v0.5.17

Compare Source

This release includes support for generating lockfiles from scripts based on inline metadata, as defined in PEP 723.

By default, scripts remain unlocked, and must be locked explicitly with uv lock --script /path/to/script.py, which
will generate a lockfile adjacent to the script (e.g., script.py.lock). Once generated, the lockfile will be
respected (and updated, if necessary) across uv run --script, uv add --script, and uv remove --script invocations.

This release also includes support for uv export --script and uv tree --script. Both commands support PEP 723
scripts with and without accompanying lockfiles.

• Add --script support to uv tree for PEP 723 scripts (#​10159)
• Add ls alias to uv {tool, python, pip} list (#​10240)
• Allow reading --with-requirements from stdin in uv add and uv run (#​10447)
• Warn-and-ignore for unsupported requirements.txt options (#​10420)

Preview features

• Add remaining Python type annotations to build backend (#​10434)
