+        MongoDB support is deprecated in v7 and will be removed in future versions. Important details:

+        1. New features may not be available with MongoDB
+        2. Testing coverage for MongoDB will be limited

+        Migrate to CockroachDB before upgrading to v7. See migration instructions at:
