Version 2.11.912

2.11.912 (2024-11-26)

• Improved timeout reliability and performance in asynchronous mode.
• Fixed PyPy discrete background watcher stop condition in synchronous mode when the ConnectionPool isn't closed properly.
• Fixed lack of timeout using default system resolver in asynchronous mode.
• Fixed a rare issue when connection tear down ran into an exception in Windows proactor loop mode. ssltransport is freed before what we initially expected.
• Improved reliability of DNS-over-QUIC, and DNS-over-TLS.

Version 2.11.911

2.11.911 (2024-11-14)

• Improved support for async I/O data reader.
• Fixed non-respect of blocksize when uploading a body in an asynchronous context.

Version 2.11.910

2.11.910 (2024-11-08)

• Improved reliability of reusing a specific outgoing port. The feature is no longer experimental.

Version 2.11.909

2.11.909 (2024-11-07)

• Fixed DNS-over-QUIC, DNS-over-TLS, and DNS-over-UDP(Cleartext) connection procedure on network that lacks IPv6 access.
• Fixed DNS-over-TLS unstable over a slow network.
• Fixed a bug when setting a specific port in source_address and setting happy_eyeballs=True.
  We now silently discard the specific port to avoid a conflict / race condition with OS outgoing port allocation.
• Improved reliability of our tests and fixed warnings in them.
• Preemptively disabled QUIC (HTTP/3 included) with interpreter built with FIPS-compliant SSL module.
  Our QUIC implementation isn't FIPS-compliant for the moment. To force using non-FIPS QUIC implementation,
  please patch urllib3.util.ssl_.IS_FIPS and set it to False.
• Fixed DoQ default certs loading as done in DoT, and DoH.
• Improved reusability of a specific outgoing port. This is still an experimental feature, it is
  likely that CPython have a bug that prevent consistent behavior for this.

Version 2.11.908

2.11.908 (2024-11-03)

• Fixed async connection shutdown in HTTP/1.1 and HTTP/2 leaving a asyncio.TransportSocket and _SelectorSocketTransport partially closed.
• Added automatic mitigation of using deprecated PROTOCOL_TLS_* constants in ssl_version parameter.

Version 2.11.907

2.11.907 (2024-10-30)

• Fixed attempt to send ping frame in our discrete background idle watcher when the connection has just been closed.

Version 2.11.906

2.11.906 (2024-10-26)

• Fixed unexpected exception when recreating a connection using the same outgoing port.
  Add SO_REUSEPORT if available, fallback to SO_REUSEADDR. This socket option
  is not bullet proof against reusability errors. Some OS differs in behaviors.

2.11.905

2.11.905 (2024-10-26)

• Fixed custom loop like uvloop needing advanced error handling on transport close.
• Fixed MacOS connection reset by peer handling to detect connection close (continuation of fix in 2.11.902)

Version 2.11.904

2.11.904 (2024-10-25)

• Improve (async) close procedure when used in a uvloop.

Version 2.11.903

2.11.903 (2024-10-22)

• Fixed (low-level) exception leak when using get_response(...) after urlopen(..., multiplexed=True).
• Fixed erroneous calculated maximal wait when starting a connection upgrade to a higher protocol version in rare cases (async+windows only).
