3.12.11

Features

• Improved SSL connection handling by changing the default ssl_shutdown_timeout
  from 0.1 to 0 seconds. SSL connections now use Python's default graceful
  shutdown during normal operation but are aborted immediately when the connector
  is closed, providing optimal behavior for both cases. Also added support for
  ssl_shutdown_timeout=0 on all Python versions. Previously, this value was
  rejected on Python 3.11+ and ignored on earlier versions. Non-zero values on
  Python < 3.11 now trigger a RuntimeWarning -- by :user:bdraco.

  The ssl_shutdown_timeout parameter is now deprecated and will be removed in
  aiohttp 4.0 as there is no clear use case for changing the default.
