0.12.18

Release Notes

Released on 2026-09-22.

This release addresses GHSA-2cv4-cqwr-gwf7, which is a path traversal weakness during wheel installation on Windows. No other platforms are affected by this advisory.

Enhancements

• Add --output-format json to uv pip install and uv pip sync, including for --dry-run and --check (#21893)
• Add --check to uv pip install and uv pip sync to report planned changes without modifying the environment (#21844)
• Identify failures from get_requires_for_build_* hooks correctly in build errors (#21881)

Preview features

• Validate build requirements for uv build --no-build-isolation with --preview-features build-dependency-check; use --skip-dependency-check to opt out (#21880)

Performance

• Speed up uv_build editable wheel creation by omitting compression from temporary wheels (#21918)

Bug fixes

• Select package versions with wheels compatible with each Python resolution fork, correctly interpreting generic and stable-ABI wheel tags (#21835, #21836)
• Restore project, script, and lock files when uv add, uv remove, or uv version fails or is interrupted (#21860, #21856)
• Use configured dependency-metadata when checking whether installed requirements are satisfied (#21843)
• Reject archive entries that normalize to absolute Windows paths (#21923)
• Recognize distribution filenames and archive extensions when URL fragments contain ? (#21920)
• Generate correctly lowercased platform tags for BSD and Haiku releases (#21853)
• Avoid rebuilding a Windows relative path into an absolute form (#21923)
