Bug Fixes
- Previously v1.5.1 said DML THEN RETURN is enabled but it did not. Now this feature is ready to use. However, the generated columns in THEN RETURN clause are currently evaluated as null value. The GC support in THEN RETURN is still in progress.
- Restrict emulator's TO_JSON_STRING from handling non-JSON types
New Feature
