Contrary to what you say, the "New in Launchpad" should also be in the translate form.
For package maintainer there should be an easy indicator on the "template overview page" telling whether a language changed (new, changed strings) or not. The colored bar is nice but works only for large numbers. I would suggest to add a small mark behind that colored bar (e.g. a star). This is used in many text editors to mark changes in window title and should be easy understandable (when documenting it on mouseover).
