- Fixed an issue where recorded logs could become corrupted if MTune was closed without stopping the recording first.
- Fixed a bug that could cause bricked slave-CPUs when updating RACE and PRO ECUs from version before 1.146 to 1.159 or later.
- Fixed an issue in Channel Setup where adding a channel after changing the sorting would reset the list to its previous order.
- Fixed an issue where tables could be partially displayed outside the MTune window.
- Fixed an issue where axis names could appear partially outside the table.
- Fixed an issue where pressing Enter in the Add/Subtract and Adjust % dialogs would unintentionally start editing the selected cell.
