GiNaC 1.8.7 released
by Richard B. Kreckel 12 Aug '23

12 Aug '23

Hi, GiNaC 1.8.7 has been released. Here're the news: * Fix series expansion of polynomial(x)^n for small and large n. Previously, this could return two Order terms or an Order term even though the series was terminating at a lower order. * Fix bugs in internal parser from strings. The operator precedence of the internal parser was inconsistent and has now been harmonized with that of ginsh. * Make ginsh evaluate line-by-line in non-interactive mode. This helps programs invoking ginsh as a sub-program. * Several build fixes. Happy hacking! -richy. -- Richard B. Kreckel <https://in.terlu.de/~kreckel/>

Before calling pseries::power_const(), make sure the basis series has sufficient terms. In particular, do not shrink the order of expansion - only grow it. Fix various hairy problems in pseries::power_const() when a polynomial is raised to a positive integer power. (The special cases here can actually also be computed by Taylor expansion but the fixes should be more general.) Also add test cases.
