v0.12.8

Compare Source

Released on 2026-08-31.

Enhancements

• Warn about invalid tool directories and continue upgrading valid tools with uv tool upgrade --all (#​21368)

Preview features

• Deduplicate identical files within and across cached wheels with the content-addressed-cache preview feature (#​21327)
• Reduce allocations while extracting content-addressed wheels by reusing the hashing buffer across files (#​21340)
• Speed up content-addressed cache cleanup on macOS by reading hard-link counts in bulk (#​21344)

Performance

• Prevent concurrent uv processes from downloading and extracting the same remote wheel more than once (#​21379)
• Speed up dependency graph construction from large lockfiles by indexing packages during traversal (#​21373)
• Extend indexed lockfile traversal to exports, dependency trees, audits, and freshness checks (#​21377)
• Speed up warm resolutions by reducing repeated marker interner work (#​21300)

Bug fixes

• Do not trust hashes from direct URLs discovered only in wheel metadata when installing with --require-hashes (#​21348)
• Use a compatible Azure Storage API version for anonymous and authenticated requests, allowing credential retries when public access is disabled (#​21366)
• Redact Azure shared access signature (sig) query parameters from displayed URLs (#​21360)
• Treat projects below one-level workspace member globs as standalone instead of aborting workspace discovery (#​21341)

Other changes

• Update astral-tokio-tar to 0.7.0 and use effective sizes when tracking extracted hard links (#​21346)
