Use when shipping a Rails engine gem — FIRST run full test suite (bundle exec rspec) and fix ALL failures, verify gemspec metadata and dependencies match tested Rails/Ruby versions, dry-run: gem build *.gemspec && gem push --dry-run *.gem and verify contents, generate CHANGELOG.md organized by category (added/changed/deprecated/removed/fixed), produce step-by-step upgrade notes with before/after code, set semantic version in lib/[engine_name]/version.rb, document deprecations with migration paths, load release assets conditionally and state which one informed the output. Trigger words: version bump, changelog, deprecation, gemspec, upgrade, release, publish gem, ship gem.
