Description: Introduction
        ------------
        
        ``pyzstd`` module provides classes and functions for compressing and decompressing data, using Facebook's `Zstandard <http://www.zstd.net>`_ (or zstd as short name) algorithm.
        
        The API is similar to Python's bz2/lzma/zlib module.
        
        Includes zstd v1.4.9 source code, can also dynamically link to zstd library provided by system, and has a CFFI implementation that can work with PyPy, see `this note <https://pyzstd.readthedocs.io/en/latest/#build-pyzstd>`_ for details.

        Release note
        ------------
        **0.14.4  (Mar 24, 2021)**
        
        #. Add a CFFI implementation that can work with PyPy.
        
        #. Allow dynamically link to zstd library.
        
        **0.14.3  (Mar 4, 2021)**
        
        Update zstd source code from v1.4.8 to `v1.4.9 <https://github.com/facebook/zstd/releases/tag/v1.4.9>`_.
        
        **0.14.2  (Feb 24, 2021)**
        
        #. Add two convenient functions: `compress_stream() <https://pyzstd.readthedocs.io/en/latest/#compress_stream>`_, `decompress_stream() <https://pyzstd.readthedocs.io/en/latest/#decompress_stream>`_.
        
        #. Some improvements.
        
        **0.14.1  (Dec 19, 2020)**
        
        #. Update zstd source code from v1.4.5 to `v1.4.8 <https://github.com/facebook/zstd/releases/tag/v1.4.8>`_.
        
            * v1.4.6 is a non-public release for Linux kernel.
        
            * v1.4.8 is a hotfix for `v1.4.7 <https://github.com/facebook/zstd/releases/tag/v1.4.7>`_.
        
        #. Some improvements, no API changes.
        
        **0.13.0  (Nov 7, 2020)**
        
        #. ``ZstdDecompressor`` class: now it has the same API and behavior as BZ2Decompressor / LZMADecompressor classes in Python standard library, it stops after a frame is decompressed.
        
        #. Add an ``EndlessZstdDecompressor`` class, it accepts multiple concatenated frames. It is renamed from previous ``ZstdDecompressor`` class, but ``.at_frame_edge`` is ``True`` when both input and output streams are at a frame edge.
        
        #. Rename ``zstd_open()`` function to ``open()``, consistent with Python standard library.
        
        #. ``decompress()`` function:
        
            * ~9% faster when: there is one frame, and the decompressed size was recorded in frame header.
        
            * raises ZstdError when input **or** output data is not at a frame edge. Previously, it only raise for output data is not at a frame edge.
        
        **0.12.5  (Oct 12, 2020)**
        
        No longer use `Argument Clinic <https://docs.python.org/3/howto/clinic.html>`_, now supports Python 3.5+, previously 3.7+.
        
        **0.12.4  (Oct 7, 2020)**
        
        It seems the API is stable.
        
        **0.2.4  (Sep 2, 2020)**
        
        The first version upload to PyPI.
        
        Includes zstd `v1.4.5 <https://github.com/facebook/zstd/releases/tag/v1.4.5>`_ source code.
