Sorry as usual I can’t make the meeting.

However, I do have one comment about the transition. Is the document [here](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Tutorials/MigrationGuide/Slicer#Slicer_backward_incompatible_changes) expected to serve a list of all major changes? If so I am seeing nothing about the recent coordinate system change for exported models and fiducials.

For me that’s a major change, already impacting our workflow. Perhaps a more comprehensive transition guide is necessary, one not just focused on the developer’s point-of-view, but for user functionality as well…
