Played yesterday, and there were plenty of changes. They changed the skill points use, in that you have to buy 5 skills from the first tier then 5 from the 2nd tier, then you can unlock the last tier of slotable skills.
Also noted 1 skill challenge NPC that was not working, (bug reported) and 1 item that had poor grammar in the description (reported)
The Mini map has changed it is no longer a compass, its now a window that is sizable (sill no red dots that I saw).
The UI had some changes, the dodge bar is now over the health ball. And the area where the dodge bar was before now has conditions and boons shown there.
Some other things I saw in game were the fact that the game speed is up a bunch I was able to turn the graphics way up with still no noticeable lag.
The game played really well except when I was crafting and hanging out at the bank in DR when I noticed a small bit of lag.
They added a tutorial hints that pop up on screen. These are very good if you don't already know what the hint said, and you can turn it off too.
Overall its noticeable they did change some things, based on feedback, and this continues to be even in beta a solid game, I am still very impressed with it.
