### Release Notes

<details>
<summary>urllib3/urllib3 (urllib3)</summary>

###
[`v2.2.1`](https://togithub.com/urllib3/urllib3/blob/HEAD/CHANGES.rst#221-2024-02-16)

[Compare
Source](https://togithub.com/urllib3/urllib3/compare/2.2.0...2.2.1)

\==================

- Fixed issue where `InsecureRequestWarning` was emitted for HTTPS
connections when using Emscripten. (`#&#8203;3331
<https://github.com/urllib3/urllib3/issues/3331>`\__)
- 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. (`#&#8203;3343
<https://github.com/urllib3/urllib3/issues/3343>`\__)
- Changed `ProtocolError` to `InvalidChunkLength` when response
terminates before the chunk length is sent. (`#&#8203;2860
<https://github.com/urllib3/urllib3/issues/2860>`\__)
- Changed `ProtocolError` to be more verbose on incomplete reads with
excess content. (`#&#8203;3261
<https://github.com/urllib3/urllib3/issues/3261>`\__)
