cmux release workflow, version bumping, changelog updates, pretag guard, release tags, and release asset expectations. Use when preparing or troubleshooting a cmux release.

cmux Release

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

The docs changelog page at web/app/[locale]/(landing)/docs/changelog/page.tsx renders from CHANGELOG.md, so there is no separate docs changelog source to update.

Version bumping

./scripts/bump-version.sh          # minor (0.15.0 -> 0.16.0)
./scripts/bump-version.sh patch    # 0.15.0 -> 0.15.1
./scripts/bump-version.sh major    # 0.15.0 -> 1.0.0
./scripts/bump-version.sh 1.0.0    # explicit version

This updates MARKETING_VERSION and CURRENT_PROJECT_VERSION. The build number auto-increments and must increase for Sparkle auto-update to work. Bump the minor version unless explicitly asked otherwise.

Tagging

./scripts/release-pretag-guard.sh
git tag vX.Y.Z
git push origin vX.Y.Z
gh run watch --repo manaflow-ai/cmux

If the pretag guard fails, run ./scripts/bump-version.sh, commit the build-number bump, then retry.

Release artifacts and secrets

  • The release asset is cmux-macos.dmg, attached to the tag. The README download button points to releases/latest/download/cmux-macos.dmg.
  • Signing and notarization require the GitHub secrets APPLE_CERTIFICATE_BASE64, APPLE_CERTIFICATE_PASSWORD, APPLE_SIGNING_IDENTITY, APPLE_ID, APPLE_APP_SPECIFIC_PASSWORD, APPLE_TEAM_ID.
