A big surprise today is that we have new FAQs for the 40k rulebook and for several armies. Army updates include Chaos Daemons, Dark Eldar, Imperial Knights, Space Wolves, and Tau. Both the Black Legion and Escalation were updated as well.
There seems to be a problem with at least the Dark Eldar Link, and BRB Errata is very minor. Of course I am just getting down to reading through the changes that are available.
