Changelog

Sourced from uvicorn's changelog.

0.51.0 (July 8, 2026)

0.50.2 (July 6, 2026)

Oh I just realized we'll have to pause dependabot while #16256 is in flight becuase bumps to the pyproject toml wont' be reflected in the uv migration so the bump will get lost. I'll pause dependabot until after we can get it merged.

[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.
