Hi, A new GiNaC release is out and available. These are the changes: * Fix pow(+(...),2).expand() where the sum contained roots of expressions. * Speed-up pow(+(...),n).expand() where n > 3. * Fix a crash in PolyLogs of rational numbers. Happy hacking -richy. -- Richard B. Kreckel <http://in.terlu.de/~kreckel/>
