I was under the impression that the standar procedure for upgrading
was to read the release notes searching for this kind of gotchas. I've
reviewed (again) the release notes for 8.1 and 8.2 and didn't find
anything related but maybe I'm not searching hard enough.

If something is not going a work (or is going a work in a different
way) in some version after loading a shot form a previous one I think
it should be documented or some kind of backwards compatibility
mechanism should be provided.
