Release Notes

urllib3/urllib3

v1.26.8

Compare Source

• Added extra message to urllib3.exceptions.ProxyError when urllib3 detects that a proxy is configured to use HTTPS but the proxy itself appears to only use HTTP.
• Added a mention of the size of the connection pool when discarding a connection due to the pool being full.
• Added explicit support for Python 3.11.
• Deprecated the Retry.MAX_BACKOFF class property in favor of Retry.DEFAULT_MAX_BACKOFF to better match the rest of the default parameter names. Retry.MAX_BACKOFF is removed in v2.0.
• Changed location of the vendored ssl.match_hostname function from urllib3.packages.ssl_match_hostname to urllib3.util.ssl_match_hostname to ensure Python 3.10+ compatibility after being repackaged by downstream distributors.
• Fixed absolute imports, all imports are now relative.

v1.26.7

Compare Source

===================

• Fixed a bug with HTTPS hostname verification involving IP addresses and lack of SNI. (Issue #​2400)
• Fixed a bug where IPv6 braces weren't stripped during certificate hostname matching. (Issue #​2240)

v1.26.6

Compare Source

===================

• Deprecated the urllib3.contrib.ntlmpool module. urllib3 is not able to support it properly due to reasons listed in this issue <https://github.com/urllib3/urllib3/issues/2282>_. If you are a user of this module please leave a comment.
• Changed HTTPConnection.request_chunked() to not erroneously emit multiple Transfer-Encoding headers in the case that one is already specified.
