🔖 Release 2.3.901

[Ousret]

2.3.901 (2023-11-26)

• Small performance improvement while in HTTP/1.1
• Any string passed down to the body will enforce a default Content-Type: text/plain; charset=utf-8 for safety, unless
  you specified a Content-Type header yourself. The charset parameter will always be set to utf-8.
  It is recommended that you pass bytes instead of a plain string. If a conflicting charset has been set that
  does not refer to utf-8, a warning will be raised.
• Added callable argument in urlopen, and request named on_upload_body that enables you to track
  body upload progress for a single request. It takes 4 positional arguments, namely:
  (total_sent: int, total_to_be_sent: int | None, is_completed: bool, any_error: bool)
  total_to_be_sent may be set to None if we're unable to know in advance the total size (blind iterator/generator).
• Fixed a rare case where ProtocolError was raised instead of expected IncompleteRead exception.
• Improved HTTP/3 overall performance.
• Changed the default max connection per host for (http, https) pools managed by PoolManager.
  If the PoolManager is instantiated with num_pools=10, each (managed) subsequent pool will have maxsize=10.
• Improved performance in a multithreading context while using many multiplexed connections.
• Changed the default max saturated multiplexed connections to 64 as the minimum.
  Now a warning will be fired if you reach the maximum capacity of stored saturated multiplexed connections.
