3.8.4 (2023-02-12)
Bugfixes
- Fixed incorrectly overwriting cookies with the same name and domain, but different path. #6638
- Fixed
ConnectionResetErrornot being raised after client disconnection in SSL environments. #7180
3.8.3 (2022-09-21)
Attention!
This is the last :doc:`aiohttp <index>` release tested under Python 3.6. The 3.9 stream is dropping it from the CI and the distribution package metadata.
Bugfixes
Increased the upper boundary of the :doc:`multidict:index` dependency to allow for the version 6 -- by :user:`hugovk`.
It used to be limited below version 7 in :doc:`aiohttp <index>` v3.8.1 but was lowered in v3.8.2 via :pr:`6550` and never brought back, causing problems with dependency pins when upgrading. :doc:`aiohttp <index>` v3.8.3 fixes that by recovering the original boundary of
< 7. #6950
3.8.2 (2022-09-20, subsequently yanked on 2022-09-21)
Bugfixes
Support registering OPTIONS HTTP method handlers via RouteTableDef. #4663

Remove a deprecated usage of pytest.warns(None) #6663
Fix regression where
asyncio.CancelledErroroccurs on client disconnection. #6719Export :py:class:`~aiohttp.web.PrefixedSubAppResource` under :py:mod:`aiohttp.web` -- by :user:`Dreamsorcerer`.
This fixes a regression introduced by :pr:`3469`. #6889
Dropped the :class:`object` type possibility from the :py:attr:`aiohttp.ClientSession.timeout` property return type declaration. #6917, #6923
Improved Documentation

Misc
3.8.1 (2021-11-14)
Bugfixes
- 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 an index out of range error in aiohttp. For example, if user compile CPython with --disable-ipv6 option, but his system enable the ipv6. #5901
- Do not install "examples" as a top-level package. #6189
- Restored ability to connect IPv6-only host. #6195

3.8.0 (2021-10-31)
Features
Added a
GunicornWebWorkerfeature for extending the aiohttp server configuration by allowing the 'wsgi' coroutine to returnweb.AppRunnerobject. #2988Switch from
http-parsertollhttp#3561Use Brotli instead of brotlipy #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
Make access log use local time with timezone #3853
Implemented
readuntilinStreamResponse#4054FileResponse now supports ETag. #4594
Add a request handler type alias
aiohttp.typedefs.Handler. #4686AioHTTPTestCaseis 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. #4700Add validation of HTTP header keys and values to prevent header injection. #4818
Add predicate to
AbstractCookieJar.clear. AddAbstractCookieJar.clear_domainto clean all domain and subdomains cookies only. #4942Add keepalive_timeout parameter to web.run_app. #5094
Tracing for client sent headers #5105
Make type hints for http parser stricter #5267
Add final declarations for constants. #5275
Switch to external frozenlist and aiosignal libraries. #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
Always create a new event loop in
aiohttp.web.run_app(). This adds better compatibility withasyncio.run()or if trying to run multiple apps in sequence. #5572Add
aiohttp.pytest_plugin.AiohttpClientfor static typing of pytest plugin. #5585Added a
socket_factoryargument toBaseTestServer. #5844Add compression strategy parameter to enable_compression method. #5909
Added support for Python 3.10 to Github Actions CI/CD workflows and fix the related deprecation warnings -- :user:`Hanaasagi`. #5927
Switched
chardettocharset-normalizerfor guessing the HTTP payload body encoding -- :user:`Ousret`. #5930Added optional auto_decompress argument for HttpRequestParser #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
Added
base_urlparameter to the initializer of :class:`~aiohttp.ClientSession`. #6013Add Trove classifier and create binary wheels for 3.10. -- :user:`hugovk`. #6079
Started shipping platform-specific wheels with the
musltag targeting typical Alpine Linux runtimes — :user:`asvetlov`. #6139Started shipping platform-specific arm64 wheels for Apple Silicon — :user:`asvetlov`. #6139

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
- Removed the deprecated
loopargument from theasyncio.sleep/gathercalls #5905 - Return

(SECURITY BUG) Started preventing open redirects in the

Fix interpretation difference of the pure-Python and the Cython-based HTTP parsers construct a
yarl.URLobject for HTTP request-target.Before this fix, the Python parser would turn the URI's absolute-path for

Fix connecting to link-local IPv6 addresses. #4554
Fix a problem with connection waiters that are never awaited. #4562
Always make sure transport is not closing before reuse a connection.
Reuse a protocol based on keepalive in headers is unreliable. For example, uWSGI will not support keepalive even it serves a HTTP 1.1 request, except explicitly configure uWSGI with a
--http-keepaliveoption.Servers designed like uWSGI could cause aiohttp intermittently raise a ConnectionResetException when the protocol poll runs out and some protocol is reused. #4587

This behavior should prevent clients from being unable to use PUT/POST methods on endpoints that are redirected because of a trailing slash. #3579
Drop the processed task from
all_tasks()list early. It prevents logging about a task with unhandled exception when the server is used in conjunction withasyncio.run(). #3587Signaltype annotation changed fromSignal[Callable[['TraceConfig'], Awaitable[None]]]toSignal[Callable[ClientSession, SimpleNamespace, ...]. #3595Use sanitized URL as Location header in redirects #3614
Improve typing annotations for multipart.py along with changes required by mypy in files that references multipart.py. #3621
