### Enhancements

- Accept uppercase release suffixes in wheel platform tags ([#22113](https://github.com/astral-sh/uv/pull/22113))
- Record workspace-member default groups in lockfiles ([#22010](https://github.com/astral-sh/uv/pull/22010), [#22103](https://github.com/astral-sh/uv/pull/22103))
- Record workspace-member dependency-group Python requirements in lockfiles ([#22044](https://github.com/astral-sh/uv/pull/22044), [#22103](https://github.com/astral-sh/uv/pull/22103))
- Record default groups for non-project workspace roots in lockfiles ([#22104](https://github.com/astral-sh/uv/pull/22104))
- Record dependency-group Python requirements for non-project workspace roots in lockfiles ([#22104](https://github.com/astral-sh/uv/pull/22104))
- Format URLs and paths consistently in CLI messages ([#21937](https://github.com/astral-sh/uv/pull/21937))
- Hide the unsupported `--offline` option from `uv publish` help ([#22124](https://github.com/astral-sh/uv/pull/22124))

### Preview features

- Honor `--no-default-groups` in `uv audit` ([#22090](https://github.com/astral-sh/uv/pull/22090))
- Report a clear error when `uv audit` or `uv tool audit` runs offline and hide the unsupported option from help ([#22114](https://github.com/astral-sh/uv/pull/22114))

### Configuration

- Add `UV_PYTHON_ARCH` to select an interpreter architecture independently of its Python version ([#22098](https://github.com/astral-sh/uv/pull/22098))

### Performance

- Reduce uv's binary size by compressing embedded Python download metadata ([#22126](https://github.com/astral-sh/uv/pull/22126))

### Bug fixes

- Verify unchanged requirements against existing lockfile hashes when relocking ([#22083](https://github.com/astral-sh/uv/pull/22083))
- Honor dependency-group Python requirements at non-project workspace roots ([#22101](https://github.com/astral-sh/uv/pull/22101))
- Use each selected workspace member's recorded default groups during frozen sync ([#22015](https://github.com/astral-sh/uv/pull/22015))
- Avoid false entry-point warnings for required workspace members ([#22112](https://github.com/astral-sh/uv/pull/22112))

### Other changes

- Raise the minimum supported Rust version for building uv to 1.97 and update the toolchain to Rust 1.99 ([#22121](https://github.com/astral-sh/uv/pull/22121))

## 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>
```
