+Changes

+
+* Stop attempting to package Python 3.6 for Miniconda. The latest version of
+ Miniconda is using Python 3.7. The Python 3.6 Miniconda packages were a lie
+ since this were built against Python 3.7.
+* ``ZstdCompressor.stream_reader()``'s and ``ZstdDecompressor.stream_reader()``'s
+ ``closed`` attribute is now a read-only property instead of a method. This now
+ properly matches the ``IOBase`` API and allows instances to be used in more
+ places that accept ``IOBase`` instances.
+
+0.10.0 (released 2018-10-08)
+============================
+
+Backwards Compatibility Notes
+-----------------------------
+
+* ``ZstdDecompressor.stream_reader().read()`` now consistently requires an
+ argument in both the C and CFFI backends. Before, the CFFI implementation
+ would assume a default value of ``-1``, which was later rejected.
+* The ``compress_literals`` argument and attribute has been removed from
+ ``zstd.ZstdCompressionParameters`` because it was removed by the zstd 1.3.5
+ API.
+* ``ZSTD_CCtx_setParametersUsingCCtxParams()`` is no longer called on every
+ operation performed against ``ZstdCompressor`` instances. The reason for this
+ change is that the zstd 1.3.5 API no longer allows this without calling
+ ``ZSTD_CCtx_resetParameters()`` first. But if we called
+ ``ZSTD_CCtx_resetParameters()`` on every operation, we'd have to redo
+ potentially expensive setup when using dictionaries. We now call
+ ``ZSTD_CCtx_reset()`` on every operation and don't attempt to change
+ compression parameters.
+* Objects returned by ``ZstdCompressor.stream_reader()`` no longer need to be
+ used as a context manager. The context manager interface still exists and its
+ behavior is unchanged.
+* Objects returned by ``ZstdDecompressor.stream_reader()`` no longer need to be
+ used as a context manager. The context manager interface still exists and its
+ behavior is unchanged.
+
+Bug Fixes
+---------
+
+* ``ZstdDecompressor.decompressobj().decompress()`` should now return all data
+ from internal buffers in more scenarios. Before, it was possible for data to
+ remain in internal buffers. This data would be emitted on a subsequent call
+ to ``decompress()``. The overall output stream would still be valid. But if
+ callers were expecting input data to exactly map to output data (say the
+ producer had used ``flush(COMPRESSOBJ_FLUSH_BLOCK)`` and was attempting to
+ map input chunks to output chunks), then the previous behavior would be
+ wrong. The new behavior is such that output from
+ ``flush(COMPRESSOBJ_FLUSH_BLOCK)`` fed into ``decompressobj().decompress()``
+ should produce all available compressed input.
+* ``ZstdDecompressor.stream_reader().read()`` should no longer segfault after
+ a previous context manager resulted in error (#56).
+* ``ZstdCompressor.compressobj().flush(COMPRESSOBJ_FLUSH_BLOCK)`` now returns
+ all data necessary to flush a block. Before, it was possible for the
+ ``flush()`` to not emit all data necessary to fully represent a block. This
+ would mean decompressors wouldn't be able to decompress all data that had been
+ fed into the compressor and ``flush()``ed. (#55).
+
+New Features
+------------
+
+* New module constants ``BLOCKSIZELOG_MAX``, ``BLOCKSIZE_MAX``,
+ ``TARGETLENGTH_MAX`` that expose constants from libzstd.
+* New ``ZstdCompressor.chunker()`` API for manually feeding data into a
+ compressor and emitting chunks of a fixed size. Like ``compressobj()``, the
+ API doesn't impose restrictions on the input or output types for the
+ data streams. Unlike ``compressobj()``, it ensures output chunks are of a
+ fixed size. This makes this API useful when the compressed output is being
+ fed into an I/O layer, where uniform write sizes are useful.
+* ``ZstdCompressor.stream_reader()`` no longer needs to be used as a context
+ manager (#34).
+* ``ZstdDecompressor.stream_reader()`` no longer needs to be used as a context
+ manager (#34).
+* Bundled zstandard library upgraded from 1.3.4 to 1.3.6.

+-------

+* Upgrade various packages used in CI to latest versions. Notably tox (in
