v3.1.10
Add skip existing when publishing to PyPi
v3.1.9
Revert to using created release events
v3.1.8
Update github actions trigger to use published release
v3.1.7
Update github actions trigger
v3.1.6
Trigger github actions on a release being made.
v3.1.5
Remove the push requirement for triggering PyPi pushes of artifacts.
v3.1.4
Shift wheel building to github actions
Disable Travis and Appveyor building
Disable Windows wheel builds which are failing with memory allocation problems with 64 bit on the github actions runners
Disable Aarch64 builds which are failing somewhere in the stream bindings tests
LZ4FrameFile.write()/LZ4FrameDecompressor.decompress() handle buffer protocol correctly
Pass source_size kwarg through from frame.open to LZ4FrameFile instance
Add readall to LZ4FrameFile and use it on python 3.10
v3.1.3:
This release adds support for publishing wheels to PyPi for Python 3.9. Wheel building is currently broken for Python 3.9 on Arm/Aarch64.
This release also drops building of wheels for Python 3.5.
v3.0.2:
This release removes py3c from the codebase and strips out unused Python 2 support code. No functional changes are included with this release.
v3.0.1:
This release fixes an issue that prevented the OSX wheels from being published to PyPi, and contains no functional changes.
v3.0.0:
This release:
* Drops support for Python 2 (although some dead code remains for future removal)
* Adds streams support thanks to the hard work of @tSed
* Fixes a performance bug with the frame bindings - thanks to @bjonen for the careful report and reproducer
* Adds Python 3.8 support
v2.2.1:
Update the bundled LZ4 library to version 1.9.1
This release updates the bundled LZ4 library to version 1.9.1.
The 2.2.x releases will be the final release that support Python 2.7. In the near future we'll begin work on the 3.0.x release which will only support Python >= 3.5, and will require LZ4 > 1.9.0.
v2.2.0:
Add more detail to the install section of docs
2.1.5
This release contains no functional changes other than changes to the Appveyor configuration for publishing wheels.
2.1.4
This release contains no functional changes other than changes to the Travis configuration for publishing wheels.
2.1.3
A simplification of the tox.ini file
More robust checking for pkgconfig availability
Integration of cibuildwheel into travis builds so as to build and publish binary wheels for Linux and OSX
Only require pytest-runner if pytest/test is being called
Blacklists version 3.3.0 of pytest which has a bug that can cause the tests to fail.
2.1.2:
Improves the speed of importing the module by avoiding the use of pkg_resources
Fixes some flake8 warnings
Resolves a small issue with the test suite when detecting memory usage increases
2.0.1:
This release fixes: tests failed when run under python setup.py test, but passed when running under tox.
2.0.0:
It's now possible to specify a compession dictionary for block compression.
The bundled LZ4 libraries have been updated to 1.8.2
A compatibility fix for 2.x memoryview objects has been added.
Various flake8 cleanups and test additions.
1.1.0:
This release removes the deprecated functions which were marked as remove in 1.0, but nonetheless remained:
lz4.lz4version()
LZ4FrameCompressor.finalize()
As a side effect, we noo longer have a dependency on the deprecation package.
0.23.2:
Fixes an error in the deprecated LZ4Compressor.finalize() method
Improves documentation
Has all example code in documentation verified via doctest
0.19.1:
This release adds compressed file handling capability to the lz4.frame sub-package.
This necessitated some changes to the API of lz4.frame.decompress_chunk, ad some smaller changes to the LZ4FrameCompressor and LZ4FrameDecompressor classes. Please see updated documentation for further details.
0.18.2:
This release fixes a memory leak that was introduced in lz4.frame.decompress in 0.18.1. This leak resulted from an incorrect ref count on the returned result which prevented it from ever being released and garbage collected.
0.18.1:
This is a minor bugfix release which fixes two small bugs which would result in source references not being released on error conditions in lz4.frame.compress.
0.18.0:
This release changes the strategy for allocating memory to not use undocumented and potentially fragile Python internals (Py_SIZE). This may have a small performance impact, but brings stronger guarantees for future stability.
0.17.0:
This release fixes a pathological case where compressing and decompressing a zero length bytes object could result in the resulting bytes object causing False to be returned from val == 'b'.
This release brings
Huge changes to the LZ4 Frame support which should now be considered beta quality
A new pytest based test harness, and significantly re-worked testing
An end to Python 2.6 support - no testing is currently done against Python 2.6 although the code probably does still work with Python 2.6 at this point in time.
py-lz4 provides Python bindings for the LZ4 compression library by Yann
Collet.
At this time the project contains bindings for the LZ4 block format,
which are considered stable.
Support for the LZ4 frame format is a work-in-progress and available as a
technology preview. A future relase will implement support for the LZ4
stream format.
