MathPiper was the main CAS for GeoGebra up until around this past February. MathPiper has good potential to be a solid entry-level CAS, but in February I determined that it needed another year or so of development to be suitable for use by GeoGebra and GeoGebra 4.0 was scheduled to be shipped this August. Around that time I found an unadvertised Java version of Reduce sitting in the Reduce repository (called Jlisp) and with the help of the lead Reduce developer (Arthur Norman) I created a modified version of Jlisp that would work with GeoGebra. This modified version of Jlisp is called MPReduce for now. Sometime in late Spring the GeoGebra developers asked if it was possible to create a JavaScript version of MPReduce for use with the JavaScript version of GeoGebra they were working on so I ported MPReduce to JavaScript for them. Anyway, now that MPReduce is almost finished being integrated with GeoGebra, I have turned my efforts back to working on MathPiper because I think it is still better suited to be an entry level CAS than most commercial-quality CASs are.
