The main differences between the 7.x-1.1 release and 7.x-1.0 are:
Changes since 7.x-1.0:
Release incorrectly rolled. Please use 7.x-1.2 instead.
Fixed an issue where plugin titles were not escaped on output.
Functionally equivalent to 7.x-1.0-beta1, which had the wrong major version.
7.x-1.2 is mainly a bug fix release, though a few code clean-ups and other refactorings were committed as well.
