12.0.0
+- Many bug fixes!
+- Visual Layout Editor:
+ - New RelativeLayout drop support with guideline suggestions for
+ attachments and cycle prevention.
+ - Resize support in most layouts. In LinearLayout, sizes are mapped
+ to weights. Guideline snapping to wrap_content and match_parent.
+ - Previews of drawables and colors in the resource chooser dialogs.
+ - Improved error messages and links for rendering errors, including
+ detection of misspellings of class names.
+- Build system: Delay post compiler phase until actual export or debug
+ to speed up interactive file saves. (This is off by default but can
+ be enabled in the ADT options panel.)
