lz4 - Mark stream bindings as experimental

This release relegates the stream bindings to experimental status and disables them in all wheel builds. This was necessary as the test suite was causing build failures on multiple architectures. These bindings are currently in an unmaintained state.

lz4 - Publish wheels for Python 3.9

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 required some significant changes to the Travis and Appveyor configurations including:

Moving to Visual Studio 2019 (14.2) on AppVeyor
Building against the XCode 12.2 image on Travis

lz4 - Enhance support for block decompression with unknown size of decompressed data

This release changes the handling of errors for block decompression when uncompressed_size > 0. In this case, we no longer check that the uncompressed data has exactly the size specified by uncompressed_size: this argument is now used as an upper bound.

In addition, we introduce a new exception: LZ4BlockError which is raised whenever the LZ4 library fails.

These two changes together allow "guessing" of the uncompressed data size: simply set uncompressed_size to a number and try decompress, and catchLZ4BlockError. If LZ4BlockError is raised, increase uncompressed_size and try again.

See the documentation for more details and examples.
