0.11.9

## Release Notes

Released on 2026-05-04.

_Note due to a [timeout publishing to crates.io](https://github.com/astral-sh/uv/actions/runs/25359185135/job/74362183138), the GitHub portion of this release was published manually by a maintainer using the artifacts built in CI. Consequently, GitHub attestations will not be available. Additionally, this release will not be fully published to crates.io. There should be no other effects._

### Python 3.14.5 release candidate

This release includes a special release candidate for the next Python 3.14 patch release. Python 3.14 included a new garbage collection implementation, which reduced pause times but caused significant unexpected memory pressure in production environments. In 3.14.5 and 3.15, the previous garbage collection implementation will be restored.

We would greatly appreciate if you tested the 3.14.5rc1 version included in this release. The stable version is expected to be released soon and any feedback on potential issues would be helpful to the Python development team.

For more context, see the [announcement](https://discuss.python.org/t/reverting-the-incremental-gc-in-python-3-14-and-3-15/107014), [issue](https://github.com/python/cpython/issues/148726), and [pull request](https://github.com/python/cpython/pull/148720).

## Verifying GitHub Artifact Attestations

The artifacts in this release have attestations generated with GitHub Artifact Attestations. These can be verified by using the [GitHub CLI](https://cli.github.com/manual/gh_attestation_verify):
```sh
gh attestation verify <file-path of downloaded artifact> --repo astral-sh/uv
```

You can also download the attestation from [GitHub](https://github.com/astral-sh/uv/attestations) and verify against that directly:
```sh
gh attestation verify <file-path of downloaded artifact> --bundle <file-path of downloaded attestation>
```
