virtual environment prevents conflicts
        between its dependencies and other modules installed globally.
        
        **Option 2**
        
        Install [afdko](https://pypi.python.org/pypi/afdko) globally:
        
            pip install --user afdko
        
        ### Updating
        
        Use the `-U` (or `--upgrade`) option to update the afdko (and its
        dependencies) to the newest stable release:
        
            pip install -U afdko
        
        To get pre-release and in-development versions, use the `--pre` flag:
        
            pip install -U afdko --pre
        
        ### Uninstalling
        
        To remove the afdko package use the command:
        
            pip uninstall afdko
        
        ### Comments
        
        If you have both the FDK from the Adobe AFDKO web page installed, and
        the new afdko package installed, the commands in the new afdko will take
        precedence over commands in the older Adobe FDK, as the Python package
        directory is added at the beginning of the PATH directory list, and the
        old installer added the Adobe FDK directory to the end of the list.
        
        Note that the PyPI installer will add the new adko package paths to the
        start of your system PATH environment variable, and this is not undone
        by the uninstaller. If you want to completely clean up, you will need to
        change the PATH environment variable to remove the new afdko executable
        directories. On the Mac, this means editing the line in your login file
        that sets the PATH variable. On Windows, this means editing the PATH
        environment variable in the System control panel.
        
        You can download older versions of the tools from the [Adobe AFDKO
        homepage](http://www.adobe.com/devnet/opentype/afdko.html). The tools IS
        and checkoutlines are included in these downloads.
        
        Build from Source
        -----------------
        
        In order to build afdko from source get the files from the [afdko github
        repository](https://github.com/adobe-type-tools/afdko), cd to the
        top-level directory of the afdko, and use the `setup.py` script:
        
            python setup.py install
        
        And to be able to run this install command, you must first have
        installed the development tools for your platform.
        
        On the Mac, install these with:
        
            xcode-select --install
        
        On Linux, install these with:
        
            apt-get -y install python2.7
            apt-get -y install python-pip
            apt-get -y install python-dev
        
        On Windows, you need Visual Studio 2017.

        2.6.25 (released 2018-01-26)
        ----------------------------
        
        This release fixes the following issues:
        
        - \[CheckOutlinesUFO\] Skip glyphs whose names are referenced in the
          UFO's lib but do not exist
          ([#228](https://github.com/adobe-type-tools/afdko/issues/228))
        - Partial Python 3 support in `BezTools.py`, `ConvertFontToCID.py`,
          `FDKUtils.py`, `MakeOTF.py`, `StemHist.py`, `autohint.py`,
          `buildMasterOTFs.py` and `ufoTools.py`
          ([#231](https://github.com/adobe-type-tools/afdko/issues/231),
          #232, #233)
        - \[makeotfexe\] Fixed parsing of Character Variant (cvXX) feature
          number
          ([#237](https://github.com/adobe-type-tools/afdko/issues/237))
        - \[pip\] Fixed `pip uninstall afdko`
          ([#241](https://github.com/adobe-type-tools/afdko/issues/241))
        
        2.6.22 (released 2018-01-03)
        ----------------------------
        
        The **afdko** has been restructured so that it can be installed as a
        Python package. It now depends on the user's Python interpreter, and no
        longer contains its own Python interpreter.
        
        In order to do this, the two Adobe-owned, non-opensource programs were
        dropped: `IS` and `checkOutlines`. If these turn out to be sorely
        missed, an installer for them will be added to the old Adobe afdko
        website. The current intent is to migrate the many tests in
        checkOutlines to the newer `checkOutlinesUFO` (which does work with
        OpenType and Type 1 fonts, but currently does only overlap detection and
        removal, and a few basic path checks).

        2.5.66097 (released 2017-12-01)
        -------------------------------
        
        This only lists the major bug fixes since the last release. For a
        complete list see:
        <https://github.com/adobe-type-tools/afdko/commits/master>
        
        - \[buildCFF2VF\] Add version check for fontTools module: only
          starting with version 3.19.0 does fontTools.cffLib build correct
          PrivateDict BlueValues when there are master source fonts not at the
          ends of the axes.
        - \[makeotfexe\] Support mapping a glyph to several Unicode values.
          This can now be done by providing the the UV values as a
          comma-separated list in the third field of the GlyphOrderAndAliasDB
          file, in the 'uniXXXXX' format.
        - \[makeotfexe\] Fixed a crashing bug that can happen when the
          features file contains duplicate class kern pairs. Reported by
          Andreas Seidel in email.
        - \[makeotfexe\] Add fatal messages if a feature file 'cvParameters'
          block is used in anything other than a Character Variant (cvXX)
          feature, or if a 'featureNames' block is used in anything other
          than a Stylistic Set (ssXX) feature.
        - \[makeotfexe\] Relaxed restrictions on name table name IDs. Only 2
          and 6 are now reserved for the implementation.
        - \[makeotfexe\] Fixed bug where use of the 'size' feature in
          conjunction with named stylistic alternates would cause the last
          stylistic alternate name to be replaced by the size feature menu
          name. Incidentally removed old patent notices.
        - \[makeotfexe\] Restored old check for the fatal error of two
          different glyphs being mapped to the same character encoding.
        - \[makeotfexe\] If the last line of a GOADB file did not end in a
          new-line, makeotf quit, saying the line was too long.
        - \[otf2otc\] Can now take a single font as input, and can take an OTC
          font as input.
        - \[sfntdiff\] Fixed old bug: it used to crash if no file path or only
          one file path was provided.
        - \[sfntdiff\] Changed behavior: it now returns non-zero only if a
          real error occurs; it used to return non-zero when there was a
          difference between the fonts.
        - \[spot\] Fixed old bug: a PrivateDict must exist, but it is legal
          for it to have a length of 0.
        - \[tx *et al.*\] Add support for reading and writing blended hints
          from/to CFF2.
        
        2.5.65811 (released 2017-04-27)
        -------------------------------
        
        - \[makeInstancesUFO\] Preserve public.postscriptNames lib key.
        - \[makeInstancesUFO\] Do not use postscriptFontName attribute.
        - \[makeotf\] New option -V to print MakeOTF.py script version.
        - \[tx\] Added new option '-maxs', to set the maximum number of
          subroutines allowed. The default is now 32K, as some legacy systems
          cannot support more than this.
        - \[tx\] Add improved CFF2 support: tx can now use the option -cff2 to
          write from a CFF2 font (in a complete OpenType font) to a file
          containing the output CFF2 table, with full charstring optimization
          and subroutinization. This last option is still work in progress: it
          has not been extensively tested, and does yet support blended hints.
        - \[tx\] Several bug fixes for overlap removal.
        - \[tx\] Fixed bug in subroutinization that could leave a small number
          of unused subroutines in the font. This cleanup is optional, as it
          requires 3x the processing speed with the option than without, and
          typically reduces the font size by less than 0.5 percent.
        - \[ttxn\] Option '-nv' will now print name IDs 3 and 5, but with
          the actual version number replaced by the string "VERSION
          SUPPRESSED".
        - \[ufoTools\] FIx autohint bug with UFO fonts: if edit a glyph and
          re-hint, autohint uses old processed layer glyph.
        
        2.5.65781 (released 2017-04-03)
        -------------------------------
        
        - \[variable fonts\] **buildMasterOTFs** new script to build OTF font
          files from UFO sources, when building variable fonts.
        - \[variable fonts\] **buildCFF2VF** new command to build a CFF2
          variable font from the master OTF fonts.
        - \[autohint\] Fixed bug introduced by typo on Dec 1 2015. Caused
          BlueFuzz to always be set to 1. Rarely causes problems, but found it
          with font that sets BlueFuzz to zero; with BlueFuzz set to 1, some
          of the alignment zones were filtered out as being closer than
          BlueFuzz\*3.
        - \[autohint\] Fixed long-standing bug with UFO fonts where if a glyph
          was edited after being hinted, running autohint would process and
          output only the old version of the glyph from the processed layer.
        - \[CheckOutlinesUFO\] Added "quiet mode" option.
        - \[CheckOutlinesUFO\] Fixed a bug where logic could try and set an
          off-curve point as a start point.
        - \[CheckOutlinesUFO\] Changed the logic for assigning contour order
          and start point. The overlap removal changes both, and
          checkOutlinesUFO makes some attempt to restore the original state
          when possible. These changes will result in different contour order
          and start points than before the change, but fixes a bug, and will
          usually produce the same contour order and start point in fonts that
          are generated as instances from a set of master designs. There will
          always be cases where there will be some differences.
        - \[MakeOTF\] Replace old logic for deriving relative paths with
          python function for the same.
        - \[MakeOTF\] When converting Type 1 to CID in makeotf, the logic in
          mergeFonts and ConvertFontToCID.py was requiring the FDArray
          FontDicts to have keys, like FullName, that are not in fact
          required, and are often not present in the source fonts. Fixed both
          mergeFonts and ConvertFontToCID.py.
        - \[MakeOTF\] By default, makeotf will add a minimal stub DSIG table
          in release mode. The new options '-addDSIG' and '-omitDSIG' will
          force makeotf to either add or omit the stub DSIG table. This
          function was added because the Adobe Type group is discontinuing
          signing font files.
        - \[makeotfexe\] Fixed bug in processing UVS input file for makeotf
          for non-CID fonts.
        - \[makeotfexe\] Fixed bug where makeotf would reject a nameID 25
          record when specified in a feature file. This nameID value used to
          be reserved, but is now used for overriding the postscript family
          named used with arbitrary instances in variable fonts.
        - \[mergeFonts\] Removed requirement for mergeFonts that each FontDict
          have a FullName, Weight, and Family Name. This fixes a bug in using
          mergeFonts with UFO sources and converting to CID-keyed output font.
          Developers should not have to put these fields in the source fonts,
          since they are not required.
        - \[spot\] Fixed bug in name table dump: Microsoft platform language
          tags for Big5 and PRC were swapped.
        - \[stemHist\] Removed debug print line, that caused a lot of annoying
          output, and was left in the last update by accident.
        - \[tx\] When getting Unicode values for output, the presence of UVS
          cmap meant that no UV values were read from any other cmap subtable.
          I fixed this bug, but 'tx' still does not support reading and
          showing UVS values. Doing so will be a significant amount of work,
          so I am deferring that to my next round of FDK work.
        - \[tx\] Added support for CFF2 variable fonts as source fonts: when
          using -t1 or -cff, these will be snapshotted to an instance. If no
          user design vector (UDV) argument is supplied, then the output will
          be the default data. If a UDV argument is supplied with the option
          -U, then the instance is built at the specified point in the design
          space.
        - \[tx\] Added new option +V/-V to remove overlaps in output Type 1
          fonts (mode -t1) and CFF fonts (mode -cff). This is still
          experimental.
        - \[tx\] Made the subroutinizer a lot faster; the speed bump is quite
          noticeable with CJK fonts. (by Ariza Michiharu)
        - \[tx\] Added new option (+V/-V) to remove overlaps. (by Ariza
          Michiharu)
        - \[ttx\] Updated to version 3.9.1 of the fontTools module from master
          branch on GitHub.
        
        2.5.65322 (released 2016-05-27)
        -------------------------------
        
        - \[CMAP files\] Updated UniCNS-UTF32-H to v1.14
        - \[build\] Made changes to allow compiling under Xcode 7.x and OSX
          10.11
        - \[documentation\] Fixed a bunch of errors in the Feature File spec.
          My thanks to Sascha Brawer, who has been reviewing it carefully. See
          the issues at
          <https://github.com/adobe-type-tools/afdko/issues/created_by/brawer>.
        - \[autohint\] Fixed support for history file, which can be used with
          non-UFO fonts only. This has been broken since UFO support was
          added.
        - \[autohintexe\] Fixed really old bug: ascenders and descenders get
          dropped from the alignment zone report if they are a) not in an
          alignment zone and b) there is an overlapping smaller stem hint.
          This happened with a lot of descenders.
        - \[checkOutlines\] Fixed bug in ufoTools.py that kept checkOutlines
          (NOT checkOutlinesUFO) from working with a UFO font.
        - \[checkOutlines\] Fixed bug which misidentified orientation of path
          which is very thin and in part convex. I am a bit concerned about
          the solution, as what I did was to delete some logic that was used
          to double-check the default rules for determining orientation.
          However, the default logic is the standard way to determine
          orientation and should always be correct. The backup logic was
          definitely not always correct as it was applied only to a single
          point, and was correct only if the curve associated with the point
          is concave. It is in fact applied at several different points on a
          path, with the majority vote winning. Since the backup logic is used
          only when a path is very thin, I suspect that it was a sloppy
          solution to fix a specific case. The change was tested with several
          large fonts, and found no false positives.
        - \[makeInstances\] Fixed bug which produced distorted shapes for
          those glyphs which were written with the Type 1 'seac' operator,
          a.k.a. Type 1 composite glyphs.
        - \[makeotfexe\] Fixed bug where using both kern format A and B in a
          single lookup caused random values to be assigned.
        - \[makeotfexe\] Fixed bug where a format A kern value (a single
          value) would be applied to X positioning rather than Y positioning
          for the features 'vkrn'. Applied same logic to vpal, valt, and
          vhal.
        - \[makeotfexe\] Finally integrated Georg Seifert's code for
          supporting hyphen in development glyph names. This version differs
          from Georg's branch in that it does not allow any of the special
          characters in final names (i.e. the left side names in the
          GlyphAliasAndOrderDB). However, allowing this is a smaller tweak
          than it used to be: just use the same arguments in
          `cb.c:gnameFinalScan()` as in `gnameDevScan()`. This update also
          includes Georg's changes for allow source fonts to have CID names
          in the form 'cidNNNN'.
        - \[ConvertToCID\] Fixed bug that the script expected in several
          places that the fontinfo file would contain at least one user
          defined FontDict.
        - \[ConvertToCID\] Fixed bug that the script expected that the source
          font would have Weight and Adobe Copyright fields in the font dict.
        - \[makeotf\] Fixed a bug that kept the '-nS' option for having any
          effect when the '-cn' option is used.
        - \[makeotfexe\] Remove use of 'strsep()'; function is not defined
          in the Windows C library.
        - \[makeotf\] Fixed bug in removing duplicate and conflicting entries.
          Changed logic to leave the first pair defined out of a set of
          duplicate or conflicting entries.
        - \[makeotfexe\] Fixed bug in processing GDEF glyph class statements:
          if multiple GlyphClass statements were used; the additional glyphs
          were added to a new set of 4 glyph classes, rather than merged with
          the allowed 4 glyph classes.
        - \[makeotfexe\] Fixed issue in GDEF definition processing. Made it an
          error to specify both LigCaretByPosition and LigCaretByIndex for a
          glyph.
        - \[makeotfexe\] Corrected error message: language and system
          statements are allowed in named lookups within a feature definition,
          but are not allowed in stand-alone lookups.
        - \[makeotf\] Corrected typo in MakeOTF.py help text about what the
          default source font path.
        - \[makeotfexe\] Fixed an old bug in makeotf. If a mark-to-base or
          mark-to-mark lookup has statements that do not all reference the
          same mark classes, makeotfexe used to write a 'default' anchor
          attachment point of (0.0) for any mark class that was not referenced
          by a given statement. Fixed this bug by reporting a fatal error: the
          feature file must be re-written so that all the statements in a
          lookup must all reference the same set of mark classes.
        - \[makeotf\] Suppressed warning about not using GOADB file when
          building a CID font. Some of the changes I made a few weeks ago to
          allow building fonts with CIDs specified as glyphs names with the
          form 'cidNNNNN' allowed this warning to be be shown, but it is not
          appropriate for CID-keyed fonts.
        - \[makeotf\] Fixed old bug where using option -'cn' to convert a
          non-CID source font to CID would cause a mismatch between the maxp
          table number of glyphs and the number of glyph actually in the output
          font, because the conversion used the source font data rather than
          the first pass name-keyed OTF which had been subject to glyph
          subsetting with the GOADB file.
        - \[makeotf\] Fixed bug in reading UVS files for non\_CID fonts.
        - Fixed copyright statements that are incompatible with the open
          source license. Thanks to Dmitry Smirnov for pointing these out.
          These were in some make files, an example Adobe CMAP file, and some
          of the technical documentation.
        - Fixed typos in help text in ProofPDF.py. Thank you Arno Enslin.
        - \[ttxn\] Fixed bug in ttxn.py that broke it when dumping some
          tables, when used with latest fontTools library.
        - \[tx\] Fixed bug in rounding fractional values when flattening
          library elements, used in design of CJK fonts.
        - \[tx\] Fixed bug in handling FontDict FontMatrix array values: not
          enough precision was used, so that 1/2048 was written as 1/2049 in
          some cases.
        - \[tx\] Fixed bug in reading UFO fonts, so that glyphs with no
          `<outline>` element and with a `<lib>` element would be skipped.
        - \[tx\] Minor code changes to allow 'tx' to compile as a 64 bit
          program.
        - \[tx\] Fixed bug in dumping AFM format data, introduced when tx was
          updated to be 64 bit.
        - \[tx\] Fixed bug in processing seac, introduced in work on rounding
          fractional values.
        - \[tx\] Fixed bug in writing AFM files: -1 value would be written as
          4294967295 instead of -1.
        - \[tx\] Added option -noOpt, renamed blend operator from 'reserved'
          to 'blend'. This was done in order to support experiments with
          multiple master fonts.
        - \[tx\] When reading a UFO font: if it has no Postscript version
          entry, set the version to 1.0.
        - \[tx\] When writing a UFO font: if StemSnap\[H,V\] are missing, but
          Std\[H,V\]W are present, use the Std\[H,V\]W values to supply the
          UFO's postscript StemSnap\[H,V\] values.
        - \[tx\] Fixed old bug with rounding decimal values for BlueScale is
          one of the few Postscript values with several places of decimal
          precision. It is stored as an ASCII text decimal point number in T1,
          T2, and UFO files, but is stored internally as a C 'float' value
          in some programs. Real values in C cannot exactly represent all
          decimal values. For example, the closest that a C 'float' value
          can come to "0.375" is "0.03750000149".When writing output
          fonts, tx was writing out the latter value in ASCII text, rather
          than rounding back to 0.0375. Fixed by rounding to 8 decimal places
          on writing the value out. This bug had no practical consequences, as
          0.0375 and 0.03750000149 both convert to exactly the same float
          value, but was annoying, and could cause rounding differences in any
          programs that use higher precision fields to hold the BlueScale
          value.
        
        2.5.65012 (released 2015-12-01)
        -------------------------------
        
        - \[makeotf\] Fixed bug that kept makeotfexe from building fonts with
          spaces in the path.
        - \[ConvertFontToCID\] Fixed bug that kept makeotf from converting UFO
          fonts to CID.
        - \[makeotf\] Changed support for Unicode Variation Sequence file
          (option '-ci') so that when used with name-keyed fonts, the
          Region-Order field is omitted, and the glyph name may be either a
          final name or developer glyph name. Added warning when glyph in the
          UVS entry is not found in font. See MakeOTF User's Guide.
        - \[makeotfexe\] now always makes a cmap table subtable MS platform,
          Unicode, format 4 for CID fonts. This is required by Windows. If
          there are no BMP Unicode values, then it makes a stub subtable,
          mapping GID 0 to UVS 0.
        - \[tx *et al.*\] When reading a UFO source font, do not complain if
          the fontinfo.plist entry `styleName` is present but has an empty
          string. This is valid, and is common when the style is **Regular**.
        
        2.5.64958 (released 2015-11-22)
        -------------------------------
        
        - \[autohint/tx\] Switched to using new text format that is
          plist-compatible for T1 hint data in UFO fonts. See header of
          ufoTools.py for format.
        - \[autohint\] Finally fixed excessive generation of flex hints. This
          has been an issue for decades, but never got fixed because it did
          not show up anywhere as a problem. The last version of makeotf
          turned on parsing warnings, and so now we notice.
        - \[checkOutlinesUFO\] Fixed bug where abutting paths did not get
          merged if there were no changes in the set of points.
        - \[checkOutlinesUFO\] Fixed bug where a `.glif` file without an
          `<outline>` element was treated as fatal error. It is valid for the
          `<outline>` element to be missing.
        - \[checkOutlines\] Changed -I option so that it also turns off
          checking for tiny paths. Added new option -5 to turn this check back
          on again.
        - \[checkOutlinesUFO\] Increased max number of paths in a glyph from
          64 to 128, per request from a developer.
        - \[CompareFamily\] Fixed old bug in applying ligature width tests for
          CID fonts, and fixed issue with fonts that do not have Mac name
          table names. The logic now reports missing Mac name table names only
          if there actually are some: if there are none, these messages are
          suppressed.
        - \[fontplot/waterfallplot/hintplot/fontsetplot\] Fixed bugs that
          prevented these from being used with CID-keyed fonts and UFO fonts.
          Since the third party library that generates the PDF files is very
          limited, I did this by simply converting the source files to a
          name-keyed Type 1 temporary font file, and then applying the tools
          the temporary file.
        - \[makeInstancesUFO\] Added a call to the ufonormalizer tool for each
          instance. Also added a call to the defcon library to remove all
          private lib keys from lib.py and each glyph in the default layer,
          excepting only "public.glyphOrder".
        - Fixed typos in MakeOTF User Guide reported by Gustavo Ferreira
        - \[MakeOTF\] Increased max number of directories to look upwards when
          searching for GOADB and FontMenuNameDB files from 2 to 3.
        - \[MakeOTF/makeotfexe\] Added three new options:
        
          - `omitMacNames` and `useMacNames` write only Windows platform
            menu names in name table, apart from the names specified in
            the feature file. `useMacNames` writes Mac as well as
            Windows names.
          - `overrideMenuNames` allows feature file name table entries
            to override default values and the values from the
            FontMenuNameDB for name IDs. NameIDs 2 and 6 cannot be
            overridden. Use this with caution, and make sure you have
            provided feature file name table entries for all platforms.
          - `skco`/`nskco` do/do not suppress kern class optimization by
            using left side class 0 for non-zero kern values. Optimizing
            saves a few hundred to thousand bytes, but confuses some
            programs. Optimizing is the default behavior, and previously
            was the only option.
        
        - \[MakeOTF\] Allow building an OTF from a UFO font only. The internal
          `features.fea` file will be used if there is no `features` file in
          the font's parent directory. If the GlyphAliasAndOrderDB file is
          missing, only a warning will be issued. If the FontMenuNameDB is
          missing, makeotf will attempt to build the font menu names from the
          UFO fontinfo file, using the first of the following keys found:
          `openTypeNamePreferredFamilyName`, `familyName`, the family name
          part of the `postScriptName`, and finally the value
          **NoFamilyName**. For style, the keys are:
          `openTypeNamePreferredSubfamilyName`, `styleName`, the style name
          part of the `postScriptName`, and finally the value **Regular**.
        - \[MakeOTF\] Fixed bug where it allowed the input and output file
          paths to be the same.
        - \[makeotfexe\] Extended the set of characters allowed in glyph names
          to include `+ * : ~ ^ !`.
        - \[makeotfexe\] Allow developer glyph names to start with numbers;
          final names must still follow the PS spec.
        - \[makeotfexe\] Fixed crashing bug with more than 32K glyphs in a
          name-keyed font, reported by Gustavo Ferreira.
        - \[makeotfexe\] Merged changes from Khaled Hosny, to remove
          requirement that 'size' feature menu names have Mac platform
          names.
        - \[makeotfexe\] Code maintenance in generation of the feature file
          parser. Rebuilt the 'antler' parser generator to get rid of a
          compile-time warning for zzerraction, and changed featgram.g so that
          it would generate the current featgram.c, rather than having to edit
          the latter directly. Deleted the object files for the 'antler'
          parser generator, and updated the read-me for the parser generator.
        - \[makeotfexe\] Fixed really old bug: relative include file
          references in feature files have not worked right since the FDK
          moved from Mac OS 9 to OSX. They are now relative to the parent
          directory of the including feature file. If that is not found, then
          makeotf tries to apply the reference as relative to the main feature
          file.
        - \[spot\] Fixed bug in dumping stylistic feature names.
        - \[spot\] Fixed bug proofing vertical features: needed to use vkern
          values. Fix contributed by Hiroki Kanou.
        - \[tx *et all.*\] Fix crash when using '-gx' option with source UFO
          fonts.
        - \[tx *et all.*\] Fix crash when a UFO glyph point has a name
          attribute with an empty string.
        - \[tx *et all.*\] Fix crash when a UFO font has no public.glyphOrder
          dict in the lib.plist file.
        - \[tx *et all.*\] Fix really old bug in reading TTF fonts, reported
          by Belleve Invis. TrueType glyphs with nested component references
          and x/y offsets or translation get shifted.
        - \[tx *et all.*\] Added new option '-fdx' to select glyphs by
          excluding all glyphs with the specified FDArray indices. This and
          the '-fd' option now take lists and ranges of indices, as well as
          a single index value.
        - Added a command to call the ufonormalizer tool.
        - Updated to latest version of booleanOperatons, defcon (ufo3 branch),
          fontMath (ufo3 branch), fontTools, mutatorMath, and robofab (ufo3
          branch). The AFDKO no longer contains any private branches of third
          party modules.
        - Rebuilt the Mac OSX, Linux and Windows Python interpreters in the
          AFDKO, bringing the Python version up to 2.7.10. The Python
          interpreters are now built for 64-bit systems, and will not run on
          32-bit systems.
        
        2.5.64700 (released 2015-08-04)
        -------------------------------
        
        - \[ufoTools\] Fixed bug that was harmless but annoying. Every time
          that `autohint -all` was run, it added a new program name entry to
          the history list in the hashmap for each processed glyph. You saw
          this only if you opened the hashmap file with a text editor, and
          perhaps eventually in slightly slower performance.
        - \[checkOutlinesUFO\] Fixed bug where presence of outlines with only
          one or two points caused a stack dump.
        - \[makeotf\] Fixed bug reported by Paul van der Laan: failed to build
          TTF file when the output file name contains spaces.
        - \[spot\] Fixed new bug that caused spot to crash when dumping GPOS
          'size' feature in feature file format.
        
        2.5.64655 (released 2015-07-17)
        -------------------------------
        
        - \[ufoTools\] Fixed bug which placed a new hint block after a flex
          operator, when it should be before.
        - \[autohint\] Fixed new bug in hinting non-UFO fonts, introduced by
          the switch to absolute coordinates in the bez file interchange
          format.
        - \[ufoTools\] Fixed bugs in using hashmap to detect previously hinted
          glyphs.
        - \[ufoTools\] Fixed bugs in handling the issue that
          checkOutlinesUFO.py (which uses the defcon library to write UFO glif
          files) will in some cases write glif files with different file names
          than they had in the default glyph layer.
        - \[makeotf\] Fixed bug with Unicode values in the absolute path to to
          the font home directory.
        - \[makeotf\] Add support for Character Variant (cvXX) feature params.
        - \[makeotf\] Fixed bug where setting Italic style forced OS/2 version
          to be 4.
        - \[spot\] Added support for cvXX feature params.
        - \[spot\] Fixed in crash in dumping long contextual substitution
          strings, such as in 'GentiumPlus-R.TTF'.
        - \[tx\] Fixed bug in handling CID glyph ID greater than 32K.
        - \[tx\] Changed to write widths and FontBBox as integer values.
        - \[tx\] Changed to write SVG, UFO, and dump coordinates with 2 places
          of precision when there is a fractional part.
        - \[tx\] Fixed bugs in handling the '-gx' option to exclude glyphs.
          Fixed problem with CID \> 32K. Fixed problem when font has 65536
          glyphs: all glyphs after first last would be excluded.
        - \[tx\] Fixed rounding errors in writing out decimal values to cff
          and t1 fonts.
        - \[tx\] Increased interpreter stack depth to allow for CUBE operators
          (Library elements) with up to 9 blend axes.
        - Fixed Windows builds: had to provide a roundf() function, and more
          includes for the \_tmpFile function. Fixed a few compile errors.
        - Fixed bug in documentation for makeInstancesUFO.
        - Fixed bug in BezTools.py on Windows, when having to use a temp file.
        
        2.5.64261 (released 2015-05-26)
        -------------------------------
        
        - \[autohintexe\] Worked through a lot of problems with fractional
          coordinates. In the previous release, autohintexe was changed to
          read and write fractional values. However, internal value storage
          used a Fixed format with only 7 bits of precision for the value.
          This meant that underflow errors occurred with 2 decimal places,
          leading to incorrect coordinates. I was able to fix this by changing
          the code to use 8 bits of precision, which supports 2 decimal places
          (but not more!) without rounding errors, but this required many
          changes. The current autohint output will match the output of the
          previous version for integer input values, with two exceptions.
          Fractional stem values will (rarely) differ in the second decimal
          place. The new version will also choose different hints in glyphs
          which have coordinate values outside of the range -16256 to +16256;
          the previous version had a bug in calculating weights for stems.
        - \[autohint\] Changed logic for writing bez files to write absolute
          coordinate values instead of relative coordinate values. Fixed bug
          where truncation of decimal values lead to cumulative errors in
          positions adding up to more than 1 design unit over the length of a
          path.
        - \[tx\] Fixed bugs in handling fractional values: `tx` had a bug with
          writing fractional values that are very near an integer value for
          the modes -dump, -svg, and -ufo. `tx` also always applied the logic
          for applying a user transform matrix, even though the default
          transform is the identity transform. This has the side-effect of
          rounding to integer values.
        
        2.5.64043 (released 2015-04-08)
        -------------------------------
        
        - \[checkOutlinesUFO\] Added new logic to delete any glyphs from the
          processed layer which are not in the 'glyphs' layer.
        - \[makeotf\] When building CID font, some error messages were printed
          twice.
        - \[makeotf\] Added new option `stubCmap4`. This causes makeotf to
          build only a stub cmap 4 subtable, with just two segments. Needed
          only for special cases like AdobeBlank, where every byte is an
          issue. Windows requires a cmap format 4 subtable, but not that it be
          useful.
        - \[makeCIDFont\] Output FontDict was sized incorrectly. A function at
          the end adds some FontInfo keys, but did not increment the size of
          the dict. Legacy logic is to make the FontInfo dict be 3 larger than
          the current number of keys.
        - \[makeInstanceUFO\] Changed AFDKO's branch of mutatorMath so that
          kern values, glyph widths, and the BlueValues family of global hint
          values are all rounded to integer even when the `decimal` option is
          used.
        - \[makeInstanceUFO\] Now deletes the default 'glyphs' layer of the
          target instance font before generating the instance. This solves the
          problem that when glyphs are removed from the master instances, the
          instance font still has them.
        - \[makeInstanceUFO\] Added a new logic to delete any glyphs from the
          processed layer which are not in the 'glyphs' layer.
        - \[makeInstanceUFO\] Removed the `all` option: even though
          mutatorMath rewrites all the glyphs, the hash values are still valid
          for glyphs which have not been edited. This means that if the
          developer edits only a few glyphs in the master designs, only those
          glyphs in the instances will get processed by checkOutlinesUFO and
          autohint.
        - Support fractional coordinate values in UFO workflow:
        
          - checkOutlinesUFO (but not checkOutlines), autohint, and
            makeInstancesUFO will now all pass through decimal
            coordinates without rounding, if you use the new option
            "decimal". tx will dump decimal values with 3 decimal
            places.
          - tx already reported fractional values, but needed to be
            modified to report only 3 decimal places when writing UFO
            glif files, and in PDF output mode: Acrobat will not read
            PDF files with 9 decimal places in position values.
          - This allows a developer to use a much higher precision of
            point positioning without using a larger em-square. The
            Adobe Type group found that using an em-square of other than
            1000 design units still causes problems in layout and text
            selection line height in many apps, despite it being legal
            by the Type 1 and CFF specifications.
          - Note that code design issues in autohint currently limit the
            decimal precision and accuracy to 2 decimal places: 1.01
            works but 1.001 will be rounded to 0.
        
        2.5.63782 (released 2015-03-03)
        -------------------------------
        
        - \[tx\] Fix bug in reading TTFs. Font version was taken from the name
          table, which can include a good deal more than just the font
          version. Changed to read fontRevision from the head table.
        - \[detype1\] Changed to wrap line only after an operator name, so
          that the coordinates for a command and the command name would stay
          on one line.
        - \[otf2otc\] Pad table data with zeros so as to align tables on a 4
          boundary. Submitted by Cosimo Lupo.
        
        2.5.63718 (released 2015-02-21)
        -------------------------------
        
        - \[ufoTools\] Fixed a bug with processing flex hints that caused
          outline distortion.
        - \[compareFamily\] Fixed bug in processing hints: it would miss
          fractional hints, and so falsely report a glyph as having no hints.
        - \[compareFamily\] Support processing CFF font without a FullName
          key.
        - \[checkOutlinesUFO\] Coordinates are written as integers, as well as
          being rounded.
        - \[checkOutlinesUFO\] Changed save function so that only the
          processed glyph layer is saved, and the default layer is not
          touched.
        - \[checkOutlinesUFO\] Changed so that XML type is written as
          'UTF-8' rather than 'utf-8'. This was actually a change in the
          FontTools xmlWriter.py module.
        - \[checkOutlinesUFO\] Fixed typos in usage and help text.
        - \[checkOutlinesUFO\] Fixed hash dictionary handling so that it will
          work with autohint, when skipping already processed glyphs.
        - \[checkOutlinesUFO\] Fixed false report of overlap removal when only
          change was removing flat curve
        - \[checkOutlinesUFO\] Fixed stack dump when new glyph is seen which
          is not in hash map of previously processed glyphs.
        - \[checkOutlinesUFO\] Added logic to make a reasonable effort to sort
          the new glyph contours in the same order as the source glyph
          contours, so the final contour order will not depend on (x,y)
          position. This was needed because the pyClipper library (which is
          used to remove overlaps) otherwise sorts the contours in (x,y)
          position order, which can result in different contour order in
          different instance fonts from the same set of master fonts.
        - \[makeInstancesUFO\] Changed so that the option -i (selection of
          which instances to build) actually works.
        - \[makeInstancesUFO\] Removed dependency on the presence of
          instance.txt file.
        - \[makeInstancesUFO\] Changed to call checkOutlinesUFO rather than
          checkOutlines
        - \[makeInstancesUFO\] Removed hack of converting all file paths to
          absolute file paths: this was a work-around for a bug in
          robofab-ufo3k that is now fixed.
        - \[makeInstancesUFO\] Removed all references to old instances.txt
          meta data file.
        - \[makeInstancesUFO\] Fixed so that current dir does not have to be
          the parent dir of the design space file.
        - Merged fixes from the GitHub AFDKO open source repo.
        - Updated to latest version defcon, fontMath, robofab, and
          mutatorMath.
        - Fix for Yosemite (Mac OSX 10.10) in FDK/Tools/setFDKPaths. When an
          AFDKO script is ran from another Python interpreter, such as the one
          in RoboFont, the parent Python interpreter may set the Unix
          environment variables PYTHONHOME and PYTHONPATH. This can cause the
          AFDKO Python interpreter to load some modules from its own library,
          and others from the parent interpreters library. If these are
          incompatible, a crash ensues. The fix is to unset the variables
          PYTHONHOME and PYTHONPATH before the AFDKO interpreter is called.
          Note: As a separate issue, under Mac OSX 10.10, Python calls to FDK
          commands will only work if the calling app is run from the
          command-line (e.g: `open /Applications/RoboFont.app`), and the
          argument `shell="True"` is added to the subprocess module call to
          open a system command. I favor also adding the argument
          `stderr=subprocess.STDOUT`, else you will not see error messages
          from the Unix shell. Example:
          `log = subprocess.check_output( "makeotf -u", stderr=subprocess.STDOUT, shell=True)`.
        
        2.5.63408 (released 2014-12-02)
        -------------------------------
        
        - \[spot\] Fixed error message in GSUB chain contextual 3 proof file
          output; was adding it as a shell comment to the proof output,
          causing conversion to PDF to fail.
        - \[makeotf\] Increased the limit for glyph name length from 31 to 63
          characters. This is not encouraged in shipping fonts, as there may
          be text engines that will not accept glyphs with more than 31
          characters. This was done to allow building test fonts to look for
          such cases.
        
        2.5.63209 (released 2014-09-18)
        -------------------------------
        
        - \[makeInstancesUFO\] Added new script to build instance fonts from
          UFO master design fonts. This uses the design space XML file
          exported by Superpolator 3 in order to define the design space, and
          the location of the masters and instance fonts in the design space.
          The definition of the format of this file, and the library to use
          the design space file data, is in the open source mutatorMath
          library on GitHub, and maintained by Erik van Blokland. There are
          several advantages of the Superpolator design space over the
          previous **makeInstances** script, which uses the Type 1 Multiple
          Master font format to hold the master designs. The new version a)
          allows different master designs and locations for each glyph, and b)
          allows master designs to be arbitrarily placed in the design space,
          and hence allows intermediate masters. In order to use the
          mutatorMath library, the AFDKO-supplied Python now contains the
          robofab, fontMath, and defcon libraries, as well as mutatorMath.
        - \[ttx\] Updated to the latest branch of the fontTools library as
          maintained by Behdad Esfahbod on GitHub. Added a patch to cffLib.py
          to fix a minor problem with choosing charset format with large glyph
          sets.
        - Updated four Adobe-CNS1-\* ordering files.
        
        2.5.63164 (released 2014-09-08)
        -------------------------------
        
        - \[makeotf\] Now detects `IsOS/2WidthWeightSlopeOnly` as well as the
          misspelled `IsOS/2WidthWeigthSlopeOnly`, when processing the
          fontinfo file.
        - \[makeotfexe\] Changed behavior when 'subtable' keyword is used in
          a lookup other than class kerning. This condition now triggers only
          a warning, not a fatal error. Change requested by FontForge
          developers.
        - \[makeotf\] Fixed bug which prevented making TTF fonts under
          Windows. This was a problem in quoting paths used with the 'ttx'
          program.
        - Fixed installation issues: removed old Windows install files from
          the Windows AFDKOPython directory. This was causing installation of
          a new AFDKO version under Windows to fail when the user's PATH
          environment variable contained the path to the AFDKOPython
          directory. Also fixed command file for invoking ttx.py.
        - Updated files used for building ideographic fonts with Unicode IVS
          sequences:
          `FDK/Tools/SharedData/Adobe Cmaps/Adobe-CNS1/Adobe-CNS1_sequences.txt`
          and `Adobe-Korea1_sequences.txt`.
        
        2.5.62754 (released 2014-05-14)
        -------------------------------
        
        - \[IS/addGlobalColor\] When using the '-bc' option, fixed bug with
          overflow for CID value in dumping glyph header. Fixed bug in IS to
          avoid crash when logic for glyphs \> 72 points is used.
        - \[makeotfexe\] Fixed bug that applied '-gs' option as default
          behavior, subsetting the source font to the list of glyphs in the
          GOADB.
        
        2.5.62690 (released 2014-04-30)
        -------------------------------
        
        - \[makeotf\] When building output TTF font from an input TTF font,
          will now suppress warnings that hints are missing. Added a new
          option '-shw' to suppress these warnings for other fonts that with
          unhinted glyphs. These warnings are shown only when the font is
          built in release mode.
        - \[makeotfexe\] If the cmap format 4 UTF16 subtable is too large to
          write, then makeotfexe writes a stub subtable with just the first
          two segments. The last two versions allowed using '-' in glyph
          names. Removed this, as it breaks using glyph tag ranges in feature
          files.
        - Updated copyright, and removed patent references. Made extensive
          changes to the source code tree and build process, to make it easier
          to build the open source AFDKO. Unfortunately, the source code for
          the **IS** and **checkOutlines** programs cannot be open sourced.
        - \[tx/mergeFonts/rotateFont\] Removed '-bc' option support, as
          this includes patents that cannot be shared in open source.
        - \[tx\] All tx-related tools now report when a font exceeds the max
          allowed subroutine recursion depth.
        - \[tx/mergeFonts/rotateFont\] Added common options to all when
          possible: all now support UFO and SVG fonts, the '-gx' option to
          exclude fonts, the '-std' option for cff output, and the '-b'
          option for cff output.
        
        2.5.61944 (released 2014-04-05)
        -------------------------------
        
        - \[makeotf\] Added new option '-gs'. If the '-ga' or '-r'
          option is used, then '-gs' will omit from the font any glyphs
          which are not named in the GOADB file.
        - \[Linux\] Replaced the previous build (which worked only on 64-bit
          systems) with a 32 bit version, and rebuilt checkOutlines with debug
          messages turned off.
        - \[ttx\] Fixed FDK/Tools/win/ttx.cmd file so that the 'ttx' command
          works again.
        
        2.5.61911 (released 2014-03-25)
        -------------------------------
        
        - \[makeotf\] Add support for two new 'features' file keywords, for
          the OS/2 table. Specifying 'LowerOpSize' and 'UpperOpSize' now
          sets the values 'usLowerOpticalPointSize' and
          'usUpperOpticalPointSize' in the OS/2 table, and set the table
          version to 5.
        - \[makeotf\] Fixed the '-newNameID4' option so that if the style
          name is "Regular", it is omitted for the Windows platform name ID
          4, as well as in the Mac platform version. See change in
          build 61250.
        - \[tx\] When the user does not specify an output destination file
          path (in which case tx tries to write to stdout), tx now reports a
          fatal error if the output is a UFO font, rather than crashing.
        - \[tx\] Fixed crash when encountering an empty `<dict/>` XML
          element.
        - \[spot\] Added logic to dump the new fields in OS/2 table version 5,
          **usLowerOpticalPointSize** and **usUpperOpticalPointSize**. An
          example of these values can be seen in the Windows 8 system font
          Sitka.TTC.
        - \[ufo workflow\] Fixed autohint and checkOutlines so that the '-o'
          option works, by copying the source UFO font to the destination UFO
          font name, and then running the program on the destination UFO font.
        - \[ufo workflow\] Fixed tools that the PostScript font name is not
          required.
        - Added Linux build.
        
        2.5.61250 (released 2014-02-17)
        -------------------------------
        
        - \[tx\] Fixed rare crashing bug in reading a font file, where a
          charstring ends exactly on a refill buffer boundary.
        - \[tx\] Fixed rare crashing bug in subroutinization.
        - \[tx\] Fixed bug where it reported values for wrong glyph with more
          than 32K glyphs in the font.
        - \[tx\] Fixed bug where the tool would not dump a TrueType Collection
          font file that contained OpenType/CFF fonts.
        - \[tx\] Fixed issue where it failed to read a UFO font if the UFO
          font lacked a fontinfo.plist file, or a psFontName entry.
        - \[IS\] Fixed IS so that it no longer scales the fontDict FontMatrix,
          when a scale factor is supplied, unless you provide an argument to
          request this.
        - \[makeotf\] The option '-newNameID4' now builds both Mac and Win
          name ID 4 using name ID 1 and 2, as specified in the OpenType spec.
          The style name is omitted from name ID 4 it is "Regular".
        - \[makeotf\] Changed logic for specifying ValueFormat for PosPair
          value records. Previous logic always used the minimum ValueFormat.
          Since changing ValueFormat between one PosPair record and the next
          requires starting a new subtable, feature files that used more than
          one position adjustment in a PosPair value record often got more
          subtable breaks then necessary, especially when specifying a PairPos
          statement with an all zero Value Record value after a PairPos
          statement with a non-zero Value Record. With the new logic, if the
          minimum ValueFormat for the new ValueRecord is different than the
          ValueFormat used with the ValueRecord for the previous PairPos
          statement, and the previous ValueFormat permits expressing all the
          values in the current ValueRecord, then the previous ValueFormat is
          used for the new ValueRecord.
        - Added commands **otc2otf** and **otf2otc** to build OpenType
          collection files from a OpenType font files, and vice-versa.
        - \[ttx\] Updated the FontTools library to the latest build on the
          GitHub branch maintained by Behdad Esfahbod, as of Jan 14 2014.
        - \[ufo workflow\] Fixed bugs in ufoTools.py. The glyph list was being
          returned in alphabetic order, even when the public.glyphOrder key
          was present in lib.py. Failed when the glyphOrder key was missing.
        
        2.5.60908 (released 2013-10-21)
        -------------------------------
        
        - \[tx\] Can now take UFO font as a source font file for all outputs
          except rasterization. It prefers GLIF file from the layer
          `glyphs.com.adobe.type.processedGlyphs`. You can select another
          preferred layer with the option '-altLayer `<layer name>`'. Use
          'None' for the layer name in order to have tx ignore the preferred
          layer and read GLIF files only from the default layer.
        - \[tx\] Can now write to a UFO with the option '-ufo'. Note that it
          is NOT a full UFO writer. It writes only the information from the
          Postscript font data. If the source is an OTF or TTF font, it will
          not copy any of the meta data from outside the font program table.
          Also, if the destination is an already existing UFO font, tx will
          overwrite it with the new data: it will not merge the new font data
          with the old.
        - \[tx\] Fixed bugs with CID values \> 32K: used to write these as
          negative numbers when dumping to text formats such as AFM.
        - \[autohint/checkOutlines\] These programs can now be used with UFO
          fonts. When the source is a UFO font, the option '-o' to write to
          another font is not permitted. The changed GLIF files are written to
          the layer 'glyphs.com.adobe.type.processedGlyphs'. Each script
          maintains a hash of the width and marking path operators in order to
          be able to tell if the glyph data in the default layer has changed
          since the script was last run. This allows the scripts to process
          only those glyphs which have changed since the last run. The first
          run of autohint can take two minutes for a 2000 glyph font; the
          second run takes less then a second, as it does not need to process
          the unchanged glyphs.
        - \[stemHist/makeotf\] Can now take UFO fonts as source fonts.
        
        2.5.60418 (released 2013-02-26)
        -------------------------------
        
        - \[autohint\] Now skips comment lines in fontinfo file.
        - \[makeotf\] Added support for source font files in the 'detype1'
          plain text format. Added logic for "Language" keyword in fontinfo
          file; if present, will attempt to set the CID font makeotf option
          -"cs" to set he Mac script value.
        - \[compareFamily\] Added check in Family Test 10 that font really is
          monospaced or not when either the FontDict isFixedPitch value or the
          Panose value says that it is monospaced.
        - \[spot\] Fixed bug that kept 'palt'/'vpal' features from being
          applied when proofing kerning.
        
        2.5.59149 (released 2012-10-31)
        -------------------------------
        
        - \[makeotf\] When building OpenType/TTF files, changed logic to copy
          the OS/2 table usWinAscent/Descent values over the head table
          yMax/yMin values, if different. This was because:
        
          - both pairs are supposed to represent the real font bounding box
            top and bottom,and should be equal;
          - the TTF fonts we use as sources for makeotf are built by FontLab;
          - FontLab defines the font bounding box for TrueType fonts by using
            off-curve points as well as on-curve points. If a path does not have
            on-curve points at the top and bottom extremes, the font bounding
            box will end up too large. The OS/2 table usWinAscent/Descent
            values, however, are set by makeotf using the converted T1 paths,
            and are more accurate. Note that I do not try to fix the head table
            xMin and xMax. These are much less important, as the head table yMin
            and yMax values are used for line layout by many apps on the Mac,
            and I know of no application for the xMin and yMin values.
        
        - \[makeotf\] Changed default Unicode H CMAP file for Adobe-Japan1 CID
          fonts to use the UniJIS2004-UTF32-H file.
        - Added the CID font vertical layout files used with KozMinPr6N and
          KozGoPr6N: AJ16-J16.VertLayout.KozGo and AJ16-J16.VertLayout.KozMin.
        - Updated several Unicode CMAP files, used only with CID fonts.
        - Added new Perl script, glyph-list.pl, used in building CID fonts.
          This replaces the three scripts extract-cids.pl, extract-gids.pl,
          and extract-names.pl, which have been removed from the AFDKO.
        
        2.5.58807 (released 2012-09-13)
        -------------------------------
        
        - \[makeotf\] Discovered that when building TTF fonts, the GDEF table
          was not being copied to the final TTF font file. Fixed.
        
        2.5.58732 (released 2012-09-04)
        -------------------------------
        
        - \[autohint\] Added new feature to support sets of glyphs with
          different baselines. You can now specify several different sets of
          global alignment zones and stem widths, and apply them to particular
          sets of glyphs within a font when hinting. See option '-hfd' for
          documentation.
        - \[autohint\] Allow AC to handle fonts with no BlueValues, aka
          alignment zones.
        - \[autohint\] Respect BlueFuzz value in font.
        - \[autohint\] Fixed the options to suppress hint substitution and to
          allow changes.
        - \[autohint\] When hinting a font with no alignment zones or invalid
          alignment zones (and with the '-nb' option), set the arbitrary
          alignment zone outside the FontBBox, rather than the em-square.
        - \[checkOutlines\] Fixed bug where the arms of an X would be falsely
          identified as coincident paths, when they are formed by only two
          paths with identical bounding boxes.
        - \[checkOutlines\] Fixed bug where very thin elements would get
          identified as a tiny sub path, and get deleted.
        - \[checkOutlines\] Fixed bug in determining path orientation. Logic
          was just following the on-path points, and could get confused by
          narrow concave inner paths, like parentheses with an inner contour
          following the outer contour, as in the Cheltenham Std HandTooled
          faces.
        - \[checkOutlines\] Fixed bugs in determining path orientation.
          Previous logic did not handle multiple inner paths, or multiple
          contained outer paths. Logic was also dependent on correctly sorting
          paths by max Y of path bounding box. Replaced approximations with
          real bezier math to determine path bounding box accurately.
        - \[checkOutlines\] Changed test for suspiciously large bounding box
          for an outline. Previous test checked for glyph bounding box outside
          of fixed limits that were based on a 1000 em square. The new test
          looks only for paths that are entirely outside a rectangle based on
          the font's em square, and only reports them: it does not ever
          delete them. Added new option '-b' to set the size of the design
          square used for the test.
        - \[checkOutlines\] Fixed bug where it would leave a temp file on disk
          when processing a Type 1 font.
        - \[checkOutlines\] Removed test for coincident control points. This
          has not been an issue for decades. It is frequently found in fonts
          because designers may choose to not use one of the two control
          points on a curve. The unused control point then has the same
          coordinates as its nearest end-point, and would to cause
          checkOutlines to complain.
        - \[compareFamily\] Single Test 6. Report error if there is a patent
          number in the copyright. Adobe discovered that a company can be sued
          if it ships any product with an expired patent number.
        - \[compareFamily\] Single Test 22 (check RSB and LSB of ligature vs.
          the left and right ligature components) did not parse contextual
          ligature substitution rules correctly. Now fixed.
        - \[compareFamily\] Family Test 18. Survive OTF fonts with no blue
          values.
        - \[compareFamily\] Family Test 2 (Check that the Compatible Family
          group has same nameIDs in all languages): Added the WPF nameIDs 21
          and 22 to the exception list, which may not exist in all faces of a
          family.
        - \[fontsetplot\] Fixed so it works with CID fonts. Also fixed so that
          widow line control works right. Added new low level option for
          controlling point size of group header.
        - \[fontsetplot\] Fixed syntax of assert statements. Produced error
          messages on first use of the \*plot commands.
        - \[kernCheck\] Fix so that it survives fonts with contextual kerning.
          It does not, however, process the kern pairs in contextual kerning.
        - \[makeotf\] Fixed bug in mark to ligature. You can now use an
          `<anchor NULL>` element without having to follow it by a dummy mark
          class reference.
        - \[makeotf\] Fixed bug which limited source CID fonts to a maximum of
          254 FDArray elements, rather than the limit of 255 FDArray elements
          that is imposed by the CFF spec.
        - \[makeotf\] Fixed bugs in automatic GDEF generation. When now GDEF
          is defined, all conflicting class assignments in the GlyphClass are
          filtered out. If a glyph is assigned to a make class, that
          assignment overrides any other class assignment. Otherwise, the
          first assignment encountered will override a later assignment. For
          example, since the BASE class is assigned first, assignment to the
          BASE class will override later assignments to LIGATURE or COMPONENT
          classes.
        - \[makeotf\] Fix bug in validating GDEF mark attachment rules. This
          now validates the rules, rather than random memory. Had now effect
          on the output font, but did sometimes produce spurious error
          messages.
        - \[makeotf\] Fix crashing bug when trying to report that a glyph
          being added to a mark class is already in the mark class.
        - \[makeotf\] If the OS/2 code page bit 29 (Macintosh encoding) is
          set, then also set bit 0 (Latin (1252). Under Windows XP and Windows
          7, if only the Mac bit is set, then the font is treated as having no
          encoding, and you cannot apply the font to even basic Latin text.
        - \[makeotf\] By default, set Windows name ID 4 (Full Name) same as
          Mac nameID 4, instead of setting it to the PostScript name. This is
          in order to match the current definition of the name ID 4 in the
          latest OpenType spec. A new option to makeotf ('-useOldNameID4'),
          and a new key in the fontinfo file ("UseOldNameID4"), will cause
          makeotf to still write the PS name to Windows name ID 4.
        - \[makeotf\] Add support for WPF names, name ID 21 and 22.
        - \[makeotf\] Fixed attachment order of marks to bug in generating
          Mark to Ligature (GPOS lookup type 4). The component glyphs could be
          reversed.
        - \[makeotf\] Fixed bug in auto-generating GDEF table when Mark to
          Mark (GPOS lookup Type 4) feature statements are used. The target
          mark glyphs were registered as both GDEF GlyphClass Base and Mark
          glyphs, and the former took precedence. makeotfexe now emits a
          warning when a glyph gets assigned to more than one class when
          auto-generating a GDEF table GlyphClass, and glyphs named in mark to
          mark lookups are assigned only to the Mark GDEF glyph class.
        - \[makeotf\] Fixed bugs in generating TTF fonts from TTF input. It
          now merges data from the head and hhea tables, and does a better job
          of dealing with the 'post' table. The previous logic made
          incorrect glyph names when the glyphs with names from the Mac Std
          Encoding were not all contiguous and at the start of the font.
        - \[makeotf\] Added new option '-cn' for non-CID source fonts, to
          allow reading multiple global font alignment zones and stem widths
          from the fontinfo file, and using this to build a CID-keyed CFF
          table with an identity CMAP. This is experimental only; such fonts
          may not work in many apps.
        - \[makeotf\] Fixed bug where the coverage table for an element in the
          match string for a chaining contextual statement could have
          duplicate glyphs. This happens when a glyph is specified more than
          once in the class definition for the element. The result is that the
          format 2 coverage table has successive ranges that overlap: the end
          of one range is the same glyph ID as the start of the next range;
          harmless, but triggers complaints in font validators.
        - \[makeotf\] Updated to latest Adobe CMAP files for ideographic
          fonts. Changed name of CMAP directories in the AFDKO, and logic for
          finding the files.
        - \[makeotf\] When providing a GDEF feature file definition, class
          assignments now may be empty:
        
                table GDEF {
                    GlyphClassDef ,,,;
                } GDEF;
        
          is a valid statement. You just need to provide all three commas and
          the final colon to define the four classes. The following statement
          builds a GDEF GlyphClass with an empty Components class.
        
                table GDEF {
                    GlyphClassDef [B], [L], [M], ;
                } GDEF;
        
        - \[makeotf\] The glyph alias file now defines order in which glyphs
          are added to the end of the target font, as well as defining the
          subset and renaming.
        - \[makeotf\] The `-cid <cidfontinfo>` option for converting a
          font to CID can now be used without a glyph alias file, if the
          source font glyphs have names in the form "cidXXXX", as is output
          when mergeFonts is used to convert from CID to name-keyed. If the
          `-cid <cidfontinfo>` option is used, and there is no glyph alias
          file, then any glyphs in the font without a name in the form
          "cidXXXX" will be ignored.
        - \[spot\] Added error message for duplicate glyph IDs in coverage
          tables with format 2, a problem caused by a bug in makeotf with some
          Adobe fonts that use chaining contextual substitution. Note: error
          message is written only if level 7 GSUB/GPOS dump is requested.
        - \[spot\] Minor formatting changes to the GSUB/GPOS level 7 dump, to
          make it easier to edit this into a real feature file.
        - \[spot\] When writing out feature file syntax for GPOS 'ignore
          pos' rules, the rule name is now written as 'ignore pos', not
          just 'ignore'.
        - \[spot\] Can now output glyph names up to 128 chars (Note: these are
          not legal PostScript glyph names, and should be encountered only in
          development fonts.)
        - \[spot\] Has new option '-ngid' which suppresses output of the
          trailing glyph ID `@<gid>` for TTF fonts.
        - \[spot\] No longer dumps the DefaultLangSys entry when there is
          none.
        - \[spot\] Changed dump logic for contextual and chain contextual
          lookups so that spot will not dump the lookups referenced by the
          substitution or position rules in the contextual lookups. The
          previous logic led to some lookups getting dumped many times, and
          also to infinite loops in cases where a contextual lookup referenced
          other contextual lookups.
        - \[spot\] Added support for Apple kern subtable format 3. Fixed old
          bug causing crash when dumping font with Apple kern table from
          Windows OS.
        - \[spot\] Fixed error when dumping Apple kern table subtable format
          0, when kern table is at end of font file.
        - \[spot\] Fixed crashing bug seen in DejaVuSansMono.TTF: spot did not
          expect an anchor offset to be zero in a Base Array base Record.
        - \[spot\] Removed comma from lookupflag dump, to match feature file
          spec.
        - \[spot\] Added logic to support name table format 1, but it probably
          does not work, since I have been unable to find a font to test with
          this format.
        - \[spot\] Fixed spelling error for "Canadian" in OS/2 code page
          fields.
        - \[spot\] Changed dump of cmap subtable 14: hex values are
          uppercased, and base+UVS values are written in the order \[base,
          uvs\].
        - \[stemHist\] Always set the alignment zones outside the font BBox,
          so as to avoid having the source font alignment zones affect
          collection of stem widths.
        - \[stemHist\] Fix bug where the glyph names reported in the stem and
          alignment reports were off by 1 GID if the list of glyphs included
          the '.notdef' glyph.
        - \[tx\] Added support for option '-n' to remove hints for writing
          Type 1 and CFF output fonts.
        - \[tx\] Added new option "+b" to the cff output mode, to force
          glyph order in the output font to be the same as in the input font.
        - \[tx\] Fixed bug in flattening 'seac' operator. If the glyph
          components were not in the first 256 glyphs, then the wrong glyph
          would be selected.
        - \[tx\] Added new library to read in svg fonts as a source. tx can
          now read all the SVG formats that it can write. Handles only the
          path operators: M, m, L, L, C, c, Z, z, and the font and glyph
          attributes: 'font-family', 'unicode', 'horiz-adv-x',
          'glyph-name', 'missing-glyph'.
        - \[tx\] Fixed bug in converting TTF to OpenType/CFF. It flipped the
          sign of the ItalicAngle in the 'post' table, which in turn flipped
          the sign of the OS/2 table fields ySubscriptXOffset and
          ySuperscriptXOffset. This bug showed up in TTF fonts built by
          makeotf, as makeotf uses 'tx' to build a temporary Type 1 font
          from the source TTF.
        - \[tx\] Fixed bug where '-usefd' option was not respected, when
          converting from CID to name-keyed fonts.
        - Updated the internal Python interpreter to version 2.7.
        - Updated Adobe Cmaps/Adobe-Japan1 files:
        
          - Adobe-Japan1\_sequences.txt
          - UniJIS-UTF32-H
          - UniJIS2004-UTF32-H
          - UniJISX0213-UTF32-H
          - UniJISX02132004-UTF32-H
        
        - Added several scripts related to CID font production:
        
          - cmap-tool.pl
          - extract-cids.pl
          - extract-gids.pl
          - extract-names.pl
          - fdarray-check.pl
          - fix-fontbbox.pl
          - hintcidfont.pl
          - subr-check.pl
        
        2.5.25466 (released 2012-03-04)
        -------------------------------
        
        - \[charplot\] This was non-functional since build 21898. Now fixed.
        - \[checkOutlines\] Changed so that the test for nearly vertical or
          horizontal lines is invoked only if the user specifies the options
          '-i' or '-4', instead of always. It turns out that this test,
          when fixed automatically, causes more problems than it cures in CJK
          fonts.
        - \[compareFamily\] Changed so that the default is to check stem
          widths and positions for bogus hints. Used 'tx' rather than Python
          code for parsing charstring in order to speed up hint check.
        - \[compareFamily\] Updated script tags and language tags according to
          OpenType specification version 1.6.
        - \[documentation\] In feature file syntax reference, fixed some
          errors and bumped the document version to 1.10.
        - \[documentation\] Fixed typo in example in section 4.d: lookFlag
          values are separated by spaces, not commas.
        - \[documentation\] Fixed typo in example in section 8.c on stylistic
          names: quotes around name string need to be matching double quotes.
          Reported by Karsten Luecke.
        - \[documentation\] Changed agfln.txt copyright notice to BSD license.
        - \[makeInstances\] Fixed bug where a space character in any of the
          path arguments caused it to fail.
        - \[makeInstances\] Fixed bug that can make the FontBBox come out
          wrong when using ExtraGlyphs.
        - \[makeInstances\] Fixed rounding bug that could (rarely) cause
          makeInstances to think that a composite glyph is being scaled (which
          is not supported by this script) when it is not.
        - \[makeotf\] Fixed bug in generating TTF fonts from TTF input.
          Previous version simply did not work.
        - \[spot\] Added support for "Small" fonts, an Adobe internal
          Postscript variant used for CJK fonts.
        - \[spot\] Added support for large kern tables, such as in the Vista
          font Cambria, where the size of the kern subtable exceeds the value
          that can be held in the subtable "length" field. In this case, the
          "length" filed must be ignored.
        - \[spot\] Fixed proof option to show GPOS records in GID order by
          default, and in lookup order only with the '-f' option. It had
          always been proofing the GPOS rules in lookup order since 2003.
        - \[spot\] Fixed double memory deallocation when dumping TTC files;
          this could cause a crash.
        - \[spot\] When decompiling GSUB table to feature file format (-t
          GSUB=7) and reporting skipped lookups identify lookups which are
          referenced by a chaining contextual rule.
        - \[sfntedit\] Changed final "done" message to be sent to stdout
          instead of stderr. Reported by Adam Twardoch.
        - \[stemHist\] Fixed typo in help text, reported by Lee Digidea:
          '-all' option was not working.
        - \[tx\] Added new option '-std' to force StdEncoding in output CFF
          fonts.
        
        2.5.21898 (released 2009-05-01)
        -------------------------------
        
        - \[autohint/checkOutlines\] Fixed rare case when an _rrcurveto_ is
          preceded by such a long list of _rlineto_ that the stack limit is
          passed.
        - \[autohint/checkOutlines\] Fixed to restore font.pfa output file to
          StandardEncoding Encoding vector. Since requirements of CFF
          StandardEncoding differs from Type 1 StandardEncoding, a
          StandardEncodingEncoding vector in a Type 1 font was sometimes
          getting converted to a custom Encoding vector when being
          round-tripped through the CFF format which autohint does internally.
        - \[checkOutlines\] Fixed random crash on Windows due to buffer
          overrun.
        - \[checkOutlines\] Changed default logging mode to not report glyph
          names when there is no error report for the glyph.
        - \[CompareFamily\] Added "ring" to the list of accent names used to
          find (accented glyph, base glyph) pairs for Single Face Test 23.
          Reported by David Agg.
        - Renamed showfont to fontplot2 to avoid conflict with the Mac OSX
          showfont tool.
        - Fixed problem with showing vertical origin and advance: was not
          using VORG and vmtx table correctly.
        - \[FontLab scripts\] Added logic to Instance Generator to support
          eliminating "working" glyphs from instances, to substitute
          alternate glyph designs for specific instances, and to update more
          Font Dict fields in the instance fonts. Added help.
        - Added command line equivalent, "makeInstances' which does the same
          thing, but which uses the IS tool for making the snapshot. See the
          'IS' entry.
        - \[IS\] Added new tool for "intelligent scaling". This uses the
          hinting in an MM font to keep glyph paths aligned when snapshotting
          from MM fonts. The improvement is most visible in glyphs with
          several elements that need to maintain alignment, such as percent
          and perthousand. It is also useful for the same reason when scaling
          fonts from a large em-square size to a smaller size. To be
          effective, the source MM font must be hinted and must have global
          alignment zones defined. The new font must be re-hinted. For
          instances from MM fonts especially, it is a good idea to redo the
          alignment zones, as the blending of the MM base designs usually does
          not produce the best alignment zones or stem widths for the instance
          fonts. makeInstances and "Instance Generator" scripts allow you to
          preserve these modifications when redoing the MM instance snapshot.
        - \[makeotf\] Fixed generation of version 1.2 GDEF table to match the
          final OpenType spec version 1.6. This version is generated only when
          the new lookup flag 'UseMarkFilteringSet" is used.
        - \[makeotf\] Fixed generation of names for stylistic alternates
          features. There was a bug such that in some circumstances, the
          feature table entry for the stylistic alternate feature would point
          to the wrong lookup table.
        - \[makeotf\] Fixed generation of the reverse substitution lookup
          type. This was unintentionally disabled just before the previous
          release.
        - \[makeotf\] Fixed bugs in memory management of glyph objects. If the
          font built, it was correct, but this bug could cause the font to
          fail to build.
        - \[spot\] Fixed to dump GDEF table version 1.2 according to the final
          OpenType spec version 1.6.
        - \[spot\] Fixed feature-format dump of the lookupflags
          MarkAttachmentType and UseMarkFilteringSet to give a class name as
          an argument, rather than a class index.
        - \[spot\] Extended the GDEF table dump to provide a more readable
          form.
        - \[spot\] Added dump formats for htmx and vtmx to show the advance
          and side bearing metrics for all glyphs.
        
        2.5.21340 (released 2009-01-22)
        -------------------------------
        
        - \[AGLFN\] (Adobe Glyph List for New Fonts) Created new version 1.7.
        - \[AGLFN\] Reverted to the AGLFN v1.4 name and Unicode assignments
          for Delta, Omega, and mu. The v1.6 versions were better from a
          designer's point of view, but we cannot use name-to-Unicode value
          mappings that conflict with the historic usage in the Adobe Glyph
          List 2.0. See
          <http://www.adobe.com/devnet/opentype/archives/glyph.html>.
        - \[AGLFN\] Dropped all the 'afii' names from the list: 'uni'
          names are actually more descriptive, and map to the right Unicode
          values under Mac OSX.
        - \[AGLFN\] Dropped all the 'commaccent' names from the list:
          'uni' names map to the right Unicode values under Mac OSX before
          10.4.x.
        - \[autohint\] Converted AC.py script to call a command-line program
          rather than a Python extension module, same way makeotf works, to
          avoid continuing Python version problems.
        - \[autohint\] Fixed to actually emit vstem3 and hstem3 hint operators
          (counter control hints, which work to keep the space between three
          stems open and equal, as in an 'm') - this has been broken since
          the first AFDKO. It will now also look in the same directory as the
          source font for a file named "fontinfo", and will attempt to add
          stem3 hints to the glyph which are listed by name in the name list
          for the keys "HCounterChars" or "VCounterChars".
        - \[autohint\] Fixed old bug where it would only pay attention to the
          bottom four of the top zone specified in the FontDict BlueValues
          list. This results in more edge hints in tall glyphs.
        - \[autohint\] Fixed special case when adding flex operator which
          could result in an endless loop
        - \[autohint\] Added 'logOnly' option, to allow collecting report
          without changing the font.
        - \[autohint\] Added option to specify which glyphs to exclude from
          autohinting.
        - \[autohint\] Suppressed generation and use of `<font-name>.plist`
          file, unless it is specifically requested.
        - \[autohint\] Fixed bug where an extremely complex glyph would
          overflow a buffer of the list of hints.
        - \[checkOutlines\] Improved overlap detection and path orientation:
          it will now work with outlines formed by overlapping many stroke
          elements, as is sometimes done in developing CJK fonts.
        - \[checkOutlines\] added new test for nearly vertical or horizontal
          lines. Fixed bug in this new code, reported by Erik van Blokland.
        - \[CompareFamily\] For the warning that the Full Family name in the
          CFF table differs from that in the name table, changed it to a
          "Warning" rather than "Error", and explained that there is no
          functional consequence.
        - \[CompareFamily\] Removed check that Mac names ID 16 and 17 do not
          exist, as makeotf now does make them. See notes in MakeOTF User
          Guide about this.
        - \[CompareFamily\] Fixed so it works with TTF fonts again.
        - \[makeotf\] Removed code that added a default Adobe copyright to the
          name table if no copyright is specified, and removed code to add a
          default trademark.
        - \[makeotf\] Added support for the lookupflag UseMarkFilteringSet.
          This is defined in the proposed changes for OpenType spec 1.6, and
          is subject to change in definition.
        - \[makeotf\] Dropped restriction that vmtx/VORG/vhea tables will only
          be written for CID-keyed fonts. The presence in the feature file of
          either a 'vrt2' feature of vmtx table overrides will now cause
          these tables to be written for both CID-keyed and name-keyed fonts.
        - \[makeotf\] Added warning when a feature is referenced in the aalt
          feature definition, but either does not exist or does not contribute
          any rules to the aalt feature. The aalt feature can take only single
          and alternate substitution rules.
        - \[makeotf\] Added support for the following lookup types:
        
          - GSUB type 2 Multiple Substitution
          - GSUB type 8 Reverse Chaining Single Substitution
          - GPOS type 3 Cursive Adjustment
          - GPOS type 4 Mark-to-Base Attachment
          - GPOS type 5 Mark-to-Ligature Attachment
          - GPOS type 6 Mark-to-Mark Attachment
        
        - \[makeotf\] Added support for explicit definition of the GDEF table,
          and automatic creation of the GDEF when any of the lookup flag
          settings for ignoring a glyph class is used, or any mark classes are
          defined.
        - \[makeotf\] Support using TTF fonts as input, to build an
          OpenType/TTF font, with the limitation that glyph order and glyph
          names cannot be changed. This is rather ugly under the hood, but it
          works. The MakeOTF.py Python script uses the tx tool to convert the
          TTF font to CFF data without changing glyph order or names. It then
          builds an OpenType/CFF font. It then uses the sfntedit tool to copy
          the TTF glyph data to the OpenType font, and to delete the CFF
          table.
        - \[makeotf\] Added support for building Unicode Variation Selectors
          for CID-keyed fonts, using the new cmap subtable type 14.
        - \[makeotf\] Fixed bug with inheritance of default rules by scripts
          and languages in feature file feature definitions. Explicitly
          defined languages were only getting default rules defined after the
          last script statement, and when a script is named, languages of the
          script which are not named got no rules at all.
        - \[makeotf\] Fixed bug where you could not run makeotf when the
          current directory is not the same is the source font's home
          directory.
        - \[makeotf\] Set OS/2.lastChar field to U+FFFF when using mappings
          beyond the BMP.
        - \[makeotf\] Create the Mac platform name table font menu names by
          the same rules as used for the Windows menu names. Add new keywords
          to the FontMenuNameDB file syntax. If you use the old keywords, you
          get the old format; if you use the new syntax, you get nameIDs 1, 2
          and 16 and 17 just like for the Windows platform.
        - \[makeotf\] Fixed bug in name table font menu names: if you entered
          a non-English Preferred name ("f=") and not a compatible family
          name ("c="), you would end up with a nameID 16 but no nameID 17.
        - \[makeotf\] Fixed bogus 'deprecated "except" syntax' message
          under Windows.
        - \[makeotf\] Fixed bug where contextual pos statements without
          backtrack or lookahead context were writing as a non-contextual
          rule. Reported by Karsten Luecke.
        - \[makeotf\] Added new option to make stub GSUB table when no GSUB
          rules are present.
        - \[makeotf\] Added warning if the aalt feature definition references
          any feature tags that either do not exist in the font, or do not
          contribute any rules that the aalt feature can use.
        - \[sfntdiff\] Fixed so that only error messages are written to
          stderr; all others now written to stdout.
        - \[sfntdiff\] Fixed bug in dump of 'name' table: when processing
          directories rather than individual files, the name table text was
          never updated after the first file for the second directory.
        - \[spot\] Fixed option '-F' to show the contextual rule sub-lookup
          indices, and to flag those which have already been used by another
          lookup.
        - \[spot\] If a left side class 0 is empty, do not report it.
        - \[spot\] For GSUB/GPOS=7 FEA dump, give each class a unique name in
          the entire font by appending the lookup ID to the class names. It
          was just `[LEFTCLASS]()<class index>_<subtable index>`, but
          these names are repeated in every lookup. It is now
          `LEFTCLASS_c<class index>_s<subtable index>_l<lookup
          index>`.
        - \[spot\] When a positioning value record has more than one value,
          print the full 4 item value record. Previously, it would just print
          non-zero values. This was confusing when dumping Adobe Arabic, as
          you would see two identical values at the end of some pos rules. In
          fact, each of these pos rule does have two adjustment values, one
          for x and one for y advance adjustment, that happen to be the same
          numeric value.
        - \[spot\] Fixed to write backtrack context glyphs in the right order.
        - \[tx\] Added option to NOT clamp design coordinates to within the
          design space when snapshotting MM fonts.
        - \[tx\] Added option to subroutinize the font when writing to CFF.
          This option is derived from the same code used by makeotfexe, but
          takes only about 10% the memory and runs much faster. This should
          allow subroutinizing large CJK fonts that makeotfexe could not
          handle. This is new code, so please test results carefully, i.e. if
          you use it, always check that the flattened glyphs outlines from the
          output font are identical to the flattened glyph outlines from the
          input font.
        - \[ttxn\] Added options to suppress hinting in the font program, and
          version and build numbers.
        
        2.0.27 (released 2007-11-10)
        ----------------------------
        
        - \[compareFamily\] Fixed Single Test 3 (reported by Mark Simonson and
          others); the test should compare the Mac platform name ID 4 (name ID
          1 + space + name ID 2) with the target value, but was instead using
          the value of the name ID 18 (Compatible Full Name).
        - \[compareFamily\] Fixed Family Test 2 to print a report that helps
          determine which {platform, script, language, name ID} is present in
          some fonts but not others.
        - \[IS\] Fixed a bug where applying hint-based scaling can cause an
          off-by-1 error when the the _closepath_ position is supposed to
          coincide with the original _moveto_, leading to an effective final
          1-unit _lineto_, that may overlap the initial path. In the old MM
          design world, we worked around this issue by designing the MMs so
          that there was always a one unit difference between a final _curveto_
          point and the original _moveto_. FontLab doesn't support doing that
          automatically, so when making an instance, **IS** will instead simply
          look for cases where the _moveto_ and _closepath_ positions differ by
          one unit, and move the _moveto_ position to coincide with the
          _closepath_ position.
        - \[makeotf\] Fixed bug where specifying thousands of singleton kern
          pairs could silently overflow offsets, and makeotf would build a bad
          font without any warning. (reported by Adam Twardoch)
        - \[makeotf\] Relative file paths can now be used even if the current
          directory is not the source font directory. Project files can now be
          saved to directories other than the source font directory. Note that
          paths stored in project file are relative to the project file's
          directory. (reported by Andreas Seidel)
        - \[makeotf/spot\] Added support for Unicode Variation Sequences (UVSes).
          See MakeOTF User's Guide and
          [Unicode Technical Standard #37](http://unicode.org/reports/tr37/)
        - \[spot\] Fixed bug where contents of 'size' GPOS feature would be
          printed for all dump levels.
        - \[spot\] Fixed failure to process 'post' table format 4.0. which
          occurs in some Apple TT fonts, such as Osaka.dfont
        - Updated Adobe-Japan-1 CMAP files for building CID fonts.
        
        2.0.26 (released 2007-05-05)
        ----------------------------
        
        - Added `featurefile.plist` for BBedit. Install this in the location
          shown at the top of the file; it enables code coloring for FEA syntax.
          The file is in FDK/Tools/SharedData
        - Added `MSFontValidatorIssues.html` to FDK/Technical Documentation. It
          lists the error messages from the MS FontValidator tool that can be
          ignored for OpenType/CFF fonts.
        - \[FontLab macros\] Added InstanceGenerator. Another script for making
          instances from an MM VFB font. It's simpler than MakeInstances macro.
        - \[FontLab macros\] Removed debug statement in Set Start Points which
          blocked processing more than 50 glyphs. (reported by George Ryan)
        - \[FontLab macros\] Added explanation of CheckOutlines errors to help
          dialog.
        - \[checkOutlines\] Added option '-he' to print explanation of error
          messages.
        - \[compareFamily\] Added error if the font's CFF table contains a
          Type 2 `seac` operator. The CFF spec does not support this operator.
          Some very old tools allow this to happen.
        - \[makeotf\] Fixed a bug in decomposing glyphs that are defined as
          composite glyphs in a Type 1 source font. This bug caused the base
          component to be shifted when then left side bearing of the composite
          glyph differs from that of the base glyph. This could be consequential,
          as FontLab has an option to not decompose composite glyphs when
          generating a Type 1 font.
        - \[makeotf\] Fixed a bug in recognizing the "Korea1" order when trying
          to pick a default Mac cmap script ID from a CID-keyed font's ROS
          (Registry-Order-Supplement) field.
        - \[tx\] Fixed a bug in decomposing pretty much all composite glyphs
          from Type 1 and CFF source fonts. It happened only when a Type 1 or
          CFF font was being subset, i.e. converted into a font with fewer
          glyphs. tx now has the option '+Z' to force this to occur.
        
        2.0.25 (released 2007-03-30)
        ----------------------------
        
        - \[autohint\] Added a new option to allow extending the list of glyph
          names for which autohint will try to make counter hints.
        - \[autohint\] Fixed bug where Type 2 operator stack limit could be
          exceeded when optimizing Type 2 charstrings during conversion from
          bez format.
        - \[autohint\] Fixed bug in setting OtherBlues alignment zone values.
        - \[FontLab macros\] The Autohint macro behaves quite differently when
          adding 'flex' hints is turned off; it makes more hint substitutions,
          since these are not allowed within the segment of the outline that
          contributes the 'flex' stem. Turned it on, so that hint results will
          be the same as the command-line tool. This does not affect the outline
          data.
        - \[checkOutlines\] Fixed bug that prevented the reporting of two
          successive points with the same coordinates. The code to convert from
          the source outline data to bez format was suppressing zero-length line
          segments, so the checkOutlines module never experienced the problem.
        - \[compareFamily\] Added new options '-st n1,n2..' and '-ft n1,n2..' to
          allow executing only specific tests.
        - \[compareFamily\] Fixed test "Warn if a style-linked family group does
          not have FamilyBlues". When reporting the error that FamilyBlues differ
          in a style-linked family group (where at least one font does have real
          FamilyBlues), use BlueValues as implied FamilyBlues when the latter
          attribute is missing from a font. Same for FamilyOtherBlues.
        - \[compareFamily\] Warn about zones outside of font's BBox only if the
          entire zone is outside of the BBox, not just one edge, and warn only
          for BlueValue zones, not FamilyBlueValue zones.
        - \[compareFamily\] Fixed fsType check. Complain if fsType is not 8 only
          for Adobe fonts, determined by checking if the name table trademark
          string is empty or contains "Adobe".
        - \[compareFamily\] Fixed Single Face Test 3 to compare the CFF Full Name
          with the name table Preferred Full Name (ID 18) rather than the Full
          Name (ID 4).
        - \[compareFamily\] Fixed bug where it failed with CID fonts, because it
          referenced the "Private" dict attribute of the font's topDict, which
          does not exist in CID fonts.
        - \[compareFamily\] Fixed 'size' test to support the format that indicates
          only intended design size, where no range is supplied.
        - \[compareFamily\] Fixed ligature width check to also check that left
          and right side bearings match those of the left and right components,
          and to use the 'liga' feature to identify ligatures and their components,
          instead of heuristics based on glyph names.
        - \[makeotf\] Disallowed negative values in the feature file for the OS/2
          table winAscent and winDescent fields.
        - \[makeotf\] Fixed a bug where a lookup excluded with the `exclude_dflt`
          keyword was nevertheless included if the script/language was specified
          with a languagesystem statement.
        - \[makeotf\] Fixed issue on Windows where a user would see a debug
          assert dialog when the OS/2 vendorID was not specified in the feature
          file, and the Copyright string contained an 8-bit ASCII character, like
          the 'copyright' character.
        - \[makeotf\] Fixed issue on Windows where name ID 17 would be garbage if
          no FontMenuNameDB was supplied, and the PostScript name did not contain
          a hyphen.
        - \[makeotf\] Added warning for Mac OSX pre 10.5 compatibility: total size
          of glyphs names plus 2 bytes padding per glyph must be less than 32K, or
          OSX will crash.
        - \[makeotf\] Fixed crash that occurred if the feature file did not have
          a languagesystem statement.
        - \[makeotf\] Fixed bug in subroutinizer which allowed a subroutine stack
          depth of up to 10, but the Type 1 and Type 2 specs allow only 9. This
          caused most rasterizers to declare the font invalid.
        - \[makeotf\] Removed '-cv' option; CJK vertical CMaps have not been
          supported since FDK 1.6.
        - \[spot\] Added support for low-level and feature file style
          text dumps of GPOS Attachment formats 3, 4, 5 and 6.
        - \[spot\] Added dump of lookup flag value to the feature-file style
          report.
        - \[spot\] Added MarkAndAttachmentClassDef record to GDEF table report.
        - \[spot\] Added support for GSUB lookup type 2 (Multiple) when within
          contextual substitutions.
        - \[spot\] Fixed bug in GSUB lookup 5, causing crash in dumping trado.ttf.
        - \[spot\] Fixed bug in level 7 (feature-file syntax) dump of GPOS table;
          was omitting the value record for extension lookup types.
        - \[spot\] Fixed crash on Windows when proofing contextual substitution
          statements.
        - \[spot\] Made Windows version behave like Mac when proofing: PostScript
          file data is always sent to standard output, and must be re-directed to
          a file.
        - \[spot\] Improved documentation of proofing output and '-P' option.
        - \[spot\] Fixed DSIG table reporting of TTC fonts with the version 2 TTC
          header, even if the header reports it is version 1, like meiryo.ttc.
        - \[spot\] Enabled proofing TTC fonts that don't have glyph names in the
          post table.
        - \[spot\] Fixed origin offset of bounding box for TTF fonts.
        - \[spot\] Fixed crash in proofing TTF fonts when the last glyph is
          non-marking, like trado.ttf in LongHorn.
        
        2.0.24 (released 2006-11-06) — Public release of FDK 2.0
        ----------------------------
        
        - \[autohint/checkOutlines/ProofPDF\] Fixed glyph name handling to avoid
          stack dump when glyph is not in font. Added support for CID values that
          are not zero-padded to 5 hex digits.
        - \[autohint\] Fixed bug where edge hints would be generated rather than
          regular hints across the baseline, when there were fewer than 8 pairs of
          BlueValues.
        - \[checkOutlines\] Fixed bug where it would not report an overlap if
          there were an even number of overlapping contours.
        - \[compareFamily\] Fixed Italic angle Single Test 12 to look at the middle
          third of the test glyph stems, rather than the top and bottom of the
          glyph bounding box, when guessing the font's italic angle.
        - \[compareFamily\] Fixed Single Test 15 to allow a difference of 1 unit in
          the font BBox, to allow for rounding differences.
        - \[compareFamily\] Fixed Single Test 26 to identify uXXXX names as valid
          Unicode names; had bug in the regular expression that required 5 digits.
        - \[compareFamily\] Fixed Single Test 22 to treat glyphs in the combining
          mark Unicode range u3000-u036F range as accent glyphs; require that they
          have the same width as the base glyph.
        - \[compareFamily\] Changed report from Error to Warning for check that
          only the first four Panose values are non-zero.
        - \[compareFamily\] Fixed bug that caused a stack dump in Single Test 16
          and 22.
        - \[compareFamily\] Added tests for Mac OSX pre 10.4 compatibility: no
          charstring is < 32K, total size of glyphs names plus padding is less
          than 32K.
        - \[compareFamily\] Added test that known shipping font does not have OS/2
          table version 4, and that new fonts do.
        - \[compareFamily\] Fixed Single Test 11: allow BASE offset to differ from
          calculated offset by up to 10 design units before it complains.
        - \[compareFamily/makeotf\] Fixed failure when tools path contains a space.
        - \[kernCheck\] New tool; looks for kern GPOS rules that conflict, and also
          looks for glyph pairs that overlap.
        - \[kernCheck\] Added option to allow running only the check of GPOS
          subtables for kerning rules that mask each other.
        - \[makeotf\] Fixed '-adds' option.
        - \[makeotf\] Added new option '-fi' to specify path to fontinfo file.
        - \[makeotf\] Added new option '-rev' to increment the fontRevision field.
        - \[makeotf\] If the (cid)fontinfo file contains the keyword/value for
          FSType, will check that the value is the same as the OS/2 fsType field
          in the final OTF font. This has to do with historic Adobe CJK font
          development practices.
        - \[makeotf\] Added support for setting some of the Plane 1+ bits in the
          OS/2 ulUnicodeRange fields.
        - \[mergeFonts\] Will now apply to the output font the values for the
          fields Weight and XUID, from the cidfontinfo file.
        - \[spot\] Added support for showing some of the Plane 1+ bits in the OS/2
          ulUnicodeRange fields.
        - \[stemHist\] When requiring that reports not already exist, don't delete
          older stem reports when asking for new alignment zone reports, and
          vice-versa.
        - \[setsnap.pl\] New tool to pick standard stem hint values. This Perl
          script takes in the report from stemHist, and recommends a set of values
          to use for the Type 1 font standard stem arrays. This is not as good as
          choosing the most relevant values yourself, but better than not providing
          any values.
        - In _Overview.html_, added warning about 'languagesystem Dflt dflt' and FDK
          1.6 feature files.
        - In _MakeOTFUserGuide.pdf_, expanded discussion of fontinfo file, updated
          documentation of OS/2 v4 table bits with Adobe's practices for the next
          library release.
        - In _OT Feature File Syntax.html_, fixed incorrect sign for winAscent
          keyword, extended discussion of DFLT script tag and useExtension keyword,
          and fixed minor typos.
        - Added two new tech notes on using rotateFont and mergeFonts.
        
        2.0.22 (released 2006-09-12)
        ----------------------------
        
        - \[compareFamily\] Single Test 3 now also checks that Mac name ID 4 starts
          with Preferred Family name, and is the same as the CFF table Full Name.
        - \[compareFamily\] Added test for existence and validation of BASE table
          in Single Test 11.
        - \[compareFamily\] Fixed bug where failed when reporting font BBox error.
        - \[compareFamily\] Added test that some specific glyph names were not
          changed from previous version of font, in Single Test 26.
        - \[compareFamily\] Added "Single Face Test 27: Check
          strikeout/subscript/superscript positions". Checks values against default
          calculations based on the em-box size.
        - \[compareFamily\] Added "Single Face Test 28: Check font OS/2 codepages
          for a common set of code page bits". Checks OS/2 ulCodePageRange and
          ulUnicodeRange blocks against the default makeotf heuristics.
        - \[compareFamily\] Added in Single Test 12 a rough calculation of the
          italic angle. Warns if this is more than 3 degrees different than the
          post table Italic angle value.
        - \[compareFamily\] Added in Family Test 15 a check that all fonts in a
          preferred family have the same hhea table underline size and position
          values.
        - \[compareFamily\] Added "Family Test 16: Check that for all faces in a
          preferred family group, the width of any glyph is not more than 3 times
          the width of the same glyph in any other face".
        - \[compareFamily\] Fixed Family Test 3 to be more efficient.
        - \[makeotf/makeotfexe\] Added a new option '-maxs `<integer>`' to limit
          the number of subroutines generated by subroutinization. Used only when
          building test fonts to explore possible errors in processing the
          subroutines.
        - \[makeotf/makeotfexe\] Allow working names to be longer than 31
          characters; warn but don't quit, if final names are longer than 31
          characters.
        
        2.0.21 (released 2006-08-31)
        ----------------------------
        
        - \[makeotf\] Fixed bug where 'size' feature was built incorrectly when it
          was the only GPOS feature in the font.
        - \[spot\] Improved error messages for 'size' feature problems.
        - \[compareFamily\] Added dependency on environment variables:
          **CF_DEFAULT_URL** should be set to the foundry's URL; it's compared
          with name ID 11.
          **CF_DEFAULT_FOUNDRY_CODE** should be set to the foundry's 4-letter
          vendor code; it's compared with OS/2 table achVendID field.
        - \[compareFamily\] Check that CFF PostScript name is the same as Mac and
          Windows name table name ID 6.
        - \[compareFamily\] Check that named IDs 9 and 11 (designer name and
          foundry URL) exist.
        - \[compareFamily\] Extended Single Test 4 to verify that version string
          is in correct format '(Version|OTF) n.nnn'.
        - \[compareFamily\] Improved Panose test to check that values are not all
          0, and that the CFF font dict 'isFixedPitch' field matches the Panose
          monospace value.
        - \[compareFamily\] Added check to confirm the presence of Unicode cmap
          sub table.
        - \[compareFamily\] Added check to confirm that latn/dflt and DFLT/dflt
          script/languages are present, if there are any GPOS or GSUB rules. Also
          checks that script and language tags are in registered lists, and that
          all faces have the same set of language and script tags, and feature
          list under each language and script pair.
        - \[compareFamily\] Added check to confirm that all faces in the family
          have the same OS/2 table fsType embedding permission values.
        - \[compareFamily\] Added check to confirm that if font has Bold style
          bit, the CFF forceBold flag is on. Also vice-versa, if the font weight
          is less than 700.
        - \[compareFamily\] Added check to confirm that the font does not have a
          UniqueID or XUID, if it's not CID-keyed.
        - \[compareFamily\] Added glyph name checks: OS/2 default char is .notdef,
          and that there are NULL and CR glyphs in TrueType fonts, and that names
          conform to the current Adobe Glyph Dictionary. Note that latest practice
          is to use 'uni' names for final names for all the 'afii' glyphs.
        - \[compareFamily\] Fixed family BlueValues tests to compare within
          compatible family name groups.
        - \[compareFamily\] Changed Family Test 2 to check that all name IDs
          except 16, 17, 18, are all present with the same language/script values
          within all faces of a preferred family.
        - \[compareFamily\] Changed Single Test 3, which didn't do at all what it
          described.
        - \[FontLab macros\] Fixed bug introduced when changing modules shared
          with command-line scripts in build 19.
        
        2.0.20 (released 2006-08-14)
        ----------------------------
        
        - \[ProofPDF\] Fixed bug in waterfallplot mode, where Acrobat would
          report the output PDF file as being damaged.
        - \[makeotf\] Fixed bug that prevented building CID fonts in release
          mode, introduced in build 19.
        
        2.0.19 (released 2006-08-04)
        ----------------------------
        
        - \[compareFamily\] Added Family Test 13 to report error if two fonts in
          the same preferred family have the same OS/2 weight, width and Italic
          settings, and the OS/2 version is greater than 3. Also reports an error
          if the fsSelection field bit 8 "WEIGHT_WIDTH_SLOPE_ONLY" is set
          differently across faces of the same preferred family name group.
        - \[compareFamily\] Fixed Family Test 12 to not fail when the font has a
          script/language with no DefaultLangSys entry.
        - \[makeotf\] If a font file with the requested output file name already
          exists, will delete it before running makeotfexe, so can tell if it
          failed.
        - \[makeotf\] Will now set the new 'fsSlection' bits if the following
          key/value pairs are in the 'fontinfo' file:
        
                PreferOS/2TypoMetrics 1
                IsOS/2WidthWeigthSlopeOnly 1
                IsOS/2OBLIQUE 1
        
        - \[digiplot\] Added new option to specify the font baseline, so the
          baseline can be set correctly when proofing a font file without a BASE
          table.
        - \[digiplot\] Allowed using a CID layout file to supply meta info when
          proofing name-keyed fonts.
        - \[ProofPDF\] Added two functions: **waterfallplot** and **fontsetplot**.
          waterfallplot does not yet work with TrueType or CID-keyed fonts.
        
        2.0.17 (released 2006-05-15)
        ----------------------------
        
        - Fixed multiple tools to allow installing the FDK on Windows on a path
          containing spaces.
        - \[autohint\] Added option to suppress hint substitution.
        - \[autohint\] Fixed help and message to refer to 'autohint' tool name,
          rather than to the AC script file name.
        - \[autohint\] Fixed bug in processing hint masks: bytes with no bits set
          were being omitted.
        - \[autohint\] Added option to allow hinting fonts without StdHW or StdVW
          entries in the font Private font-dictionary.
        - \[checkOutlines\] Fixed writing out the changes when fixing outlines.
        - \[checkOutlines\] Fixed bug that mangled outlines when three alternating
          perpendicular lines or vh/hv/vv/hh curveto's followed each other.
        - \[checkOutlines\] Will now write report to a log file as well as to
          screen. Added option to set log file path, and added numeric suffix to
          name so as to avoid overwriting existing log files.
        - \[compareFamily\] Fixed issue that happened when looking through the
          directory for font files, when encountering a file for which the user
          did not have read permission.
        - \[compareFamily\] Added Single Test 24: check that 'size' feature
          Design Size is within the design range specified for the font.
        - \[ProofPDF\] Added **showfont** command to show how to customize a
          command file to produce a different page layout.
        - \[ProofPDF\] Fixed so fonts with em-square other then 1000 will work.
        - \[fontplot/charplot/digiplot/hintplot/showfont\] Added support for
          Type 1 font files as well as OTF and TTF files.
        - \[makeotf\] Fixed MakeOTF to survive being given a font path with spaces.
        - \[makeotf\] Fixed '-S' and '-r' options.
        - \[makeotf\] Added new option '-osv `<number>`' to allow setting the OS/2
          table version number.
        - \[makeotf\] Added new option '-osbOn `<number>`' to set arbitrary
          bitfields in OS/2 table 'fsSelection' to on. May be repeated more than
          once to set more than one bit.
        - \[makeotf\] Added new option '-osbOff `<number>`' to set arbitrary
          bitfields in OS/2 table 'fsSelection' to off. May be repeated more than
          once to unset more than one bit.
        - \[makeotf\] If neither '-b' nor '-i' options are used, check for a file
          'fontinfo' in the same directory as the source font file, and set the
          style bits if these key/values are found:
        
                IsBoldStyle true
                IsItalicStyle true
        
        - \[FontLab macros\] Built the autohint and checkOutline libraries (PyAC
          and focusdll) linked with Python2.3 so they work with FontLab 5.
        - \[mergeFonts\] Added option to copy only font metrics from first source
          font.
        - \[mergeFonts\] Allow empty lines and "#" comment lines in glyph alias
          and in cidfontinfo files.
        - \[rotateFont\] Fixed bug where it did not allow negative numbers.
        - \[rotateFont\] Allow empty lines and "#" comment lines in rotation info
          file
        - \[sfntedit\] Fixed so that it will not leave the temp file behind on a
          fatal error, nor quit because one already exists.
        - \[spot\] Fixed order of backtrack glyphs in dump of chaining contextual
          `sub` and `pos` statements. Now assumes that these are built in the
          correct order.
        - Added two new tools, **type1** and **detype1**, that compile/decompile
          a Type 1 font from/to a plain text representation.
        
        2.0.5 (released 2006-02-14)
        ---------------------------
        
        - \[compareFamily\] Added warning if sum of OS/2 table sTypoLineGap,
          sTypoAscender, and sTypoDescender is not equal to the sum of usWinAscent
          and usWinDescent.
        - \[compareFamily\] Updated test for allowable weights in style-linked
          faces to reflect the current behavior of Windows XP.
        - \[compareFamily\] Added check for OpenType/CFF: Windows name table ID 4
          (Full Name) is the same as the PostScript name.
        - \[compareFamily\] Added report on sets of features in different
          languagesystems, and an error message if they are not the same in all
          faces of the font.
        - \[compareFamily\] Fixed incorrect message about real error when menu
          names are not correctly built.
        - \[compareFamily\] Fixed test for improbable FontBBOX to use em-square
          rather than assume 1000 em.
        - \[compareFamily\] Added warning if widths of ligatures are not larger
          than the width of the first glyph.
        - \[compareFamily\] Added warning if accented glyphs have a width different
          than their base glyph.
        - \[compareFamily\] Added error message if two faces in the same family
          have the same OS/2 width and weight class and italic style setting, and
          are not optical size variants. Optical size check is crude: the Adobe
          standard optical size names (Caption, Capt, Disp, Ds, Subh, Six) are
          removed from the PS font names and then compared; if the PS names are
          the same, then they are assumed to be optical size variants.
        - \[compareFamily\] Added check that no hint is outside the FontBBox, for
          CJK fonts only.
        - \[spot/otfproof\] Added "Korean" to list of tags for OS/2 codepage range.
        - \[spot/otfproof\] Fixed dump of 'size' feature to support correct and old
          versions
        - \[spot/otfproof\] Added dump/proof of contextual chaining positioning
          format 3.
        - \[spot/otfproof\] Added warnings that only low-level dump of other
          contextual lookups is supported.
        - \[makeotf\] Program is now a stand-alone C executable.
        - \[makeotf\] Removed option to write contextual positioning rules in the
          _old_ incorrect format.
        - \[makeotf\] MakeOTF no longer assigns Unicode Private Use Area values
          to glyphs for which it cannot identify. To use PUAs, explicitly assign
          them in the GlyphOrderAndAlias file.
        - \[makeotf\] Fixed bug in name table name ID "Version": if version decimal
          value is x.000, then the value in the Version name ID string was x.001.
        - \[makeotf\] Fixed bug in handling of DFLT language script: it's now
          possible to use this tag.
        - \[makeotf\] Fixed feature file parsing bug where 'dflt' lookups in one
          feature were applied to the following feature if the following feature
          started with a language statement other than 'dflt'.
        - \[makeotf\] Fixed serious bug where wrong width is calculated for glyphs
          where the CFF font Type 2 charstring for the glyph starts with a width
          value. This is then followed by the value pairs for the coordinates for
          the vertical hint, and then these are followed by a hint mask or control
          mask operator. The bug was that when MakeOTF reads in the charstring in
          order to derive the hmtx width, it discards the data before the control
          mask operator, leading the parser to use the CFF default width for the
          glyph.
        - \[makeotf\] vhea.caretSlopeRise and vhea.caretSlopeRun is now set to 0
          and 1 respectively, rather than the opposite.
        - \[makeotf\] The OS/2 table 'fsType' field is now set to the feature file
          override. If not supplied, then the value of the environment variable
          FDK_FSTYPE. If not set then 4 (Preview & Print embedding).
        - \[makeotf\] Added support for contextual chaining positioning of base
          glyphs; mark and anchors not yet supported.
        - \[makeotf\] Fixed bug in 'size' feature: the feature param offset is now
          set to the offset from the start of the feature table, not from from the
          start of the FeatureList table.
        - \[makeotf\] Allowed 'size' feature point sizes to be specified as
          decimal points, as well as in integer decipoints.
        - \[makeotf\] OS/2 table version is now set to 3.
        - \[makeotf\] Added OS/2 overrides for winAscent and winDescent.
        - \[makeotf\] Added hhea overrides for Ascender/Descender/LineGap.
        - \[makeotf\] Set OS/2 Unicode coverage bits only if the font has a
          reasonable number of glyphs in the Unicode block; it was setting the
          bits if the font had even one glyph in the block.
        - \[makeotf\] The "Macintosh" codepage bit in the OS/2 codePageRange fields
          is now set by default.
        - \[FEA spec\] Fixed incorrect range example in section _2.g.ii. Named
          glyph classes_
        - \[FEA spec\] Changed rule to allow lookup definitions outside of feature
          definitions in FDK 2.0.
        - \[FEA spec\] Fixed incorrect uses of 'DFLT' rather than 'dflt' for a
          language tag.
        
        1.6.8139 (released 2005-08-30)
        ------------------------------
        
        - \[OTFProof\] Fixed error in dumping GSUB table: GSUB lookup 5,
          context lookup assumed that there were both a lookahead and a backtrack
          sequence.
        - Updated SING META table tags to latest set.
        
        1.6.7974 (released 2004-08-30)
        ------------------------------
        
        - \[makeotf\] Fixed rule in building CJK font. When looking for Adobe
          CMap files, will no longer use a hardcoded max supplement value when
          building paths to try.
        
        1.6.7393 (released 2004-01-14)
        ------------------------------
        
        - \[compareFamily\] Fix stack dump when family has no BlueValues
          (reported by House Industries).
        - \[compareFamily\] Fix stack dump when CFF-CID font has glyph with no
          `subr` calls.
        - \[OTFProof\] Corrected error in last release, where spaces between
          ligature match string names were omitted.
        - \[FontLab macros\] Added scripts for testing if the joins in a
          connecting script font design are good.
        - \[OTFProof\] Fixed crash on proofing or dumping feature file syntax for
          GSUB lookup 5, context lookup. Also fixed rule-generating logic:
          results were previously wrong for proof and for feature-file syntax
          formats. Text dump has always been correct.
        - \[OTFProof\] Fixed crash when dumping cmap subtables that reference
          virtual GIDs not in the font.
        - \[OTFProof\] Fixed crash on dumping GSUB lookup type 6 chaining context
          subtable format 2. This has never worked before.
        - \[OTFProof\] Added demo for SING glyphlet tables, SING and META.
        - \[FontLab macros\] Added scripts for reading and writing an external
          composites definition text file.
        - \[FontLab macros\] Added scripts for working with MM fonts.
        
        1.6.6864 (released 2003-10-08)
        ------------------------------
        
        - \[OTFProof\] Fixed crash after dumping contents of ttc fonts (bug
          introduced in version 6792).
        - \[OTFProof\] Fixed cmap subtable 4 and 2 dumps. Cmap subtable 2 could
          show encoding values for single byte codes which were really the
          first byte of two byte character codes. In Format 4, idDelta values
          were not being added when the glyphindex was derived from the glyph
          index array. These show issues show up in some TTF CJKV fonts.
        
        1.6.6792 (released 2003-09-24)
        ------------------------------
        
        - \[OTFProof\] Fixed crash when proofing fonts with _many_ glyphs.
        - \[OTFProof\] Restored "skipping lookup because already seen in
          script/language/feature" messages to proof file, which was lost in
          version 6604.
        - \[OTFProof\] Added ability to proof resource fork sfnt fonts from Mac
          OSX command line. It's still necessary to use the SplitForks tool to
          make a data-fork only resource file, but spot/otfproof can now navigate
          in the resulting AppleDouble formatted resource file.
        - \[OTFProof\] Added support for a text dump of the GDEF table.
        - \[OTFProof\] Changed title in 'size' feature dump from _Common
          Characters_ to _name table name ID for common Subfamily name for size
          group_.
        - \[AGL\] Fixed some minor errors in the Adobe Glyph List For New Fonts.
        
        1.6.6629
        --------
        
        - \[OTFProof\] Fixed bug in dumping KERN table from Mac sfnt-wrapped
          resource fork Type 1 MM font.
        - \[OTFProof\] Changed the AFM-format dump of kern pairs to list all
          kern pairs for each language/script combination in separate blocks, and
          to eliminate all class kern pairs that are masked by a singleton kern
          pair. The temp buffer file path is now taken from the system C library
          function tmpnam(), and is not necessarily in the current directory.
        
        1.6.6568
        --------
        
        - \[OTFProof\] Fixed command-line tool to write proof files in same
          location as font, and with font-name prefix, when not auto-spooled for
          printing.
        - \[OTFProof\] Fixed bug in UI version where proofing GSUB features and
          then GPOS features would cause the GPOS feature proof files to be empty.
        - \[makeotf\] Fixed heuristics for picking OS/2 weight/width so that a
          font name containing _ultracondensed_ would trigger only setting the
          width, and not the weight as well.
        - Updated Mac OS project files to CodeWarrior 8.
        
        1.6.6564
        --------
        
        - \[OTFProof\] When dumping data from TTF fonts, now add `@<gid>` to all
          glyph names. This is because the rules for deriving names can lead to
          two glyphs being given the same name.
        - \[OTFProof\] Fixed bug in proofing GPOS class kern pairs: was generating
          bogus kern pairs and duplicate kern pairs when the coverage format was
          type 2. Affects proof file only, not AFM or feature-format dump.
        - Fixed memory overwrite bug encountered by Goichi and cleaned up various
          memory leaks in the process.
        - \[compareFamily\] Added report on whether a face contains known std
          charset. Stub implementation - still need list of std charsets.
        - \[AFM2Feat\] Developed tool to convert an AFM file to a file with
          kern feature `pos` rules.
        
        1.6.6148
        --------
        
        - Rebuilt all libraries for v1.6 release 3/10/2003.
        
        1.6.6048
        --------
        
        - Updated FinishInstall.py to reflect Python 2.2 requirements.
        - Picked up last MakeOTF.pdf editing changes.
        - Fixed bug in GOADB.
        - Updated CID font data in example fonts.
        - Updated FDK release notes and installation instructions.
        - Updated to use the GlyphOrderAndAliasDB file developed while
          converting the Adobe Type Library. Maps all the old glyph names to AGL
          compatible names.
        
        1.6.6020
        --------
        
        - \[OTFProof\] Fixed crash in handling of VORG with no entries. (Vantive
          574752)
        - \[MakeOTF\] Updated documentation: added a description of how all three
          columns of the _GlyphOrderAndAliasDB_ file are used; added a new section
          on the key-value pairs of the font project file; updated the description
          of the FontMenuNameDB file entries; added minor clarifications throughout.
        - Updated _digital_signature_guide.htm_ to match current Verisign website.
        - \[Example fonts\] Changed the incorrect language keyword TUR to TRK.
        - \[Example fonts\] Removed the many key/value pairs in the fontinfo files
          that are not used by MakeOTF.
        - \[OTFProof/spot\] Fixed 3-column handling of GOAADB. (Vantive 569681)
        
        1.6.5959
        --------
        
        - \[MakeOTF\] Suppressed the "repeat hint substitution discarded" message
          from the source file parsing library. These are so common that they
          obscure more useful messages.
        - \[MakeOTF\] Set as default the option to build chaining contextual
          substitution rules with the incorrect format used by InDesign 2.0 and
          earlier.
        - \[MakeOTF\] If the option above is set, then MakeOTF will write a name
          ID (1,0,0,5 - "Version") which will contain the text string which
          triggers special case code in future Adobe apps so that it will process
          the chaining contextual substitution rules as they were intended. If
          this option is NOT set, the name ID 5 will be written so as to not
          trigger this special case code. The special case treats specially any
          font where the name table name ID (1,0,0,5) exists and either matches,
        
                "OTF[^;]+;PS[^;]+;Core 1\.0\.[23][0-9].*"
        
          (example: "OTF 1.006;PS 1.004;Core 1.0.35")
          or contains,
        
                "Core[^;]*;makeotf\.lib"
        
          (example: "Core 1.0.38;makeotf.lib1.5.4898")
          or just,
        
                "Core;makeotf.lib"
        
        - \[MakeOTF\] Turn off by default the option to force the .notdef glyph
          in the output OTF font be an crossed rectangle with an advance width
          of 500.
        - \[MakeOTF\] Added rule to force the OS/2 WeightClass to always be at
          least 250. Shows error message if set or calculated WeightClass was less
          than this.
        - \[MakeOTF\] Added test that FSType is set the same in the feature file
          as in source CID font files.
        - \[OTFProof\] Page layout for CJKV font vertical layout: now writes the
          vertical columns right to left.
        - \[OTFProof\] When writing vertical features, now shows the advance width
          sign as negative.
        - \[OTFProof\] When making PostScript proof file, now writes DSC tags with
          correct header and page info.
        - Added _Unicode and Glyph Name_ documentation to the FDK _Technical
          Documentation_ directory, to allow access to this info under the FDK
          license.
        
        1.6.4908
        --------
        
        - \[MakeOTF/FEA syntax\] Added new vmtx table overrides, to allow setting
          vertical metrics for pre-rotated proportional glyphs that are
          specifically designed and are not simply rotated forms of proportional
          glyphs.
        - \[MakeOTF/FEA syntax\] Added new OS/2 overrides to set the Unicode and
          Windows codepage range fields: UnicodeRange CodePageRange.
        - \[MakeOTF/FEA syntax\] Updated language keywords to be consistent with
          OpenType spec, i.e using `dflt` instead of `DFLT`. Expanded section
          explaining use of language and script default keywords. Old keywords
          still work, but cause a warning to be emitted.
        - \[FEA syntax\] Expanded explanation of kern class pairs and subtable
          breaks.
        - \[MakeOTF\] Updated the search rules for CID font CMap files to support
          Adobe-Japan2-0, and to look first for UTF-32 CMAP files.
        
        1.5.4987
        --------
        
        - Release to Adobe website Sept 2002.
        
        1.5.4908
        --------
        
        - \[MakeOTF\] Changed the name table version string to match OT spec 1.4.
        - \[CompareFamily\] Made it _really_ work with Sept 10th 2002 release of
          Just van Rossum's FontTools library.
        
        1.5.4492
        --------
        
        - \[MakeOTF\] (hotlib 1.0.35) Fixed the error in processing GSUB
          contextual chaining substitution format 3. This was originally done
          according to the OpenType spec 1.4, which is in error by the
          established implementation of VOLT and Uniscribe. Added option '-fc' to
          cause the library to use the incorrect implementation, according to OT
          spec v1.4. By default, MakeOTF builds the correct contextual format
          per spec v1.5.
        - \[MakeOTF\] (hotlib 1.0.35) Fixed Unicode cmap bug in assigning the OS/2
          table field usLastCharIndex. This is supposed to be the highest Unicode
          value in the BMP-16 cmap tables. The problem was in the logic by which
          alternates of supplemental plane glyph names were being assigned an EUS
          code, but not added to the BMP-16 Unicode cmap tables, e.g. u1D269.alt.
          When one of these alternates was assigned an EUS value, the
          usLastCharIndex was getting bumped even though the glyph was not being
          added to the BMP-16 cmap tables. Fixed by not incrementing
          usLastCharIndex in this case.
        - \[MakeOTF\] Fixed bug in applying client-supplied Unicode override
          values. These were omitted if the glyph names in the font were different
          than the final glyph names, as can happen when the client uses the
          getFinalGlyphName call back to supply a glyph production name which is
          different than the final glyph name.
        - \[OTFProof\] Fixed crash when proofing liga feature in CID font. Also
          fixed crash when proofing charstring with only one operand, e.g
          h/r/vmoveto.
        - \[CompareFamily\] Updated to use the latest version of Just van Rossum's
          FontTools library, added support for TrueType fonts. Now requires Python
          2.2.
        - \[CompareFamily\] Added family test 11: verify that for base font in
          style-linked group, Mac and Windows menu names are the same, and that
          for other fonts in the style linked group, the Mac and Windows menu
          names  differ.
        
        1.5.4099
        --------
        
        - External release of FDK 1.5 on Adobe website.
        
        1.5.3849
        --------
        
        - \[CompareFamily\] Fixed tabular glyph and isFixedPitch test so that they
          are now useful - used to generate far too many false errors.
        - \[MakeOTF\] Fixed bug in setting Panose values from a feature file
          override. If any value in the Panose value string is 0, all subsequent
          values were also set to 0.

          panose value, report derived panose values as an error.
        - \[CompareFamily\] Fixed bug  in comparing copyright notices in family
          test 7: will now really report error only if differs in other than years.

        - \[CompareFamily\] Fixed to not die on font menu names with non-std ASCII.
        - \[OTFProof\] Fixed vertical metrics proofing.
        - \[MakeOTF\] Added warning when truncating OS/2 TypoAscender to force its
          sum with TypoDescender to be equal to the em-box.
        - \[MakeOTF\] Allow fractional synthetic weight values. These are rounded
          to an integer.
        - \[MakeOTF\] Changed XUID adding algorithm to NOT add the revision number
          to the XUID array.
        - \[MakeOTF\] In release mode, add current year to copyright, suppress (c)
          string, and fix spaces around the phrase 'All Rights Reserved'.
        - \[MakeOTF\] Fixed to permit building a font in release mode with no
          unique ID at all.
        - \[MakeOTF\] Fixed bad cmap entry offset calculation.

        1.5.1023
        --------
        
        - \[MakeOTF\] Changed algorithm for adjusting advance width/lsb/rsb of
          non-slanted synthetic glyphs when adding to italic fonts.
        - \[MakeOTF\] Fixed failure of re-ordering when NOT forcing use of marking
          notdef.
        - \[MakeOTF\] Fixed interaction between 'Sigma' and synthetic 'summation',
          'Pi' and 'product'.
        - \[spot\] Added the option to select which feature to dump in GPOS or
          GSUB=7 dumps.
        - \[OTFProof\] Added support of TT instructions in compound glyphs.
        - \[CompareFamily\] Fixed incorrect unwrapping T2 charstring subroutines.
          All previous reports on whether glyphs were hinted should be doubted.
        - \[MakeOTF\] Tweaked horizontal spacing of upright glyphs in oblique fonts.
        - \[MakeOTF\] Added support for "italicangle", "width" and "weight" keywords
          in FontMenuNameDB.
        - \[SCM/makeotf/typecomp\] Fixed Euro-adding bug.
        - \[OTFProof\] Removed header note "1000 units/em" from proofs.
        - \[OTFProof\] Added support for cmap version 12.
        - \[OTFProof\] Removed zero padding of CID values from text reports.
        - \[OTFProof\] Reduced number of warnings about missing characters.
        - \[OTFProof\] Removed warning when GPOS and GSUB table may be too big,
          as no tools make this error anymore, and it is triggered
          inappropriately when font uses the extension lookup.
        - \[OTFProof\] Fixed different spacing problem reported. (Vantive 420313)
        - \[OTFProof\] Fixed so that vertical proofs write from right to left.
        - \[MakeOTF\] Fixed problem with unspecified CMap files.
        
        1.5.600
        -------
        
        - \[CompareFamily\] Fixed so that it will not error out when one of the
          Blues arrays is not present.
        - \[OTFProof\] Fixed so that glyph names for CID fonts print properly.
        - \[OTFProof\] Fixed problems with compile under SunOS.
        - \[MakeOTF\] Added MakeOTFScript.py as an example file to edited, in
          order to allow scripting of makeOTF on the Mac (or any other platform).
          Minor changes to MakeOTF.py to fix this.
        - \[MakeOTF\] Added an option to allow removing deprecated Type 1 operands
          from output font (e.g. `seac` and `dotsection`).
        - \[MakeOTF\] Added an option to allow adding synthesized glyphs to fonts,
          leveraging a built-in sans and serif multiple master substitution font.
          The source font must contain a 'zero' and a capital 'O'.
          The glyphs that can be synthesized are:
        
                Euro
                Delta

        1.4.583
        -------
        
        - Began tracking files by Perforce changelist label, from the Perforce
          source code management system.
        - Updated compilers to Mac/CodeWarrior 6 Pro, Windows Visual C++ 6.0.
        - Re-organized build directories to have mac/win/sun4 subdirectories.
        - Re-organized shared include files to all be under /Programs/api, with
          non-conflicting names.
        - \[Example fonts\] Updated MinionPro-Capt: now has correct frac and size
          features.
        - \[Example fonts\] Added KozMinPro to samples.
        - \[MakeOTF\] Fixed bug where fontinfo keyword IsStyleBold was ignored for
          CID fonts.
        - \[MakeOTF\] Fixed Mac build project to load debug and release libraries
          by different names.
        - \[MakeOTF\] Added feature file support for the "languagesystem" statement.
          Note that this entailed removing support for script, language, and named
          lookup statements in the size feature, and removing support for script and
          language statements in the aalt feature. See feature file spec for details.
        - \[MakeOTF\] More descriptive wording in offset overflow error messages.
          Feature file error handling improved: multiple error messages are emitted
          before failing if possible, instead of just one; final glyph name as well
          as glyph alias (if applicable) reported if not found in font.
        - \[MakeOTF\] Changed the 14 Corporate Use subarea Unicode values for Zapf
          Dingbats to the proposed UVs in anticipation of their being incorporated
          into the Unicode standard.
        - \[MakeOTF\] Added FontWorks ('FWKS') to vendor ID list.
        - \[MakeOTF\] Increased the maximum number of named lookups allowed to 8192.
        - \[MakeOTF\] Now makes kern and vert features from kern data passed in by
          clients and from V CMap (respectively) only when the HOT_CONVERSION bit is
          set. (Previously, these features were made from the sources mentioned
          above if they weren't already defined in a feature file.)
        - \[MakeOTF\] Fixed an obscure bug in OS/2.ulUnicodeRange computation: if
          the largest UV in the font were not in any Unicode range recognized by
          hotlib then it was counted as being in the next recognized Unicode range
          after the UV. (No known fonts are affected by this.)
        - \[MakeOTF\] Forced the OS/2 codepage range bits for Chinese to either
          Simplified or Traditional, based on the Mac cmap script, if it is defined
          as either Simplified or Traditional, and will fall back to the heuristics
          if the script is undefined. If the mac.script is something other than a
          Chinese script, then the OS/2 codepage range bits for Chinese will not
          be set.
        - \[OTFCompare\] The Python sys.path variable must now contain the path
          to the directory containing the OTFProof library (usually
          _FDK/Tools/Programs/otfproof/exe_). This replaces the hardcoded path
          reference in the OTFCompare.py script. On all platforms, this is done
          by adding the file "otfproof.pth", containing the path, to the Python
          installation.
        - \[OTFCompare\] Fixed a bug that was causing tables smaller than 16 bytes
          to be reported as different
        - \[OTFProof\] Added new proofing mode to CFF_ to print one glyph per page.
        - \[OTFProof\] Added new proofing option to suppress file-specific header
          info to facilitate diff-ing of multiple proofs.
        - \[OTFProof\] Added alphabetical sorting of AFM-style dump.
        - \[OTFProof\] Fixed bug causing GPOS/GSUB features with digits in their
          names to not appear in the proofing list.
        - \[OTFProof\] Added support for glyphsize option in CFF_ dumps.
        - \[OTFProof\] Fixed conflicting include file names; must now specify
          include paths in project file.
        - \[OTFProof\] Reduced some of the recursion in the subroutinization code
          to reduce stack space requirements.
        - \[OTFProof\] Fixed support for included feature files in parent folder
          on the Mac.
        
        1.3.2 (2000-10-24)
        ------------------
        
        - \[OTFProof\] Fixed bug where would report error opening Mac TTF suitcase
          font, because data fork was of size 0.
        - \[OTFProof\] Fixed bug where feature tags containing numbers were filtered
          out of the feature list for proofing.
        - \[OTFProof\] Fixed bug where baseline was shown incorrectly for CJK fonts
          with baselines other than 120.
        - \[OTFProof\] Fixed bug where y-placement changes were not shown correctly
          in vertical writing mode proofs.
        
        1.3.1 (2000-08-15)
        ------------------
        
        - \[MakeOTF\] Fixed problem with heuristics for OS/2 codepage range
          settings, for Chinese Simplified vs Traditional.
        - \[MakeOTF\] Added macro to define MakeOTF version number.
        - \[MakeOTF\] updated makeotflib help/usage messages: shown when args are
          incorrectly formatted.
        
        - \[makeotf\] (makeotf/exe/makeotfutils.py)
        
          - added fontinfo list entry for "Language".
          - added 'parameter' variable entry for same.
          - increased num values to from 34 to 35.
          - changed initialization of 'parameter' so can more easily figure out
            which index matches which fontinfo field.
        
        - \[makeotf\] (makeotf/exe/makeotf.py)
        
          - updated version numbers to 1.3.1.
          - added '-cs' and '-cl' options to help.
          - added processing of Language field, to set script and language IDs
            with '-cs' and '-cl' options.
        
        - \[makeotf\] (makeotf/source/main.c)
        
          - added macro to define MakeOTF version number, used in help message,
            and in client name string for name id 5 "Version".
          - added mac_script and mac_language fields to global static 'convert'
            structure.
          - added processing of '-cs' and '-cl' arguments to parse_args().
          - added mac_script and mac_language arguments to call to cbconvert().
          - updated print_usage to match that of makeotf.py.
          - updated the ReadFontInfo() to process new Language field.
        
        - \[makeotf\] (makeotf/source/cb.c)
        
          - moved initialization (as type unknown) of mac.encoding, mac.script
            and mac.language from cbconvert to cbnew().
          - added setting of mac.script and mac.language to cbconvert(), from
            arguments.
          - added mac_script and mac_language arguments to call to cbconvert().
        
        - \[makeotf\] (source/includes/cb.h)
        
          - added mac_script and mac_language arguments to call to cbconvert().
        
        - \[hotconvlib\] (coretype/source/map.c)
        
          - changed logic for setting OS/2 codepage range to set code page to
            Simplified or Traditional Chinese based on mac.script setting;
            fallback on heuristics only if mac.script is not set.
