+Version History
+===============
+
+0.5.0 (released 2016-11-10)
+---------------------------
+
+* Vendored version of zstd updated to 1.1.1.
+* Continuous integration for Python 3.6 and 3.7
+* Continuous integration for Conda
+* Added compression and decompression APIs providing similar interfaces
+  to the standard library ``zlib`` and ``bz2`` modules. This allows
+  coding to a common interface.
+* ``zstd.__version__` is now defined.
+* ``read_from()`` on various APIs now accepts objects implementing the buffer
+  protocol.
+* ``read_from()`` has gained a ``skip_bytes`` argument. This allows callers
+  to pass in an existing buffer with a header without having to create a
+  slice or a new object.
+* Implemented ``ZstdCompressionDict.as_bytes()``.
+* Python's memory allocator is now used instead of ``malloc()``.
+* Low-level zstd data structures are reused in more instances, cutting down
+  on overhead for certain operations.
+* ``distutils`` boilerplate for obtaining an ``Extension`` instance
+  has now been refactored into a standalone ``setup_zstd.py`` file. This
+  allows other projects with ``setup.py`` files to reuse the
+  ``distutils`` code for this project without copying code.
+* The monolithic ``zstd.c`` file has been split into a header file defining
+  types and separate ``.c`` source files for the implementation.
+
+History of the Project
+======================
+
[phone] - Zstandard 1.0.0 is released and Gregory starts hacking on a
+Python extension for use by the Mercurial project. A very hacky prototype
+is sent to the mercurial-devel list for RFC.
+
[phone] - Most functionality from Zstandard C API implemented. Source
+code published on https://github.com/indygreg/python-zstandard. Travis-CI
+automation configured. 0.0.1 release on PyPI.
+
[phone] - After the API was rounded out a bit and support for Python
+2.6 and 2.7 was added, version 0.1 was released to PyPI.
+
[phone] - After the compressor and decompressor APIs were changed, 0.2
+was released to PyPI.
+
[phone] - 0.3 is released with a bunch of new features. ZstdCompressor
+now accepts arguments controlling frame parameters. The source size can now
+be declared when performing streaming compression. ZstdDecompressor.decompress()
+is implemented. Compression dictionaries are now cached when using the simple
+compression and decompression APIs. Memory size APIs added.
+ZstdCompressor.read_from() and ZstdDecompressor.read_from() have been
+implemented. This rounds out the major compression/decompression APIs planned
+by the author.
+
[phone] - 0.3.3 is released with a bug fix for read_from not fully
+decoding a zstd frame (issue #2).
+
[phone] - 0.4.0 is released with zstd 1.1.0, support for custom read and
+write buffer sizes, and a few bug fixes involving failure to read/write
+all data when buffer sizes were too small to hold remaining data.
+
[phone] - 0.5.0 is released with zstd 1.1.1 and other enhancements.
