Release Notes

This release introduces the uv project, tool, script, and python interfaces. If you've been following uv's development, you've probably seen these new commands behind a preview flag. Now, the interfaces are stable and ready for production-use.

These features are all documented in new, comprehensive documentation.

This release also stabilizes preview functionality in uv venv:

  • uv venv --python <version> will automatically download the Python version if required
  • uv venv will read the required Python version from the .python-version file or pyproject.toml

The uv pip interface should not be affected by any breaking changes.

Note the following changelog entries does not include all the new features since they were added incrementally as preview features. See the feature page in the documentation for a comprehensive listing, or read the blog post for more context on the new features.
