zstandard 0.19.0

on Python PyPI

Bug Fixes

• The C backend implementation of ZstdDecompressionObj.decompress() could
  have raised an assertion in cases where the function was called multiple
  times on an instance. In non-debug builds, calls to this method could have
  leaked memory.

Changes

• PyPy 3.6 support dropped; Pypy 3.8 and 3.9 support added.
• Anaconda 3.6 support dropped.
• Official support for Python 3.11. This did not require meaningful code changes
  and previous release(s) likely worked with 3.11 without any changes.
• CFFI's build system now respects distutils's compiler.preprocessor if it
  is set. (#179)
• The internal logic of ZstdDecompressionObj.decompress() was refactored.
  This may have fixed unconfirmed issues where unused_data was set
  prematurely. The new logic will also avoid an extra call to
  ZSTD_decompressStream() in some scenarios, possibly improving performance.
• ZstdDecompressor.decompress() how has a read_across_frames keyword
  argument. It defaults to False. True is not yet implemented and will raise an
  exception if used. The new argument will default to True in a future release
  and is provided now so callers can start passing read_across_frames=False
  to preserve the existing functionality during a future upgrade.
• ZstdDecompressor.decompress() now has an allow_extra_data keyword
  argument to control whether an exception is raised if input contains extra
  data. It defaults to True, preserving existing behavior of ignoring extra
  data. It will likely default to False in a future release. Callers desiring
  the current behavior are encouraged to explicitly pass
  allow_extra_data=True so behavior won't change during a future upgrade.
