Release Notes

astral-sh/uv (uv)

v0.12.13

Compare Source

Released on 2026-09-10.

Python

• Add GraalPy 3.13.0 (#​21431)

Enhancements

• Verify hashes when downloading PEP 658 metadata sidecars (#​21563)

Preview features

• Respect ty exclusions when uv check automatically selects members of a virtual workspace (#​21555)

Performance

• Avoid full wheel downloads during resolution by reusing supported hashes from direct URL fragments when metadata is available separately (#​21279)

Bug fixes

• Edit Windows entry-point launcher resources in memory to support Nano Server and reduce antivirus contention (#​18713)
• Prefer core-metadata over legacy aliases in JSON index responses (#​21563)

v0.12.12

Compare Source

Released on 2026-09-09.

The executables in our macOS and Windows release archives and uv and uv_build wheels are now code-signed. macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables verification of the release publisher and binary integrity, supports publisher-based allowlisting, and should reduce security warnings and antivirus false positives.

Bug fixes

• Exclude distributions uploaded after the exclude-newer cutoff from lockfiles and generated requirement hashes (#​21539)

v0.12.11

Compare Source

Released on 2026-09-08.

Preview features

• Generate missing artifact hashes when exporting pylock.toml files to ensure they conform to PEP 751 (#​20146)
• Warn when pylock.toml artifact hash tables are empty, which will be rejected in a future uv release (#​21462)

Performance

• Speed up installs that overwrite existing files by eliminating per-file temporary directories for atomic hard-link, symlink, and reflink replacements (#​21478)
• Speed up installs that merge copied wheels into existing environments by replacing per-file temporary directories with adjacent temporary files (#​21468)
• Speed up local wheel installs by replacing the shared ZIP cursor lock with positioned reads (#​21500)
• Speed up local wheel installs by reusing ZIP readers and buffers across extracted files (#​21499)
• Avoid transitive dependency checks and unnecessary resolution when uv pip install --no-deps finds the requested packages already installed (#​21523)

Bug fixes

• Verify source archives against hashes recorded in uv.lock before reading their metadata or running their build backends (#​21223)
• Verify supplied hashes for registry requirements pinned with === under both --verify-hashes and --require-hashes (#​21543)
• Apply hashes from public-version pins to matching local versions when no exact local-version hash is provided (#​21544)
• Support PowerShell virtual environment activation from UNC paths, including WSL paths (#​19159)
• Trim surrounding whitespace from entries in .python-version and .python-versions files (#​21529)
• Suppress VIRTUAL_ENV mismatch warnings for uv add --no-sync, uv remove --no-sync, and uv add --frozen (#​21496)
• Warn and continue when uv python list cannot query an interpreter (#​21498)

Documentation

• Restore TOML syntax highlighting for exclude-newer examples (#​21534)

v0.12.10

Compare Source

Released on 2026-09-04.

Enhancements

• Attempt to revoke short-lived PyPI trusted-publishing tokens after uv publish completes, including when publishing fails (#​21423)

Preview features

• Omit exclude-newer-package settings for packages outside the resolution from uv.lock with the missing-exclude-newer-package-lock preview feature (#​21455)
• Show terminal dependency cycles in uv tree --invert output (#​21404)

Performance

• Speed up locking large workspaces with conflicts by excluding unrelated extras and dependency groups from conflict simplification (#​21399)
• Speed up uv publish by hashing each artifact in a single blocking task and reusing the buffer across reads (#​21389)

Bug fixes

• Prevent --locked from failing when exclude-newer-package settings differ only for packages outside the resolution (#​21454)
• Allow uv lock --check to reuse a lockfile when an absolute exclude-newer cutoff is moved later (#​19571)
• Allow uv lock --check to reuse a lockfile when a package-specific exclude-newer cutoff is disabled (#​21450)
• Require an explicit --name when uv init would infer a project name reserved for a Python interpreter (#​21395)
• Write package-specific exclude-newer cutoffs to uv.lock in a deterministic order (#​21453)

v0.12.9

Compare Source

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)

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
