...here is GiNaC 0.6.3. You may download it from the usual ftp-site. We also provide read-only access through anonymous CVS now! You may set up your local copy somehow like this: $ cvs -d :pserver:anoncvs@cvsthep.physik.uni-mainz.de:/home/cvs login enter the password `anoncvs' $ cvs -d :pserver:anoncvs@cvsthep.physik.uni-mainz.de:/home/cvs -z 9 co GiNaC and later keep up-to-date by simply saying 'cvs update' in your GiNaC directory. Here is what's new in version 0.6.3 (0.6.2 only brought changes related to GiNaC-cint): 1 Derivatives are now assembled in a slightly different manner (i.e. they might 'look' different on first sight). Under certain circumstances this can result in a dramatic speedup because it gives hashing a better chance, especially when computing higher derivatives. 2 Some series expansions of built-in functions have been reengineered. 3 The algorithm for computing determinants can be chosen by the user. See ginac/flags.h and ginac/matrix.h. 4 The Dilogarithm (Li2) now has floating point evaluation, derivative and a proper series expansion. 5 Namespace 'std' cleanly disentangled, as demanded by ISO/EIC 14882-1998(E). 6 Some minor bugfixes, one major lsolve()-bugfix and documentation updates. Item 5 should facilitate a transition to GCC3 once the first beta versions become available. The current status of that project is too fragile to give it a real test. Note also, that Cint 5.14.44 (the current release) seems to be rather broken. For those interested in GiNaC-Cint: please use release 5.14.41, i.e. the 'previous' one, to be found on our FTP-server. And no, there were no releases in between, sigh. Sex and drugs and algebra -richy. -- Richard B. Kreckel <kreckel@ginac.de> <http://www.ginac.de/~kreckel/>
