@meme - I found a situation which fails the "upgrade path". For whatever reason (probably because it was top of the list) my collections were configured to use the "author_sort" column. However with the new version this column isn't available. So my collection data isn't migrated.

Is that something you expected to happen/see?

There is something about author_sort mentioned in the debug output - but nothing was ticked/selected on the gui when displayed.

Spoiler:
