DHParser Version 0.8.5 (10.2.2019)
..................................

- optimization: flattens anonymous nodes already while parsing
- optimization: drops empty anonymous nodes already during parsing
- optimization: optionally allows to drop anonymous whitespace and tokens
  while parsing
- major refactorings of node and parser class hierarchy: much simpler now,
  no zombie classes needed any more
- parser_guard() is now integrated into the Parser class: Parsing
  functionality moved to _parse() method, while Parser.__call__() is now the
  new parser guard
- better support for customized error messages + bug fixes
- better cython support (makes it about 2.5 times as fast if cython is used)
- testing.grammar_suite now uses multiprocessing to run tests
- parse.Parser.apply() reworked


DHParser Version 0.8.4 (6.1.2019)
.................................

- customized resuming after parser errors! (still experimental, see
  tests/test_ebnf.TestCustomizedResumeParsing as well as
  tests/test_parse.TestReentryAfterError)
- error messages for parser errors can now be configured to be more
  user friendly (see test/test_ebnf.TestCuratedErrors)
- lookahead parsers can now be unit-tested (experimental)
- customized (faster) deepcopy of syntax trees
- better customization of XML-serialization of syntax-trees
- support for thread-safe globals and configuration data
  via toolkit-module
- development status of package raised to "4 - Beta". It's really quite
  stable now, but backwards incompatible changes may still happen!


DHParser Version 0.8.3 (20.8.2018)
..................................

- new transformation function collapse_if()
- restored compatibility with Python 3.4
- StepByStep Guide typos fixed
- bug fixes


DHParser Version 0.8.2 (10.7.2018)
..................................

- refactoring of module parser.py for more simplicity. RE is now
  a simple (macro-style) function instead of a class of its own.
  Class Token has been merged with PlainText. Possible break of
  backwards compatibility with certain AST-transformation-tables in
  connection with Token and RE-nodes!


DHParser Version 0.8.1 (2.7.2018)
.................................

- compatibility fixes for Python 3.7


DHParser Version 0.8.0 (24.6.2018)
..................................

- refactoring of error reporting: it is now done centrally through the
  (newly introduced) syntaxtree.RootNode object; makes it faster and easier
- "step by step" guide added to the documentation
- XML is now a first class citizen for serialization next to S-expressions:
  xml serialization can now also be read with syntaxtree.parse_xml() plus
  better serialization with syntaxtree.Node.as_xml()
- added example: XML-Parser
- added optional CST-reporting on a case by case basis to the testing
  framework, using the "*"-marker to indicate which test should add CSTs to
  the report
- moved compilation support to a separate module: compile.py
- source mapping added if preprocessor changes source code
  (see module preprocess.py)
- new semantics for syntaxtree.Node.__str__: now includes error messages;
  use Node.content to retrieve the content without any error messages
- LaTeX-example: better AST-transformations.


DHParser Version 0.7.8 (29.11.2017)
...................................

- added parsers for arbitrarily ordered elements (parser.Unordered class)
- various bug fixes
- html based history logs for better readability
- code cleanups


DHParser Version 0.7.7 (2.9.2017)
.................................

- dhparser script now creates and initializes project dir
- parsing is now based on a StringView class which other
  than plain Python strings does not copy strings when
  slicing. (Speeds up parsing for longer documents.)
- AST-transformations now receive the complete context, i.e.
  the list of all parent nodes instead of just the node to
  transform


DHParser Version 0.7.4 (2.7.2017)
.................................

- package now includes 'dhparser' script
- more transformation primitives for AST-transformation
- various bug fixes


DHParser Version 0.7.3 (27.6.2017)
..................................

- bug fixes for setuptools packaging


DHParser Version 0.7.1 (27.6.2017)
..................................

- first PyPI release
- added type annotations for static type checking with mypy
- many changes, some incompatible with prior versions


DHParser Version 0.6.0 (23.4.2017)
..................................

first public release
