  2. MINOR version when you add functionality in a backwards-compatible manner or updates to internal (i.e. Lucene, DB) technology (Tier Deployed)
  3. PATCH version when you make backwards-compatible bug fixes. (Tier Deployed)
  4. MAINTENANCE version when you make changes to loaders, admin scripts, etc. (Not tier deployed but public)
  5. BUILD version intended for testing and internal use only.  (Not tier deployed)
