+# The first three numbers refer to the last released version.
+#
+# The database patch level tracks important changes between releases
+# and must always be increased when there is a change to the database or code
+# that requires a migration.
+#
+# When adding a migration on the development branch, raise the patch level
+# to 99 to make sure that the migration is applied when updating from a
+# patch release to the next minor version. Patch releases usually shouldn't
+# have migrations in them. When they are needed, then make sure that the
+# migration can be reapplied and set the migration version to the appropriate
+# patch level when cherry-picking the commit with the migration.
+#
+# Released versions always have a database patch level of 0.
