+* developer - Changes which impact plugin developers
+* dependencies - Pull requests that update a dependency 
+* internal - Internal only change, not user facing
+* localization - Updates localization files
+* major-bug - Major bug. Will be highlighted on the top of the changelog
+* major-rfe - Major enhancement. Will be highlighted on the top
+* rfe - Minor enhancement
+* regression-fix - Fixes a regression in one of the previous Jenkins releases
+* removed - Removes a feature or a public API
+* skip-changelog - Should not be shown in the changelog
+
+Non-changelog categories:
+* web-ui - Changes in the web UI
+
+Non-changelog categories require a changelog category but should be used if applicable,
+comma separate to provide multiple categories in the label command.
