I wish. The truth is that Kale releases on random Sundays when he has free time. Devs get about a 12 hour advance warning, and for devs in the US a large chunk of that time is when we're normally asleep due to how the time zones line up. It wasn't a rush, it was just a snapshot of SVN at an inopportune time. Since the "old" CHDs all continue to work flawlessly (and in fact you'll have less hassle with u1 if you *don't* update your CHDs) there's no reason to panic.
