v3.5.0
e13ed99

It is the latest feature release in 3.5 line.
Next big release will be 4.0 (while 3.5.X bugfix releases are possible).

The main new feature is full mypy compliance in strict mode (no unspecialized generic, no untyped definitions etc.)
The next very important thing that users need to know on the road of transition from 3.X to 4.X lines is: 4.X will remove some functionality deprecated in 3.5.
Please make sure that your code doesn't emit any warning with aiohttp 3.5 to reduce the pain of upgrading to future 4.0 (or maybe eliminate it at all).

This is the full list of aiohttp 3.5 changes:

Features

  • The library type annotations are checked in strict mode now.

  • Add support for setting cookies for individual request (#2387 <https://github.com/aio-libs/aiohttp/pull/2387>_)

  • Application.add_domain implementation (#2809 <https://github.com/aio-libs/aiohttp/pull/2809>_)

  • The default app in the request returned by test_utils.make_mocked_request
    can now have objects assigned to it and retrieved using the [] operator. (#3174 <https://github.com/aio-libs/aiohttp/pull/3174>_)

  • Make request.url accessible when transport is closed. (#3177 <https://github.com/aio-libs/aiohttp/pull/3177>_)

  • Add zlib_executor_size argument to Response constructor to allow compression to run in a background executor to avoid blocking the main thread and potentially triggering health check failures. (#3205 <https://github.com/aio-libs/aiohttp/pull/3205>_)

  • Enable users to set ClientTimeout in aiohttp.request (#3213 <https://github.com/aio-libs/aiohttp/pull/3213>_)

  • Don't raise a warning if NETRC environment variable is not set and ~/.netrc file
    doesn't exist. (#3267 <https://github.com/aio-libs/aiohttp/pull/3267>_)

  • Add default logging handler to web.run_app

    If the Application.debug flag is set and the default logger aiohttp.access is used, access logs will now be output using a stderr StreamHandler if no handlers are attached. Furthermore, if the default logger has no log level set, the log level will be set to DEBUG. (#3324 <https://github.com/aio-libs/aiohttp/pull/3324>_)

  • Add method argument to session.ws_connect().

    Sometimes server API requires a different HTTP method for WebSocket connection establishment.

    For example, Docker exec needs POST. (#3378 <https://github.com/aio-libs/aiohttp/pull/3378>_)

  • Create a task per request handling. (#3406 <https://github.com/aio-libs/aiohttp/pull/3406>_)

    constructor. (#3207 <https://github.com/aio-libs/aiohttp/pull/3207>_)

  • Ensure Host header is added first to ClientRequest to better replicate browser (#3265 <https://github.com/aio-libs/aiohttp/pull/3265>_)
  • Fix forward compatibility with Python 3.8: importing ABCs directly from the collections module will not be supported anymore. (#3273 <https://github.com/aio-libs/aiohttp/pull/3273>_)
