- Update to 2.2.3:
* Features
+ Added support for Python 3.13.
* Bugfixes
+ 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.
+ Fixed ResourceWarning on CONNECT with Python < 3.11.4 by backporting
python/cpython#103472.
+ Fixed a crash where certain standard library hash functions were absent
in restricted environments.
+ Added the Proxy-Authorization header to the list of headers to strip
from requests when redirecting to a different host. As before,
different headers can be set via Retry.remove_headers_on_redirect.
+ Allowed passing negative integers as amt to read methods of
http.client.HTTPResponse as an alternative to None.
+ Fixed issue where InsecureRequestWarning was emitted for HTTPS
connections when using Emscripten.
+ Fixed HTTPConnectionPool.urlopen to stop automatically casting
non-proxy headers to HTTPHeaderDict. This change was premature as it
did not apply to proxy headers and HTTPHeaderDict does not handle byte
header values correctly yet.
+ Changed InvalidChunkLength to ProtocolError when response terminates
before the chunk length is sent.
+ Changed ProtocolError to be more verbose on incomplete reads with
excess content.
+ Added support for HTTPResponse.read1() method.
+ Fixed issue where requests against urls with trailing dots were
failing due to SSL errors when using proxy.
+ Fixed HTTPConnection.proxy_is_verified and
