Release Notes

v3.0.1

Compare Source

Fixed

• To avoid uv configuration interference with the project that is being built, the installation of our own tools is now ran in a different directory. Additionally, UV_EXCLUDE_NEWER is unset. #​240

v3.0.0

Security

• Given the increase and supply-chain attacks and advancements in tooling (for example, pinact or GitHub's Dependabot), this action will stop force-tagging minor and micro releases. This means, there will be no @v3 or @v3.0 tag that gets updated and force-pushed with each update. Always tag with the full version and commit hash; use Zizmor to secure your actions if you can.

Changed

• Only updates of actions and build dependencies, notably including Twine 7 that adds support for packaging metadata 2.5 and PEP 794 – Import Name Metadata.
