Please go ahead and update to 1.11 (with the 1153 hotfix). This should involve simply using the updater in the game menu. As always, you should clear out your override directory first. I will be updating the server tonight.
There are some reported issues, but looking around it seems that most persistent worlds are using it. One issue that some have reported is that sometimes the game will slow down after an area transition. If this happens, you can hit "C" to bring up your character page, and then close it. This gets things back to normal.
