New in version 4.3 (May 2nd, 2011)
- core: u> had wrong stack effect in case of true result.
- core: int-trap triggers an interrupt from software.
- core: /user environment query gives the size of the USER area
- core: sleep takes the sleep mode as parameter.
- ex: added timer-interrupt.frt as an example for using interrupts with forth.
- pub: Erich has presented amforth at the Fosdem 2011 slides and proceedings (published with permission). Thanks Erich!
- core: simplified get/set-order with a changed eeprom content.
- doc: new user guide version from Karl (for version 4.2).
- core: renamed e@/e! to @e/!e to comply with the memory access wordset from forth200x, same with i@/i!.
- core: documentation fixes in many files: reference card.
- core: re-design of the (outer) interpreter using recognizers (dynamically extend the interpeter to deal with new semantics. Defined get/set-recognizer similiar to get/set-order.
New in version 4.2 (September 20th, 2010)
- This release fixes a regression introduced in version 4.1 which may corrupt the flash and EEPROM memory during certain operations.

- It fixes a few bugs and adds some words to the kernel as well.
New in version 3.7 (January 24th, 2010)
- core: atxmega 128 support (no compiler yet).
- core: new word >number. number accepts trailing (!) dots to enter double cell numbers.
- lib: enhanced multitasker with turnkey support. Thanks to Erich Wälde for in depth debugging and testing.
- lib: new word anew drops word definitions if already defined, starts a new generation.
- core: USER area is now split into system and application user areas, system user area is pre-set from EEPROM.
- new: source repository incubator for not-yet-ready-but-interesting projects, volunteers welcome.
New in version 3.6 (October 2nd, 2009)
- 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.
New in version 3.5 (September 2nd, 2009)
- This is mainly a maintenance release.
- It adds a few minor capabilities such as a non-interrupt but small send routine for the serial terminal and a word that looks for the name field for given Forth XT.
New in version 3.4 (April 11th, 2009)
- core: renamed the words for the serial terminal to be more generic since they can deal with any serial port, not only the first one.
- lib: dropped forget since it cannot work with multiple wordlists, fixed marker.
- core: changed again digit? stack effect (and fixed a little bug).
- core: number honors a leading &, $ or % sign to temporarily switch to DECIMAL, HEX or BIN base resp. Thanks to Michael Kalus for factoring the code.

- core: changed digit to digit? found in many other forth's.
- core: new word within.
- core: split application dictionary definition into 2 parts, one for the lower flash, one for the upper (NRWW) flash. Both can be empty, but need to exists.
- core: changed some names for internal constants (baudrate -> BAUD) and registers (EEPE vs EEWE).
