Release Notes

astral-sh/uv (ghcr.io/astral-sh/uv)

v0.12

Released on 2026-08-13.

Enhancements

• Prefer post-quantum key exchange and enable opt-in TLS diagnostics (#​21054)
• Accept whitespace before versions in noncompliant wildcard comparisons such as Requires-Python: >= 3.5.* (#​21012)
• Report a specific error when a PEP 723 closing tag contains trailing whitespace or other content (#​20944)
• Omit source-span carets from diagnostics for empty PEP 508 requirements (#​21094)

Preview features

• Add uv check --no-install-project and respect UV_NO_INSTALL_PROJECT to install dependencies without building or installing the project (#​21085)
• Make the ty subprocess invoked by uv check honor uv's color and progress settings, including quiet mode (#​21086)

Performance

• Speed up resolutions with long runs of unavailable package versions by coalescing gaps in the resolver's version ranges (#​20804)
• Speed up Simple API parsing by deserializing PyPI and Pyx file metadata directly (#​21041)

Bug fixes

• Use windowed pythonw.exe launchers for virtual environments created from managed Python minor-version links (#​19235)
• Allow uv lock to proceed when .venv is an unusable project environment (#​21068)
• Respect fork-strategy when ordering forks created from environments or existing lockfile resolution-markers (#​21000)
• Preserve consecutive wildcard Python minor-version exclusions such as !=3.11.*, !=3.12.* in uv.lock (#​21045)
• Preserve inline comments on the final item in dependency arrays when uv add updates it (#​21008)
• Recover from stale base-interpreter cache metadata when an existing virtual environment exposes a version mismatch (#​21073)
• Prevent interpreter cache reuse across different PYTHONEXECUTABLE and __PYVENV_LAUNCHER__ overrides (#​21075)
• Show standard styling, usage guidance, and line termination for invalid uv version --bump values (#​21076)
