There have been quite a lot of changes for the 1.5 version, but most notable are those mentioned in the Preface:
| • | New Interactive Graphics: the new design of our "Interactive Graphics" is far more robust and flexible than it was previously. Now, instead of writing your graphics, it's far more likely that you'll be able to simply build your graphics from reusable components. |
| • | Refactored Sop classes: the Sop and ImageSop classes are now just simple bridges to a lower level construct: the ISopDataSource, which itself is really just an abstraction of a DICOM file. |
