New features
Multi-file compilation
It is now possible to use the IAR Embedded Workbench IDE to define compilation units with multiple files that will be compiled together, resulting in more efficient code size optimization.
visualSTATE build integration
visualSTATE design projects can now be included in an IAR Embedded Workbench project. This enables the code generation facility of visualSTATE to be run automatically when needed as part of the normal IAR Embedded Workbench build chain.
TheOptimizations tab in the Options menu has been redesigned to make it easier to target your application for size or speed optimization.

В общем почти только косметические изменения.
