I think there is not much work to do for this specific checklist. Maybe the "Polygon Models" should be checked.
Also the new selection concept (single node selection widgets) are used now instead of the old combo boxes (combo boxes are still mentioned in the checklist).
Edit: New todos for the current release
- Align the content of the checklist with the latest features of the MITK (only release-relevant features / plugins)
- Find appropriate data for the GUI tests and define them in the checklist
- Use the checklist to test the GUI functionality and open tasks for failed test
- Note down GUI tests that can be automated in the future (e.g. put into basic module tests)
