Since GiNaC 0.6.2 silently slipped by...

...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 at cvsthep.physik.uni-mainz.de:/home/cvs login
enter the password `anoncvs'
$ cvs -d :pserver:anoncvs at 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.
