New in this release:
- Improved zoom and pan for Simulink viewer / differ.
  
- Mouse-wheel to zoom
 - Middle-mouse-drag to pan
 
 - No more KeyRing auto-login.
  
- The KeyRing no longer prompts for your password on every login. It now waits until it needs your password for something.
 
 - The license manager has been improved to make changing versions easier.
 - Optional auto-close for deleted files.
 - Darkened some UI colors to improve readability on bright monitors.
 - Added menu items for 
File -> Open fileandFile -> Diff files.- These don’t take advantage of DiffPlug’s full capability, but they make it easier for new users to get comfortable with DiffPlug.
 
 
Bugs fixed in this release:
- Fixed error when right-clicking on the DiffList with no files selected.
 - Fixed a bug which was causing the Simulink parser to erroneously warn on models with non-standard port dimensions.
