Just downloaded the BnF update patch whatever. Read the revised blocking and am not 100% on it.
I think what is getting me hung up is that essentially you're pre-blocking as you make blocking attack rolls before the attack. So you also decide if you're going to block a full-rounds actions or not. But if you're not going first, do you then get to block when someone attacks, assuming your not flat-footed? I'm guessing you can, but maybe I'm just up too late or whatever and it isn't meshing as well as I'd hoped in my mind right now.
As for errata; two things I noticed was that Contemplative Master still has a requirement of Mediation 3 ranks, which is now rolled into Concentration. Counterstrike, Improved is listed twice, once as what I just wrote and once as Improved Counterstrike. Finally, not sure if it is errata or not, but I just don't get why you'd get something like Hook, when you can get Heart Punch. They both add a die to damage, and with heart punch if you are feeling vicious you can possibly stun someone.

edit: block, improved and improved block are another double posting, although one is stated out like the previous one about not getting hurt if you block it well enough.
