Wizards has released the next round of errata. At this rate your books are filled with slips of paper or ink in the margins.
Mostly the Stealth changes from the DDI were put in there and several powers were tweaked, mostly to stop exploits or clarification from the look of it.
DMG has only a couple of changes, one about obscurment that might be useful.
Roughly 20 or so monsters in the MM were revised with one addition in that kobolds are now reptiles. *duh*
