Fixed the default encoding of chunked request bodies to be UTF-8 instead of ISO-8859-1.
All other methods of supplying a request body already use UTF-8 starting in urllib3 v2.0. (#3053 <https://github.com/urllib3/urllib3/issues/3053>__)
Fixed ResourceWarning on CONNECT with Python < 3.11.4 by backporting https://github.com/python/cpython/issues/103472. (#3252 <https://github.com/urllib3/urllib3/issues/3252>__)
Adjust tolerance for floating-point comparison on Windows to avoid flakiness in CI (#3413 <https://github.com/urllib3/urllib3/issues/3413>__)
Fixed a crash where certain standard library hash functions were absent in restricted environments. (#3432 <https://github.com/urllib3/urllib3/issues/3432>__)
Fixed mypy error when adding to HTTPConnection.default_socket_options. (#3448 <https://github.com/urllib3/urllib3/issues/3448>__)

HTTP/2 (experimental)

HTTP/2 support is still in early development.

Excluded Transfer-Encoding: chunked from HTTP/2 request body (#3425 <https://github.com/urllib3/urllib3/issues/3425>__)
Added version checking for h2 (https://pypi.org/project/h2/) usage.

Now only accepting supported h2 major version 4.x.x. (#3290 <https://github.com/urllib3/urllib3/issues/3290>__)
Added a probing mechanism for determining whether a given target origin
supports HTTP/2 via ALPN. (#3301 <https://github.com/urllib3/urllib3/issues/3301>__)
Add support for sending a request body with HTTP/2 (#3302 <https://github.com/urllib3/urllib3/issues/3302>__)

Deprecations and Removals

Note for downstream distributors: the _version.py file has been removed and is now created at build time by hatch-vcs. (#3412 <https://github.com/urllib3/urllib3/issues/3412>__)
Drop support for end-of-life PyPy3.8 and PyPy3.9. (#3475 <https://github.com/urllib3/urllib3/issues/3475>__)
