We tried to make an update to our TaskZilla, so that recent fixes and some improvements find their way to our users. I knew that it would be no easy task, because we made many internal changes, but I didn't expect the Bugzilla-team to be that productive.
Well, after a few hours, we gave up and decided to break the update and go back to our backup copy. Since our internal changes, especially the layout-change, aren't finished yet, the update will be done after that stuff has finished. It will be more work then, but it doesn't interfere with internal development then, and we have more time to finish the update.
