The release notes for update 7.1 have been posted for the Bullroarer server. This is the public test server. Items in this list are not on the live servers and are subject to change.
The majority of this patch are bug fixes and adjustments to correct things from the known issues list.
Some additional things seen here that are new (at least to me) is the addition of Mystery Cloaks to go along with the Mystery Hauberks. Also all potion vendors have been modified to hold all tiers of potions so you can pick up what you need at any potion vendor.
