Well, I haven't really had a chance to check out the update. I've been grinding away. However, I did notice changes to the world map - clan maps are darkened, what looks like new map grids (working?), and otherwise bold type map coordinates (purpose?). All good changes so far!
I did stumble across a new house in Ashdown, went inside, but NPC refused to talk to me

Not sure if there's a level requirement (I'm 429) or not. My only other comment is that it would be nice if there was a post which stated the changes (if even "high" level info). But, I've read that this is only the first of several updates...
