+## Releases
+
+Nominatim follows semantic versioning. Major releases are done for large changes
+that require (or at least strongly recommend) a reimport of the databases.
+Minor releases can usually be applied to existing databases. Patch releases
+contain bug fixes only and are released from a separate branch where the
+relevant changes are cherry-picked from the master branch.
+
