==================
Features
--------
- Added a ``GunicornWebWorker`` feature for extending the aiohttp server configuration by allowing the 'wsgi' coroutine to return ``web.AppRunner`` object.
`2988 <https://github.com/aio-libs/aiohttp/issues/2988>`_
- Switch from ``http-parser`` to ``llhttp``
`3561 <https://github.com/aio-libs/aiohttp/issues/3561>`_
- Use Brotli instead of brotlipy
`3803 <https://github.com/aio-libs/aiohttp/issues/3803>`_
- Disable implicit switch-back to pure python mode. The build fails loudly if aiohttp
cannot be compiled with C Accelerators. Use AIOHTTP_NO_EXTENSIONS=1 to explicitly
disable C Extensions complication and switch to Pure-Python mode. Note that Pure-Python
mode is significantly slower than compiled one.
`3828 <https://github.com/aio-libs/aiohttp/issues/3828>`_
- Make access log use local time with timezone
`3853 <https://github.com/aio-libs/aiohttp/issues/3853>`_
- Implemented ``readuntil`` in ``StreamResponse``
`4054 <https://github.com/aio-libs/aiohttp/issues/4054>`_
- FileResponse now supports ETag.
`4594 <https://github.com/aio-libs/aiohttp/issues/4594>`_
- Add a request handler type alias ``aiohttp.typedefs.Handler``.
`4686 <https://github.com/aio-libs/aiohttp/issues/4686>`_
- ``AioHTTPTestCase`` is more async friendly now.
For people who use unittest and are used to use :py:exc:`~unittest.TestCase`
it will be easier to write new test cases like the sync version of the :py:exc:`~unittest.TestCase` class,
without using the decorator `unittest_run_loop`, just `async def test_*`.
The only difference is that for the people using python3.7 and below a new dependency is needed, it is ``asynctestcase``.
`4700 <https://github.com/aio-libs/aiohttp/issues/4700>`_
- Add validation of HTTP header keys and values to prevent header injection.
`4818 <https://github.com/aio-libs/aiohttp/issues/4818>`_
- Add predicate to ``AbstractCookieJar.clear``.
Add ``AbstractCookieJar.clear_domain`` to clean all domain and subdomains cookies only.
`4942 <https://github.com/aio-libs/aiohttp/issues/4942>`_
- Add keepalive_timeout parameter to web.run_app.
`5094 <https://github.com/aio-libs/aiohttp/issues/5094>`_
- Tracing for client sent headers
`5105 <https://github.com/aio-libs/aiohttp/issues/5105>`_
- Make type hints for http parser stricter
`5267 <https://github.com/aio-libs/aiohttp/issues/5267>`_
- Add final declarations for constants.
`5275 <https://github.com/aio-libs/aiohttp/issues/5275>`_
- Switch to external frozenlist and aiosignal libraries.
`5293 <https://github.com/aio-libs/aiohttp/issues/5293>`_
- Don't send secure cookies by insecure transports.
By default, the transport is secure if https or wss scheme is used.
Use `CookieJar(treat_as_secure_origin="http://127.0.0.1")` to override the default security checker.
`5571 <https://github.com/aio-libs/aiohttp/issues/5571>`_
- Always create a new event loop in ``aiohttp.web.run_app()``.
This adds better compatibility with ``asyncio.run()`` or if trying to run multiple apps in sequence.
`5572 <https://github.com/aio-libs/aiohttp/issues/5572>`_
- Add ``aiohttp.pytest_plugin.AiohttpClient`` for static typing of pytest plugin.
`5585 <https://github.com/aio-libs/aiohttp/issues/5585>`_
- Added a ``socket_factory`` argument to ``BaseTestServer``.
`5844 <https://github.com/aio-libs/aiohttp/issues/5844>`_
- Add compression strategy parameter to enable_compression method.
`5909 <https://github.com/aio-libs/aiohttp/issues/5909>`_
- Added support for Python 3.10 to Github Actions CI/CD workflows and fix the related deprecation warnings -- :user:`Hanaasagi`.
`5927 <https://github.com/aio-libs/aiohttp/issues/5927>`_

`5930 <https://github.com/aio-libs/aiohttp/issues/5930>`_
- Added optional auto_decompress argument for HttpRequestParser
`5957 <https://github.com/aio-libs/aiohttp/issues/5957>`_
- Added support for HTTPS proxies to the extent CPython's
:py:mod:`asyncio` supports it -- by :user:`bmbouter`,
:user:`jborean93` and :user:`webknjaz`.
`5992 <https://github.com/aio-libs/aiohttp/issues/5992>`_
- Added ``base_url`` parameter to the initializer of :class:`~aiohttp.ClientSession`.
`6013 <https://github.com/aio-libs/aiohttp/issues/6013>`_
- Add Trove classifier and create binary wheels for 3.10. -- :user:`hugovk`.
`6079 <https://github.com/aio-libs/aiohttp/issues/6079>`_
- Started shipping platform-specific wheels with the ``musl`` tag targeting typical Alpine Linux runtimes — :user:`asvetlov`.
`6139 <https://github.com/aio-libs/aiohttp/issues/6139>`_
- Started shipping platform-specific arm64 wheels for Apple Silicon — :user:`asvetlov`.
`6139 <https://github.com/aio-libs/aiohttp/issues/6139>`_

- StaticResource prefixes no longer match URLs with a non-folder prefix. For example ``routes.static('/foo', '/foo')`` no longer matches the URL ``/foobar``. Previously, this would attempt to load the file ``/foo/ar``.
`5250 <https://github.com/aio-libs/aiohttp/issues/5250>`_
- Acquire the connection before running traces to prevent race condition.
`5259 <https://github.com/aio-libs/aiohttp/issues/5259>`_

descriptors for the ``tempfile.Temporaryfile``-created
``_io.BufferedRandom`` instances of files sent within multipart request
bodies via HTTP POST requests -- by :user:`webknjaz`.
`5494 <https://github.com/aio-libs/aiohttp/issues/5494>`_

`5868 <https://github.com/aio-libs/aiohttp/issues/5868>`_
- Uses :py:class:`~asyncio.ThreadedChildWatcher` under POSIX to allow setting up test loop in non-main thread.
`5877 <https://github.com/aio-libs/aiohttp/issues/5877>`_
- Fix the error in handling the return value of `getaddrinfo`.
`getaddrinfo` will return an `(int, bytes)` tuple, if CPython could not handle the address family.
It will cause a index out of range error in aiohttp. For example, if user compile CPython with
`--disable-ipv6` option but his system enable the ipv6.
`5901 <https://github.com/aio-libs/aiohttp/issues/5901>`_

`5925 <https://github.com/aio-libs/aiohttp/issues/5925>`_
- Fix resetting `SIGCHLD` signals in Gunicorn aiohttp Worker to fix `subprocesses` that capture output having an incorrect `returncode`.
`6130 <https://github.com/aio-libs/aiohttp/issues/6130>`_
- Raise ``400: Content-Length can't be present with Transfer-Encoding`` if both ``Content-Length`` and ``Transfer-Encoding`` are sent by peer by both C and Python implementations
`6182 <https://github.com/aio-libs/aiohttp/issues/6182>`_
Improved Documentation
----------------------
- Refactored OpenAPI/Swagger aiohttp addons, added ``aio-openapi``
`5326 <https://github.com/aio-libs/aiohttp/issues/5326>`_
- Fixed docs on request cookies type, so it matches what is actually used in the code (a
read-only dictionary-like object).
`5725 <https://github.com/aio-libs/aiohttp/issues/5725>`_
- Documented that the HTTP client ``Authorization`` header is removed
on redirects to a different host or protocol.
