Release Notes

astral-sh/setup-uv (astral-sh/setup-uv)

v6.4.3: 🌈 fix relative paths starting with dots

Compare Source

🐛 Bug fixes

• fix relative paths starting with dots @​eifinger (#​500)

v6.4.2: 🌈 Interpret relative inputs as under working-directory

Compare Source

Changes

This release will interpret relative paths in inputs as relative
to the value of working-directory (default is ${{ github.workspace }}) .
This means the following configuration

- uses: astral-sh/setup-uv@v6
   with:
     working-directory: /my/path
     cache-dependency-glob: uv.lock

will look for the cache-dependency-glob under /my/path/uv.lock

🐛 Bug fixes

• interpret relative inputs as under working-directory @​eifinger (#​498)

🧰 Maintenance

• chore: update known versions for 0.8.1/0.8.2 @​github-actions[bot] (#​497)
• chore: update known versions for 0.8.0 @​github-actions[bot] (#​491)

v0.8.9

Compare Source

Enhancements

• Add --reinstall flag to uv python upgrade (#​15194)

Bug fixes

• Include build settings in cache key for registry source distribution lookups (#​15225)
• Avoid creating bin links on uv python upgrade if they don't already exist (#​15192)
• Respect system proxies on macOS and Windows (#​15221)

Documentation

• Add the 3.14 classifier (#​15187)

v0.8.8

Compare Source

Bug fixes

• Fix find_uv_bin compatibility with Python <3.10 (#​15177)

v0.8.7

Compare Source

Python

• On Mac/Linux, libtcl, libtk, and _tkinter are built as separate shared objects, which fixes matplotlib's tkagg backend (the default on Linux), Pillow's PIL.ImageTk library, and other extension modules that need to use libtcl/libtk directly.
• Tix is no longer provided on Linux. This is a deprecated Tk extension that appears to have been previously broken.

See the python-build-standalone release notes for details.

Enhancements

• Do not update uv.lock when using --isolated (#​15154)
• Add support for --prefix and --with installations in find_uv_bin (#​14184)
• Add support for discovering base prefix installations in find_uv_bin (#​14181)
• Improve error messages in find_uv_bin (#​14182)
• Warn when two packages write to the same module (#​13437)

Preview features

• Add support for package-level conflicts in workspaces (#​14906)

Configuration

• Add UV_DEV and UV_NO_DEV environment variables (for --dev and --no-dev) (#​15010)

Bug fixes

• Fix regression where --require-hashes applied to build dependencies in uv pip install (#​15153)
• Ignore GraalPy devtags (#​15013)
• Include all site packages directories in ephemeral environment overlays (#​15121)
• Search in the user scheme scripts directory last in find_uv_bin (#​14191)

Documentation

• Add missing periods (.) to list elements in Features docs page (#​15138)

v0.8.6

Compare Source

This release contains hardening measures to address differentials in behavior between uv and Python's built-in ZIP parser (CVE-2025-54368).

Prior to this release, attackers could construct ZIP files that would be extracted differently by pip, uv, and other tools. As a result, ZIPs could be constructed that would be considered harmless by (e.g.) scanners, but contain a malicious payload when extracted by uv. As of v0.8.6, uv now applies additional checks to reject such ZIPs.

Thanks to a triage effort with the Python Security Response Team and PyPI maintainers, we were able to determine that these differentials were not exploited via PyPI during the time they were present. The PyPI team has also implemented similar checks and now guards against these parsing differentials on upload.

Although the practical risk of exploitation is low, we take the hypothetical risk of parser differentials very seriously. Out of an abundance of caution, we have assigned this advisory a CVE identifier and have given it a "moderate" severity suggestion.

These changes have been validated against the top 15,000 PyPI packages; however, it's plausible that a non-malicious ZIP could be falsely rejected with this additional hardening. As an escape hatch, users who do encounter breaking changes can enable UV_INSECURE_NO_ZIP_VALIDATION to restore the previous behavior. If you encounter such a rejection, please file an issue in uv and to the upstream package.
