Release notes

Sourced from uvicorn's releases.

Version 0.52.3

Changed

• Update zttp to 0.0.24 and use its combined receive path, improving HTTP/1.1 request parsing performance (#3067)

Full Changelog: Kludex/uvicorn@0.52.2...0.52.3

Version 0.52.2

Fixed

• Update zttp to 0.0.22, fixing bodyless request receives and improving HTTP/1 request parsing performance (#3063)

Full Changelog: Kludex/uvicorn@0.52.1...0.52.2

Version 0.52.1

Fixed

• Complete the closing handshake on server-initiated WebSocket closes in the websockets-sansio and wsproto implementations, waiting for the client's close reply with a 10 second timeout instead of resetting the connection (#3053)

• Handle connection loss while a WebSocket write is waiting on backpressure (#3050)
• Remove duplicate Content-Type and Content-Length headers from WebSocket denial responses on the websockets-sansio implementation, and deliver non-UTF-8 denial bodies intact (#3041)

Superseded by #294, which bumps uvicorn[standard] to 0.52.3 along with a regenerated lockfile (this PR only changed pyproject.toml, which wouldn't have taken effect against the --require-hashes install).

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
