KB 922815 - Update Rollup 1 for CRM 3.0 released

It looks like about 30 to 40 hot-fixes have been wrapped up into one nice downloadable package. If you have seen "Buffer Overflow detected!" or had trouble with IE 7, you'll want to apply this rollup.

Actually, I'd recommend applying the update even if you haven't seen those common errors.
