feature patch

uv 0.12.13 is now available, introducing support for GraalPy 3.13.0, expanding its compatibility within the Python ecosystem. This patch release enhances security by verifying hashes for PEP 658 metadata sidecars and improves performance by reusing hashes during wheel resolution. It also includes bug fixes for Windows entry-point launchers and JSON index responses, alongside preview updates for `uv check` workspace functionality. Python developers using `uv` will benefit from improved integrity, faster dependency resolution, and broader Python runtime support.

  • →Add GraalPy 3.13.0
  • →Respect ty exclusions when uv check automatically selects members of a virtual workspace
  • →Verify hashes when downloading PEP 658 metadata sidecars
  • →Avoid full wheel downloads during resolution by reusing supported hashes from direct URL fragments when metadata is available separately
  • →Edit Windows entry-point launcher resources in memory to support Nano Server and reduce antivirus contention
