Update dependency uv to v0.12.10 - #213

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)
