RetroForth is a compact, open source Forth development system. It can be used under FreeBSD, Linux, BeOS, Windows, SCO OpenServer, or as an operating system. It is easy very easy to learn, use, and extend with standard libraries like SDL, and it can also be used to create tight, stand-alone applications.

Changes: This release adds quite a bit of new functionality. Support for aliases, filling memory ranges, and finding addresses of functions has been added. The native version has a serial console, serial port support, parallel port support, hard drive support, and interrupts. There are also two new ports using libc, one of which has support for using shared libraries. A few minor bugs in the conditionals were fixed.
