Release Notes

Released on 2026-07-07.

Security

This release updates our ZIP library, astral-async-zip, to v0.0.20, which includes 15 changes that harden our ZIP handling against parser differentials. uv may reject ZIP archives with malformed or ambiguous content that were previously accepted.

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:

gh attestation verify <file-path of downloaded artifact> --repo astral-sh/uv

You can also download the attestation from GitHub and verify against that directly:

gh attestation verify <file-path of downloaded artifact> --bundle <file-path of downloaded attestation>
