+- 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.
