Our review
Pros
  • Derives version bumps from Conventional Commits and API-breaking-change checks
  • Supports Cargo workspaces and changelog generation with git-cliff
  • Creates releases on GitHub, Gitea, or GitLab and publishes to Cargo registries
  • Derives version increments from parsed commit messages
  • Builds changelogs, stamps files, and runs a configured build command

  • Requires commit messages that work with the selected parser
  • Self-hosted setup puts installation and CI/CD configuration on your team
  • Its published artifact focus is Python distributions and configured upload files
