The patch notes for the new Empyrean Age 1.1 patch are now LIVE. There’s a sickeningly huge amount of tweaks, fixes, and changes here. I don’t even know where to start in posting an analysis of it yet, so have a read.
Update: Sounds like other than a ridiculous amount of bug fixes, one of the biggest additions to this is the CONCORD and security changes talked about in a recent dev blog. Details for those changes have been added to the patch notes.
