Changelog for python3-zstandard-0.19.0-lp154.2.1.x86_64.rpm :

* Sun Nov 20 2022 Mia Herkt - Update to 0.19.0 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. gh#indygreg/python-zstandard#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.- No changelog for 0.18.0 available
* Tue Feb 01 2022 Ben Greiner - Correctly test the installed solib- Skip python2 on SLE/Leap: no longer supported
* Sun Jan 30 2022 Sarah Kriesch - update to 0.17.0
* Python 3.9 wheels are now provided.
* Support for Python 3.5 has been dropped.
* Python 3.6 is now the minimum required Python version.
* Bundled zstandard library upgraded from 1.4.5 to 1.5.1.
* The bundled zstandard library is now using the single C source file distribution. The 2 main header files are still present, as these are needed by CFFI to generate the CFFI bindings.
* PyBuffer instances are no longer checked to be C contiguous and have a single dimension. The former was redundant with what PyArg_ParseTuple() already did and the latter is not necessary in practice because very few extension modules create buffers with more than 1 dimension. (#124)
* Added Python typing stub file for the zstandard module. (#120)
* The make_cffi.py script should now respect the CC environment variable for locating the compiler. (#103)
* CI now properly uses the cffi backend when running all tests.
* train_dictionary() has been rewritten to use the fastcover APIs and to consistently call ZDICT_optimizeTrainFromBuffer_fastCover() instead of different C APIs depending on what arguments were passed. The function also now accepts arguments f, split_point, and accel, which are parameters unique to fastcover.
* CI now tests and builds wheels for Python 3.9.
* zstd.c file renamed to c-ext/backend_c.c.
* All built/installed Python modules are now in the zstandard package. Previously, there were modules in other packages. (#115)
* C source code is now automatically formatted with clang-format.
* ZstdCompressor.stream_writer(), ZstdCompressor.stream_reader(), ZstdDecompressor.stream_writer(), and ZstdDecompressor.stream_reader() now accept a closed argument to control whether the underlying stream should be closed when the ZstdCompressionWriter, ZstdCompressReader, ZstdDecompressionWriter, or ZstdDecompressionReader is closed. (#76)
* There is now a zstandard.open() function for returning a file object with zstd (de)compression. (#64)
* The zstandard module now exposes a backend_features attribute containing a set of strings denoting optional features present in that backend. This can be used to sniff feature support by performing a string lookup instead of sniffing for API presence or behavior.
* Python docstrings have been moved from the C backend to the CFFI backend. Sphinx docs have been updated to generate API documentation via the CFFI backend. Documentation for Python APIs is now fully defined via Python docstrings instead of spread across Sphinx ReST files and source code.
* ZstdCompressionParameters now exposes a strategy property.
* There are now compress() and decompress() convenience functions on the zstandard module. These are simply wrappers around the corresponding APIs on ZstdCompressor and ZstdDecompressor.
* The deprecated CompressionParameters type alias to ZstdCompressionParamaters has been removed. Use ZstdCompressionParameters.
* setup.py now recognizes a ZSTD_EXTRA_COMPILER_ARGS environment variable to specify additional compiler arguments to use when compiling the C backend.
* PyPy build and test coverage has been added to CI.
* Added CI jobs for building against external zstd library.
* Wheels supporting macOS ARM/M1 devices are now being produced.
* References to Python 2 have been removed from the in-repo Debian packaging code.
* Significant work has been made on a Rust backend. It is currently feature complete but not yet optimized. We are not yet shipping the backend as part of the distributed wheels until it is more mature.
* ZstdCompressor.multi_compress_to_buffer() and ZstdDecompressor.multi_decompress_to_buffer() are no longer available when linking against a system zstd library. These experimental features are only available when building against the bundled single file zstd C source file distribution. (#106)
* The .pyi type annotations file has replaced various default argument values with ....
* manylinux2014_aarch64 wheels are now being produced for CPython 3.6+. (#145).
* Wheels are now being produced for CPython 3.10.
* Arguments to ZstdCompressor() and ZstdDecompressor() are now all optional in the C backend and an explicit None value is accepted. Before, the C backend wouldn’t accept an explicit None value (but the CFFI backend would). The new behavior should be consistent between the backends. (#153)
* The C backend now exposes the symbols ZstdCompressionReader, ZstdCompressionWriter, ZstdDecompressionReader, and ZstdDecompressionWriter. This should match the behavior of the CFFI backend. (#165)
* ZstdCompressionWriter and ZstdDecompressionWriter now implement __iter__ and __next__, which always raise io.UnsupportedOperation.
* Documentation on thread safety has been updated to note that derived objects like ZstdCompressionWriter have the same thread unsafety as the contexts they were derived from. (#166)
* The HASHLOG3_MAX constant has been removed since it is no longer defined in zstd 1.5.1.
* Tue Jul 21 2020 Marketa Calabkova - update to 0.14.0
* This will likely be the final version supporting Python 2.7. Future releases will likely only work on Python 3.5+. See #109 for more context.
* There is a significant possibility that future versions will use Rust - instead of C - for compiled code. See #110 for more context.
* Some internal fields of C structs are now explicitly initialized. (Possible fix for #105.)
* The ``make_cffi.py`` script used to build the CFFI bindings now calls ``distutils.sysconfig.customize_compiler()`` so compiler customizations (such as honoring the ``CC`` environment variable) are performed. Patch by AATTArfrever. (#103)
* The ``make_cffi.py`` script now sets ``LC_ALL=C`` when invoking the preprocessor in an attempt to normalize output to ASCII. (#95)
* Mon Mar 09 2020 pgajdosAATTsuse.com- version update to 0.13.0
* ``pytest-xdist`` ``pytest`` extension is now installed so tests can be run in parallel.
* CI now builds ``manylinux2010`` and ``manylinux2014`` binary wheels instead of a mix of ``manylinux2010`` and ``manylinux1``.
* Official support for Python 3.8 has been added.
* Bundled zstandard library upgraded from 1.4.3 to 1.4.4.
* Python code has been reformatted with black.

* Fix memory leak in ZstdDecompressionReader.seek() (#82).
* CI transitioned to Azure Pipelines (from AppVeyor and Travis CI).
* Switched to pytest for running tests (from nose).
* Fri May 24 2019 Tomáš Chvátal - Update to 0.11.1:
