Version 0.8.0

Due to changes in this version igzip.compress, igzip.decompress,
isal_zlib.compress, isal_zlib.crc32
and isal_zlib.adler32 perform always faster than their gzip and
zlib counterparts. isal_zlib.decompress is still slower for very
small data <128 bytes, but faster in all other cases.

• Speed up igzip.compress and igzip.decompress by improving the
  implementation.
• Make sure compiler arguments are passed to ISA-L compilation step. Previously
  ISA-L was compiled without optimisation steps, causing the statically linked
  library to be significantly slower.
• A unused constant from the isal_zlib library was removed:
  ISAL_DEFAULT_HIST_BITS.
• Refactor isal_zlib.pyx to work almost the same as zlibmodule.c. This has made
  the code look cleaner and has reduced some overhead.

Version 0.7.0

This release fixes several bugs in isal_zlib. It now is a proper drop-in
replacement for zlib. This is a major milestone towards the 1.0.0
release.

• Remove workarounds in the igzip module for the unconsumed_tail
  and unused_data bugs. igzip._IGzipReader now functions the same
  as gzip._GzipReader with only a few calls replaced with isal_zlib
  calls for speed.
• Correctly implement unused_data and unconsumed_tail on
  isal_zlib.Decompress objects.
  It works the same as in CPython's zlib now.
• Correctly implement flush implementation on isal_zlib.Compress and
  isal_zlib.Decompress objects.
  It works the same as in CPython's zlib now.

Version 0.6.1

• Fix a crash that occurs when opening a file that did not end in .gz while
  outputting to stdout using python -m isal.igzip.

Version 0.6.0

Python-isal is now cross-platform thanks to adding Windows support in this
release.

• python -m gzip's behaviour has been changed since fixing bug:
  bpo-43316 <https://bugs.python.org/issue43316>_. This bug was not present
  in python -m isal.igzip but it handled the error differently than the
  solution in CPython. This is now corrected and python -m isal.igzip
  handles the error the same as the fixed python -m gzip.
• Installation on Windows is now supported. Wheels are provided for Windows as
  well.

Version 0.5.0

• Fix a bug where negative integers were not allowed for the adler32 and
  crc32 functions in isal_zlib.
• Provided stubs (type-hint files) for isal_zlib and _isal modules.
  Package is now tested with mypy to ensure correct type information.
• The command-line interface now reads in blocks of 32K instead of 8K. This
  improves performance by about 6% when compressing and 11% when decompressing.
  A hidden -b flag was added to adjust the buffer size for benchmarks.
• A -c or --stdout flag was added to the CLI interface of isal.igzip.
  This allows it to behave more like the gzip or pigz command line
  interfaces.

Version 0.4.0

• Move wheel building to cibuildwheel on github actions CI. Wheels are now
  provided for Mac OS as well.
• Make a tiny change in setup.py so python-isal can be build on Mac OS X.

Version 0.3.0

• Set included ISA-L library at version 2.30.0.
• Python-isal now comes with a source distribution of ISA-L in its source
  distribution against which python-isal is linked statically upon installation
  by default. Dynamic linking against system libraries is now optional. Wheels
  with the statically linked ISA-L are now provided on PyPI.

Version 0.2.0

• Fixed a bug where writing of the gzip header would crash if an older version
  of Python 3.7 was used such as on Debian or Ubuntu. This is due to
  differences between point releases because of a backported feature. The code
  now checks if the backported feature is present.
• Added Python 3.9 to the testing.
• Fixed setup.py to list setuptools as a requirement.
• Changed homepage to reflect move to pycompression organization.

Version 0.1.0

The first release for python-isal includes a implementation of the igzip module
that is compliant with the tests for CPython's gzip module. The zlib module has
still some issues. This release was made to allow easy installation for people
who want to enjoy the speed improvements of the igzip module over the gzip module.

• Publish API documentation on readthedocs.
• Add API documentation.
• Ensure the igzip module is fully compatible with the gzip stdlib module.
• Add compliance tests from CPython to ensure isal_zlib and igzip are validated
  to the same standards as the zlib and gzip modules.
• Added a working gzip app using python -m isal.igzip
• Add test suite that tests all possible settings for functions on the
  isal_zlib module.
• Create igzip module which implements all gzip functions and methods.
• Create isal_zlib module which implements all zlib functions and methods.
