- Card Utility now supports DVP EX2-64K series: Added the EX2-64K series under the controller type “DVP”.

- Added bit access functionality for array type symbols (e.g., arrayVar[index].0) in AH series.
- Fixed the issue where the download window failed to close automatically when the “initial value” option was checked during download, even though the Delta DVP series program did not use initial values.
