Those who are not happy with AmForth turning GPLv3 may switch to
AmForth-Shadow https://github.com/wexi/amforth-shadow that is, and
will continue to be, GPLv2. GPLv2 is the license that Linux kernel
carries and, likewise, (in a careful manner) can be deployed in
commercial products of replica watches without forcing underived code to fall under a GPL
license too. ...

AmForth-Shadow was born as a result of AmForth rejection of a series of
patches whose author felt had a significant merit (and bound by GPLv2
had to be disclosed). One example, the concept of soft interrupts
(Second Level Interrupt Handlers, SLIH) which makes it easier to write
real-time code. These soft interrupts complement a revised
implementation of AmForth cooperative multi-tasking library
(lib/tasks.frt).

It is the commitment of AmForth-Shadow developer to release further
original code to AmForth-Shadow and there will be no merging of code or
documentation from AmForth further to
svn://svn.code.sf.net/p/amforth/code/trunk@1687 which announced its
change of license.

Let me end this message with the hope that the advantages of competition
in the AmForth* arena will outweigh its downside.

Thanks, Enoch.

P/S Software licensing is a sensitive topic that is well known to ignite
senseless Internet flames. Such communications I intend to ignore.
