Before the migration, I used to be able to go to a page for each of my projects that would give me a history log of all localization changes. It would list in chronological order, most recent first, all changes made -- phrases created, phrases edited, etc. There doesn't seem to be anything like that now.
This feature will be missed very much whenever I import updates, since I would go there to make sure the import did what I wanted and only what I wanted. (I've caught a few mistakes this way, be they due to the importer not behaving as I expected or due to my own error.)
