I rechecked all the breaking changes to ReferenceList, Item and Property again and uploaded an additional pull request.
- https://github.com/wmde/WikibaseDataModel/pull/616 (merged) should be merged first because it fixes a critical bug. Note that this is currently not in the release notes. I would like to update the release notes manually before doing an actual release, to not run into more merge conflicts.
- https://github.com/wmde/WikibaseDataModel/issues/623 (merged) and
- https://github.com/wmde/WikibaseDataModel/pull/621 are my new pull requests. I will rebase the 2nd when the 1st is merged.
- I also rebased https://github.com/wmde/WikibaseDataModel/pull/603. It contains a series of fixes I uploaded a week ago. Still nobody reviewed the changes, all posts in the discussion are about something else.
- https://github.com/wmde/WikibaseDataModel/pull/622 makes a regression test more obvious.
