aiohttp 3.5.1 bugfix release

Changes

• Fix a regression about ClientSession._requote_redirect_url modification in debug
  mode.

aiohttp 3.5.0 release

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>_)
