===================
- Use errors.HttpProcessingError.message as HTTP error reason and
message (`459 <https://github.com/aio-libs/aiohttp/pull/459>`_)
- Optimize cythonized multidict a bit
- Change repr's of multidicts and multidict views
- default headers in ClientSession are now case-insensitive
- Make '=' char and 'wss://' schema safe in urls (`477 <https://github.com/aio-libs/aiohttp/pull/477>`_)
- `ClientResponse.close()` forces connection closing by default from now (`479 <https://github.com/aio-libs/aiohttp/pull/479>`_)
N.B. Backward incompatible change: was `.close(force=False) Using
`force` parameter for the method is deprecated: use `.release()`
instead.
- Properly requote URL's path (`480 <https://github.com/aio-libs/aiohttp/pull/480>`_)
- add `skip_auto_headers` parameter for client API (`486 <https://github.com/aio-libs/aiohttp/pull/486>`_)
- Properly parse URL path in aiohttp.web.Request (`489 <https://github.com/aio-libs/aiohttp/pull/489>`_)
- Raise RuntimeError when chunked enabled and HTTP is 1.0 (`488 <https://github.com/aio-libs/aiohttp/pull/488>`_)
- Fix a bug with processing io.BytesIO as data parameter for client API (`500 <https://github.com/aio-libs/aiohttp/pull/500>`_)
- Skip auto-generation of Content-Type header (`507 <https://github.com/aio-libs/aiohttp/pull/507>`_)
- Use sendfile facility for static file handling (`503 <https://github.com/aio-libs/aiohttp/pull/503>`_)
- Default `response_factory` in `app.router.add_static` now is
`StreamResponse`, not `None`. The functionality is not changed if
default is not specified.
- Drop `ClientResponse.message` attribute, it was always implementation detail.
- Streams are optimized for speed and mostly memory in case of a big
HTTP message sizes (`496 <https://github.com/aio-libs/aiohttp/pull/496>`_)
- Fix a bug for server-side cookies for dropping cookie and setting it
again without Max-Age parameter.
- Don't trim redirect URL in client API (`499 <https://github.com/aio-libs/aiohttp/pull/499>`_)
- Extend precision of access log "D" to milliseconds (`527 <https://github.com/aio-libs/aiohttp/pull/527>`_)
- Deprecate `StreamResponse.start()` method in favor of
`StreamResponse.prepare()` coroutine (`525 <https://github.com/aio-libs/aiohttp/pull/525>`_)
`.start()` is still supported but responses begun with `.start()`
does not call signal for response preparing to be sent.
- Add `StreamReader.__repr__`
- Drop Python 3.3 support, from now minimal required version is Python
3.4.1 (`541 <https://github.com/aio-libs/aiohttp/pull/541>`_)
- Add `async with` support for `ClientSession.request()` and family (`536 <https://github.com/aio-libs/aiohttp/pull/536>`_)
- Ignore message body on 204 and 304 responses (`505 <https://github.com/aio-libs/aiohttp/pull/505>`_)
- `TCPConnector` processed both IPv4 and IPv6 by default (`559 <https://github.com/aio-libs/aiohttp/pull/559>`_)
- Add `.routes()` view for urldispatcher (`519 <https://github.com/aio-libs/aiohttp/pull/519>`_)
- Route name should be a valid identifier name from now (`567 <https://github.com/aio-libs/aiohttp/pull/567>`_)
- Implement server signals (`562 <https://github.com/aio-libs/aiohttp/pull/562>`_)
- Drop a year-old deprecated *files* parameter from client API.
- Added `async for` support for aiohttp stream (`542 <https://github.com/aio-libs/aiohttp/pull/542>`_)
