...which is why the announcement for version 0.7.1 didn't go out. It's to be found on the usual places. It is mainly a bug-fix release, but some of the stuff may represent a heavy improvement. In particular, all those folks who were having this or that particular algebraic problem since 0.7.0, please see if it's been solved. Luck -richy. PS: By the way, this is the second 7 February release... -- Richard Kreckel <Richard.Kreckel@Uni-Mainz.DE> <http://wwwthep.physik.uni-mainz.de/~kreckel/>
