==================
- Added support for experimental `async-tokio` event loop written in Rust
https://github.com/PyO3/tokio
- Write to transport ``\r\n`` before closing after keepalive timeout,
otherwise client can not detect socket disconnection. (`1883 <https://github.com/aio-libs/aiohttp/pull/1883>`_)
- Only call `loop.close` in `run_app` if the user did *not* supply a loop.
Useful for allowing clients to specify their own cleanup before closing the
asyncio loop if they wish to tightly control loop behavior
- Content disposition with semicolon in filename (`917 <https://github.com/aio-libs/aiohttp/pull/917>`_)
- Added `request_info` to response object and `ClientResponseError`. (`1733 <https://github.com/aio-libs/aiohttp/pull/1733>`_)
- Added `history` to `ClientResponseError`. (`1741 <https://github.com/aio-libs/aiohttp/pull/1741>`_)
- Allow to disable redirect url re-quoting (`1474 <https://github.com/aio-libs/aiohttp/pull/1474>`_)
- Handle RuntimeError from transport (`1790 <https://github.com/aio-libs/aiohttp/pull/1790>`_)
- Dropped "%O" in access logger (`1673 <https://github.com/aio-libs/aiohttp/pull/1673>`_)
- Added `args` and `kwargs` to `unittest_run_loop`. Useful with other
decorators, for example `patch`. (`1803 <https://github.com/aio-libs/aiohttp/pull/1803>`_)
- Added `iter_chunks` to response.content object. (`1805 <https://github.com/aio-libs/aiohttp/pull/1805>`_)
- Avoid creating TimerContext when there is no timeout to allow
compatibility with Tornado. (`1817 <https://github.com/aio-libs/aiohttp/pull/1817>`_) (`#1180 <https://github.com/aio-libs/aiohttp/pull/1180>`_)
- Add `proxy_from_env` to `ClientRequest` to read from environment
variables. (`1791 <https://github.com/aio-libs/aiohttp/pull/1791>`_)
- Add DummyCookieJar helper. (`1830 <https://github.com/aio-libs/aiohttp/pull/1830>`_)
- Fix assertion errors in Python 3.4 from noop helper. (`1847 <https://github.com/aio-libs/aiohttp/pull/1847>`_)
- Do not unquote `+` in match_info values (`1816 <https://github.com/aio-libs/aiohttp/pull/1816>`_)
- Use Forwarded, X-Forwarded-Scheme and X-Forwarded-Host for better scheme and
host resolution. (`1134 <https://github.com/aio-libs/aiohttp/pull/1134>`_)
- Fix sub-application middlewares resolution order (`1853 <https://github.com/aio-libs/aiohttp/pull/1853>`_)
- Fix applications comparison (`1866 <https://github.com/aio-libs/aiohttp/pull/1866>`_)
- Fix static location in index when prefix is used (`1662 <https://github.com/aio-libs/aiohttp/pull/1662>`_)
- Make test server more reliable (`1896 <https://github.com/aio-libs/aiohttp/pull/1896>`_)
- Extend list of web exceptions, add HTTPUnprocessableEntity,
HTTPFailedDependency, HTTPInsufficientStorage status codes (`1920 <https://github.com/aio-libs/aiohttp/pull/1920>`_)
