Version 2.12.909

2.12.909 (2024-01-20)

• Fixed compatibility with upstream urllib3 when third party program invoke deprecated HTTPResponse.getheader or
  HTTPResponse.getheaders. Those methods were planned to be removed in 2.1 (they still have a pending deprecation
  that mention 2.1 target in the 2.3 version). As such we immediately restore the methods. (#203)
• Implemented our copy of HTTPResponse.read1 heavily simplified as we do already support HTTPResponse.read(-1).
  Also mirrored in AsyncHTTPResponse.read1.
• Automatically grab qh3 for X86/i686 based processors (e.g. win32).
• Fixed the aggressive exception in our native websocket implementation when a server responded positively to an upgrade
  request without the required http header. Instead of RuntimeError, now raises ProtocolError.
