This update has some new features that make a variety of things in Axure RP easier to do like image slicing, importing from file to file, and duplicating masters, as well as a number of bug fixes.
Feature highlights:
Image slicing (right click image, Edit Image->Slice Image)
Option to import styles and variables used in a custom widget when that widget is added to a page
Import manager supports importing multiple types (pages, masters, styles) at one time
Removed the variable limit (however we still recommend using 25 or less if viewing prototypes in IE)
Undo check out for shared projects
Converting widgets to a dynamic panel or master (right click widgets, Convert)
Duplicate masters
Duplicating a page or master opens the copy for editing
Shortcut to toggle grid visibility (Ctrl+Alt+D)
FIPS compliance (mostly for government computers)
