* The undo and redo operations in the builtin PDF viewer can be [[XAML#UBIKPdfViewer|enabled/disabled]].
* Fixed an issue where the parent work package of grouped tasks might display a progress over 100%.
* Fixed an issue where work packages can not be confirmed because the calculated progress is only close to 100% due to the lost of precision.
