Aiohttp

==================

- Many HTTP proxies has buggy keepalive support. Let's not reuse connection but
close it after processing every response. (`3070 <https://github.com/aio-libs/aiohttp/pull/3070>`_)

- Provide vendor source files in tarball (`3076 <https://github.com/aio-libs/aiohttp/pull/3076>`_)




----

==================

- Fix ``sock_read`` timeout. (`3053 <https://github.com/aio-libs/aiohttp/pull/3053>`_)
- When using a server-request body as the ``data=`` argument of a client request,
iterate over the content with ``readany`` instead of ``readline`` to avoid ``Line
too long`` errors. (`3054 <https://github.com/aio-libs/aiohttp/pull/3054>`_)

==================

Features
--------

- Raise ``ConnectionResetError`` instead of ``CancelledError`` on trying to
write to a closed stream. (`2499 <https://github.com/aio-libs/aiohttp/pull/2499>`_)
- Implement ``ClientTimeout`` class and support socket read timeout. (`2768 <https://github.com/aio-libs/aiohttp/pull/2768>`_)
- Enable logging when ``aiohttp.web`` is used as a program (`2956 <https://github.com/aio-libs/aiohttp/pull/2956>`_)
- Add canonical property to resources (`2968 <https://github.com/aio-libs/aiohttp/pull/2968>`_)
- Forbid reading response BODY after release (`2983 <https://github.com/aio-libs/aiohttp/pull/2983>`_)
- Implement base protocol class to avoid a dependency from internal
``asyncio.streams.FlowControlMixin`` (`2986 <https://github.com/aio-libs/aiohttp/pull/2986>`_)
- Cythonize ``helpers.reify``, 5% boost on macro benchmark (`2995 <https://github.com/aio-libs/aiohttp/pull/2995>`_)
- Optimize HTTP parser (`3015 <https://github.com/aio-libs/aiohttp/pull/3015>`_)
- Implement ``runner.addresses`` property. (`3036 <https://github.com/aio-libs/aiohttp/pull/3036>`_)
- Use ``bytearray`` instead of a list of ``bytes`` in websocket reader. It
improves websocket message reading a little. (`3039 <https://github.com/aio-libs/aiohttp/pull/3039>`_)
- Remove heartbeat on closing connection on keepalive timeout. The used hack
violates HTTP protocol. (`3041 <https://github.com/aio-libs/aiohttp/pull/3041>`_)
- Limit websocket message size on reading to 4 MB by default. (`3045 <https://github.com/aio-libs/aiohttp/pull/3045>`_)


Bugfixes
--------

- Don't reuse a connection with the same URL but different proxy/TLS settings
(`2981 <https://github.com/aio-libs/aiohttp/pull/2981>`_)
- When parsing the Forwarded header, the optional port number is now preserved.
(`3009 <https://github.com/aio-libs/aiohttp/pull/3009>`_)


Improved Documentation
----------------------

- Make Change Log more visible in docs (`3029 <https://github.com/aio-libs/aiohttp/pull/3029>`_)
- Make style and grammar improvements on the FAQ page. (`3030 <https://github.com/aio-libs/aiohttp/pull/3030>`_)
- Document that signal handlers should be async functions since aiohttp 3.0
(`3032 <https://github.com/aio-libs/aiohttp/pull/3032>`_)


Deprecations and Removals
-------------------------

- Deprecate custom application's router. (`3021 <https://github.com/aio-libs/aiohttp/pull/3021>`_)
