Hello! "Release Early, Release Often" The GiNaC Group is pleased to announce the immediate availability of GiNaC 1.1.5 which contains lots of improvements to the nestedsums functions: - Harmonic polylogarithms now numerically evaluate for arbitrary arguments (parameter must still be positive integers). - The zeta function now can also be given a lst as a parameter in which case it becomes a multiple zeta value. The use of mZeta is deprecated. - The order of parameters for the multiple polylogarithm has been corrected. - Documentation for the nested sums functions zeta, harmonic polylog, multiple polylog, etc. has been added.
