 ### Updated
 - Log timestamps now explicitly display timezone.
 - **[Breaking Change]** `PreparedStatement.setTimestamp(int, Timestamp, Calendar)` now properly applies Calendar timezone conversion using LocalDateTime pattern (inline with `getTimestamp`). Previously Calendar parameter was ineffective.
+- `DatabaseMetaData.getColumns()` with null catalog parameter now retrieves columns from all available catalogs when using SQL Execution API.
 
 ### Fixed
 - Fix timeout exception handling to throw `SQLTimeoutException` instead of `DatabricksSQLException` when queries timeout.
