The game is crashing, and now down for maintenance already, lets hope that gets fixed quickly (likely so). I've seen a few other minor problems so far, nothing that should be hard to fix. I've only been through Thieves Den, an actual cave with a path that splits a time or two, and did notice that Thugs are now up to level 14 in there, they topped out at 10 in previous observations. There are more than one buildings now so, finding that desk with the arrest warrants in it isnt as easy as it was before... hehe.
Question from prior post about this anticipated update: Unless its changed
I was told (by reliable test source) you lose the "Pirate Master" Notoriety title, and the "Mastered" title on the weapons with this update.
