Release Notes

Released on 2026-09-01.

Python

• Add CPython 3.15.0rc2 (#21413, #21415)

Enhancements

• Add --no-locked and --no-frozen to disable lock modes enabled by UV_LOCKED and UV_FROZEN for a single invocation (#21408)
• Report the exact command-line lock-mode flag in warnings and errors (#21402)

Performance

• Speed up cold wheel installs by extracting each streaming ZIP archive in a single blocking task and reusing buffers across files (#21372)

Bug fixes

• Update async_http_range_reader to 0.11.1 to address a potential memory-safety issue when reading metadata ranges from untrusted wheels (#21401)
• Remove sensitive headers when redirects cross authentication realms, including same-host redirects that change URL schemes (#21382)
• Redact secrets in signed URLs from retry diagnostics, including nested request errors (#21381)
• Give --locked, --frozen, --check, and --check-exists precedence over conflicting UV_LOCKED and UV_FROZEN values (#21396)
• Prevent concurrent uv processes from redundantly extracting the same local or source-built wheel (#21400)

0.12.8

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)

✅ Devin Review: No Issues Found

Devin Review analyzed this PR and found no bugs or issues to report.

[seonghobae]

Superseded by Draft #333 after exact inheritance verification. #333 is based on current dependency root #233, reproduces this PR's Dockerfile payload byte-for-byte (resulting blob 3d22cb90ddcbd6907ce2708f3f46069b353421de, identical to #327) and adds the missing repository-owned immutable uv 0.12.9 tag+digest regression with explicit RED 726a0631... -> GREEN f598a8f4... lineage. No #327 production delta is dropped. Closing this bot PR removes duplicate ownership; #333 remains Draft until fresh exact-head/current-base gates and predecessor integration are satisfied.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
