Cmux Release

Handles the full cmux release workflow from version bumping to GitHub tag creation. You get changelog updates pulled from commits, automated version script execution, and a pretag guard that catches build number issues before they break Sparkle auto-updates. The `/release` command does the heavy lifting, but you can also run the scripts manually if needed. Most useful when you're shipping a new minor version and want the changelog, version files, and DMG asset generation handled in one shot. The guard script alone is worth having around since mismatched build numbers will silently break the updater.

cmux Release

Prefer the /release command. It determines the new version (minor by default), gathers the Changelog line from each PR merged since the last stable tag, updates CHANGELOG.md, runs ./scripts/bump-version.sh, commits, runs ./scripts/release-pretag-guard.sh, then tags and pushes.

Changelog source

Feature PRs don't edit CHANGELOG.md. Each PR description has a ## Changelog section with one user-facing line (Added, Changed, Fixed, or Removed, present tense) or none. At release time, /release step 2 fetches every PR merged since the last v* tag in one GraphQL query and classifies it with references/changelog-lines.jq:
