🔥 API-breaking changes

Default label group names

Default label group names now start at 1 like "Group 1" instead of "Group 0".

BooleanOperation

The BooleanOperation class was refactored into a namespace with free functions. See the Segmentation Utilities view code for examples on how to migrate.

MaskImageFilter

The min/max value features were removed from the MaskImageFilter, since they are not supported by ITK's MaskImageFilter and were not really used in our code base. As an alternative you may use the statistic filter to compute min/max values.

Removed classes

The following legacy classes were not used anymore in the MITK code base and hence were removed:

• QmitkContourModelToImageWidget
• QmitkDataSelectionWidget
• QmitkExternalProgramsPreferencePage
• QmitkGnuplotWidget
• QmitkSurfaceToImageWidget
• FeatureBasedEdgeDetectionFilter
• HotspotMaskGenerator
• PointCloudScoringFilter
