Hello, folx! I justed tagged GiNaC 0.6.4 and uploaded it to the usual places. No new functionality was introduced. During the last weeks we ran the complete check-suite thousands of times and were somewhat surprised to find a couple of nasty bugs. Those have been killed and now the check-suite doesn't seem to find any more. Until somebody decides to re-introduce them... Here is the entry from the NEWS file: * Complete revamp of methods in class matrix. Some redundant (and poor) implementations of elimination schemes were thrown out. The code is now highly orthogonal, more flexible and much more efficient. * Some long standing and quite nasty bugs were discovered and fixed in the following functions: add::normal(), heur_gcd(), sr_gcd() and Order_eval() (thanks to Bernard Parisse). Enjoy -richy. -- Richard B. Kreckel <kreckel@ginac.de> <http://www.ginac.de/~kreckel/>
