  • Correct LabelShapeStatistics baseline for OrientedBoundingBoxVertices results. ( See ITK commit 50c695 for details. )
  • Fix potential double memory free of pixel container in results from internal image to vector image conversions.
  • Fix RelabelComponentImageFilter incorrect object size computation with sorting enabled. ( See ITK commit 162101 for details. )
  • Fix potential ITK pipeline execution error when a filter execute on a vector image by per component.
  • Add C++11 move semantics support to the Image class.
  • Add direct support for C++11 lambda command to the ProcessObject class.
  • Add GetBufferAsVoid method to the Image class.
