Release Notes

The uv build backend is now stable, and considered ready for production use.

The uv build backend is a great choice for pure Python projects. It has reasonable defaults, with the goal of requiring zero configuration for most users, but provides flexible configuration to accommodate most Python project structures. It integrates tightly with uv, to improve messaging and user experience. It validates project metadata and structures, preventing common mistakes. And, finally, it's very fast — uv sync on a new project (from uv init) is 10-30x faster than with other build backends.

To use uv as a build backend in an existing project, add uv_build to the [build-system] section in your pyproject.toml:

[build-system]
requires = ["uv_build>=0.7.19,<0.8.0"]
build-backend = "uv_build"

In a future release, it will replace hatchling as the default in uv init. As before, uv will remain compatible with all standards-compliant build backends.

Python

• Add PGO distributions of Python for aarch64 Linux, which are more optimized for better performance

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

Enhancements

• Ignore Python patch version for --universal pip compile (#14405)
• Update the tilde version specifier warning to include more context (#14335)
• Clarify behavior and hint on tool install when no executables are available (#14423)

Bug fixes

• Make project and interpreter lock acquisition non-fatal (#14404)
• Includes sys.prefix in cached environment keys to avoid --with collisions across projects (#14403)

Documentation

• Add a migration guide from pip to uv projects (#12382)

Python

• Added arm64 Windows Python 3.11, 3.12, 3.13, and 3.14

  These are not downloaded by default, since x86-64 Python has broader ecosystem support on Windows. However, they can be requested with cpython-<version>-windows-aarch64.

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