aiohttp 3.10.9

on Python PyPI

Bug fixes

• Fixed proxy headers being used in the ConnectionKey hash when a proxy was not being used -- by :user:bdraco.

  If default headers are used, they are also used for proxy headers. This could have led to creating connections that were not needed when one was already available.

• Widened the type of the trace_request_ctx parameter of
  :meth:ClientSession.request() <aiohttp.ClientSession.request> and friends
  -- by :user:layday.

Removals and backward incompatible breaking changes

• Fixed failure to try next host after single-host connection timeout -- by :user:brettdh.

  The default client :class:aiohttp.ClientTimeout params has changed to include a sock_connect timeout of 30 seconds so that this correct behavior happens by default.
