Today we have 2 security-related launches offered for both customers of our primary 2.2 branch as well as the tradition 2.0 branch. As these launches consist of just safety and security as well as small bugfixes they ought to not create any type of plugin or style compatibility concerns, so you have no great justification not to update.
On our Trac you can see the bugs closed for 2.2.2 as well as 2.0.11 to obtain even more information concerning the troubles taken care of. With a bit much more Trac magic you can see all the changed files for 2.2.2 or 2.0.11.
Many Thanks to Alex C. as well as Benjamin Flesch for assist with this launch.
