A version 2.7.highest list it in modules as disabled. One can hide/unhide it, but it doesn't show in the pick list of activities to choose from when creating content (if it does show elsewhere it shows '(disabled)' after listing.
Also noticed the Assignment Upgrade Helper link in the Site Admin menu is there still.
And a question concerning restores ... IF one were to attempt to restore a course from an earlier version of Moodle (a 2.4, 2.5, 2.6, etc) will the restore fail? or will Moodle auto convert those assignments?
Is this mentioned in release notes somewhere?
