+# What's New in Data API builder 0.6.14
+
+This is the patch for March 2023 release for Data API builder for Azure Databases
+
+## Bug Fixes
+- Address query filter access deny issue for Cosmos in #1436.
+- Cosmos DB currently doesn't support field level authorization, to avoid the situation when the users accidentally pass in the ```field``` permissions in the runtime config, we added a validation check in #1449
