There have been only a small number of breaking changes since the 1.5 SP1 version, as most of the changes this time around have added new functionality.
| • | Refactored Layout code: the layout components now sort and split based on the DICOM hierarchy (study, series and sop) rather than on our presentation model (IImageSet, IDisplaySet, IPresentationImage) in order to provide for display set splitting based on modality-specific concepts. |
| • | Fixed camel casing on members named after UIDs: members like StudyInstanceUID are now spelled StudyInstanceUid. |
