Hyper

------------------

*Minor Changes*

- Support for HTTP/2 draft 15, and 16. No drop of support for draft 14.
- Updated bundled certificate file.

*Bugfixes*

- Fixed ``AttributeError`` being raised when a PING frame was received, thanks
to t2y. (`Issue 79`_)
- Fixed bug where large frames could be incorrectly truncated by the buffered
socket implementation, thanks to t2y. (`Issue 80`_)

*Regressions and Known Bugs*

- Support for Python 3.3 has been temporarily dropped due to features missing
from the Python 3.3 ``ssl`` module. PyOpenSSL has been identified as a
replacement, but until NPN support is merged it cannot be used. Python 3.3
support *will* be re-added when a suitable release of PyOpenSSL is shipped.
- Technically this release also includes support for PyPy and Python 2.7. That
support is also blocked behind a suitable PyOpenSSL release.

For more information on these regressions, please see `Issue 37`_.

*Major Changes*

- Support for HPACK draft 9.
- Support for HTTP/2 draft 14.
- Support for Sever Push, thanks to alekstorm. (`Issue 40`_)
- Use a buffered socket to avoid unnecessary syscalls. (`Issue 56`_)
- If `nghttp2`_ is present, use its HPACK encoder for improved speed and
compression efficiency. (`Issue 60`_)
- Add ``HTTP20Response.gettrailer()`` and ``HTTP20Response.gettrailers()``,
supporting downloading and examining HTTP trailers. (Discussed in part in
`Issue 71`_.)

*Bugfixes*

- ``HTTP20Response`` objects are context managers. (`Issue 24`_)
- Pluggable window managers are now correctly informed about the document size.
(`Issue 26`_)
- Header blocks can no longer be corrupted if read in a different order to the
one in which they were sent. (`Issue 39`_)
- Default window manager is now smarter about sending WINDOWUPDATE frames.
(`Issue 41`_ and `Issue 52`_)
- Fixed inverted window sizes. (`Issue 27`_)
- Correct reply to PING frames. (`Issue 48`_)
- Made the wheel universal, befitting a pure-Python package. (`Issue 46`_)
- HPACK encoder correctly encodes header sets with duplicate headers.
(`Issue 50`_)

------------------

- Add logic for pluggable objects to manage the flow-control window for both
connections and streams.
- Raise new ``HPACKDecodingError`` when we're unable to validly map a
Huffman-encoded string.
- Correctly respect the HPACK EOS character.

------------------

- Use bundled SSL certificates in addition to the OS ones, which have limited
platform availability. (`Issue 9`_)
- Connection objects reset to their basic state when they're closed, enabling
them to be reused. Note that they may not be reused if exceptions are thrown
when they're in use: you must open a new connection in that situation.
- Connection objects are now context managers. (`Issue 13`_)
- The ``HTTP20Adapter`` correctly reuses connections.
- Stop sending WINDOWUPDATE frames with a zero-size window increment.
- Provide basic functionality for gracelessly closing streams.
- Exhausted streams are now disposed of. (`Issue 14`_)

------------------

- Implemented logging. (`Issue 12`_)
- Stopped HTTP/2.0 special headers appearing in the response headers.
(`Issue 16`_)
- `HTTP20Connection` objects are now context managers. (`Issue 13`_)
- Response bodies are automatically decompressed. (`Issue 20`_)
- Provide a requests transport adapter. (`Issue 19`_)
- Fix the build status indicator. (`Issue 22`_)
