0.12.4

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)

• 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)

Copilot fix failing CI/CD checks

Fixed in 3e6cca2. CI failed because agent-framework-lab:dev still pinned uv==0.11.32 while the root workspace moved to 0.12.5, making the workspace unresolvable. Updated python/packages/lab/pyproject.toml and python/uv.lock (uv package entry + both specifiers); uv lock --check with uv 0.12.5 now passes with no drift.

Conflicts resolved in b0916ea. Merged origin/main; conflicts were in python/packages/lab/pyproject.toml and python/uv.lock, both caused by main's ruff 0.16.0 → 0.16.3 bump landing on the same lines. Kept main's ruff==0.16.3/mypy==2.3.1 and this PR's uv==0.12.5, and rebased the uv entries onto main's lockfile. uv lock --check with uv 0.12.5 passes, and the net diff vs main is now only the uv bump.
