This release enhances the Arduino hardware support. A lot of internal changes ease the adaption for any atmega type with enough resources. The initial state of the machine control register is saved upon startup. There is one change for better standard conformity that may require code adaption.

This release adds the Arduino Platform and the Atmega2561. Some internal changes give access to the platform information as environment queries. There are documentation enhancements as well.

The application definition files now have full control over what gets included. The word i-store (I!) is turned into a deferred word to enable application specific actions at runtime. It was re-coded in pure assembly to make it easier to integrate it into existing bootloaders. The terminal command prompt is now handled by its own words and can thus easily be changed. The PAD region is no longer used by the system itself. There are a few major bugfixes as well. The core system is smaller in size than in previous versions.

Double cell numbers can be entered directly. The library contains various bugfixes as well. Some internal changes affect the way the memories are structured. Users may need to adapt their applications.

This is both a feature enhancement and a cleanup release. A few new words are added to deal with terminals and (forth-) environment. There are a few internal enhancements to run on big ATmegas and ATXmegas in a future release.
