· There are now some rudimentary compiler safety checks.
· Some minor bugs are fixed as well.
March 27th, 2012· This version adds the last missing word from the Forth Standard CORE Wordset: EVALUATE.
· Some debugger tasks like a call tracer and a profiler are available now.
· Optional support for unified memory addresses is added.
· Internal changes open the road to more features like LOCALs.
· A few bugs are fixed.
February 5th, 2012· This version allows REFILL and SOURCE to be changed at runtime.
· The multitasker can now be used in turnkey applications.
· There are some new words from the strings standard word set.
· The documentation is improved, and some new utilities, including a call tracer, are added.
October 7th, 2011· This version adds or changes a few words useful for microcontroller programming.
May 25th, 2011· This version stabilizes the changes introduced in the previous 4.3 release.
· Amforth now fully supports interrupts in forth high level language.
· The system can be customized to ignore case when doing dictionary lookups.
· The documentation is expanded and many new examples are added.
· Some new words from the forth200x standard are added, and code cleanups are applied as well.
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.
September 20th, 2010· This release fixes a regression introduced in version 4.1 which may corrupt the flash and EEPROM memory during certain operations.
· New words which are currently being defined are now invisible for dictionary lookups until the definition is finished.
· A IEEE754 single precision floating point library is now available.
September 3rd, 2010· This version adds the necessary files to work with most of the current atmega controller types.
· It fixes a few bugs and adds some words to the kernel as well.
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.
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.
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.
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.
February 22nd, 2009· Besides some minor bugfixes and better error handling, this release adds the ANS94 Search Order Extension Wordlist.
January 10th, 2009· core: bugfix for trailling 0x00 byte during itype.
· core: enable use of other usart port than 0.
· pc-host: Ken Staton wrote a nice pc based terminal with upload functionality.
· core: New controllers: ATmega328P and ATmega640.
· 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).
· core: new directory drivers for low level driver functions. Currently only the generic ISR and the USART0 interrupt handler.
November 11th, 2008· This release changes the storage structure of the dictionary, and simplifies many words operating on it.
· It adds only a few new words, such as environment, however.
October 18th, 2008· This release adds experimental code for the A/B forth VM registers as discussed at EuroForth 2008.
· The pictured numeric output was completely rewritten and conforms to the ANS94 standard, and some internal cleanups should ease the deployment on systems with external RAM.
· A few bugs are fixed.
