 - Added support for `copy_grants` parameter when registering UDxF and stored procedures.
 
-#### New Features

 #### Improvements
+
 - Disables sql simplification when sort is performed after limit. 
   - Previously, `df.sort().limit()` and `df.limit().sort()` generates the same query with sort in front of limit. Now, `df.limit().sort()` will generate query that reads `df.limit().sort()`.
   - Improve performance of generated query for `df.limit().sort()`, because limit stops table scanning as soon as the number of records is satisfied.
 
+#### Bug Fixes
+
+- Fixed a bug where the automatic cleanup of temporary tables could interfere with the results of async query execution.

 ### Snowpark pandas API Updates
