Changes in v0.11.0:
  1/ Changed PyPI package name from python-exiv2 to exiv2.
  2/ Simplified some data iterators and function return values.

Changes in v0.10.0:
  1/ API change: replaced Value += operator with append method.
  2/ Improved conversion of LangAltValue to/from Python dict.
  3/ Can construct some other values from a Python list.
  4/ AnyError exception renamed to Exiv2Error (with AnyError wrapper for

Changes in v0.8.3:
  1/ Xmp LangAlt values can be accessed like a Python dict.
  2/ Binary wheels are built with BMFF file support enabled.

Changes in v0.8.2:
  1/ No longer detect possible iterator invalidation (unreliable).
  2/ Restructured macros to give slightly less bloated code.

Changes in v0.8.1:
  1/ Fix some causes of segfaults.
  2/ Slightly change output of Metadatum.__str__().

Changes in v0.8.0:
  1/ Data iterators include checks for end of data and changed data so are less
     likely to segfault.

  3/ API change: removed access to value_ container in data values.

Changes in v0.7.0:
  1/ Add a constructor to Value subclasses that downcasts a Value.
  2/ Deprecated the Value subclass downCast() static method.

Changes in v0.5.1:
  1/ Fix undefined symbol problem with Linux binary wheels.
  2/ XmpProperties.registeredNamespaces() returns a Python dict.

Changes in v0.5.0:
  1/ API change: data iterators no longer have a "curr" method, as all the
     methods of the datum it returned are directly accessible.
  2/ The BasicIo class and its subclasses are no longer available from Python.

Changes in v0.4.0:
  1/ "Easy Access" functions have been added to the interface.
