Zanie Blue 287faaf92c Move Rust and Python version support out of the Platform support policy (#18535)
The content is unchanged.

I'm planning to expand the content in the Python version and Platform
support files and generally don't like that these are mixed.

Platform support

uv has Tier 1 support for the following platforms:

  • macOS (Apple Silicon)
  • macOS (x86_64)
  • Linux (x86_64)
  • Windows (x86_64)

uv is continuously built, tested, and developed against its Tier 1 platforms. Inspired by the Rust project, Tier 1 can be thought of as "guaranteed to work".

uv has Tier 2 support ("guaranteed to build") for the following platforms:

  • Linux (PPC64LE)
  • Linux (RISC-V64)
  • Linux (aarch64)
  • Linux (armv7)
  • Linux (i686)
  • Linux (s390x)
  • Windows (arm64)

uv has Tier 3 support ("best effort") for the following platforms:

  • FreeBSD (x86_64)
  • Windows (i686)

uv provides official binaries on GitHub and pre-built wheels on PyPI for its Tier 1 and Tier 2 platforms.

Tier 2 platforms are continuously built, but the uv test suite is not run on them and stability may vary in practice.

Tier 3 platforms may not be built or tested, but uv will accept patches to fix bugs.

Windows versions

The minimum supported Windows versions are Windows 10 and Windows Server 2016, following Rust's own Tier 1 support.

macOS versions

uv supports macOS 13+ (Ventura).

uv is known to work on macOS 12, but requires installation of a realpath executable.
