uv 0.13.1 - Fast Python Package Manager

uv is an extremely fast Python package and project manager written in Rust. It is designed as a single tool to replace multiple standard utilities, including pip, pip-tools, pipx, poetry, pyenv, twine, and virtualenv workflows. This software is ideal for developers who need to manage Python environments and dependencies with high performance and efficiency. By consolidating these tools into one binary, uv streamlines the development process for Python projects of all sizes.

Key features:

• Written in Rust for extreme speed and performance.
• Replaces pip, pip-tools, pipx, poetry, pyenv, twine, and virtualenv.
• Supports Linux SPARC architecture with fallback mechanisms.
• Includes CPython 3.16.0a1 support.
• Optimized binary size and reduced metadata parsing overhead.
• Enhanced error reporting for missing trusted hashes.
• Safe uninstallation processes that prevent deletion of unrelated files.
