Go, grab your copy now, as long as supply lasts! Don't let others snatch away the few copies left at <ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/>! Hurry!!! Pronto!! ¡Rapido! Los! The NEWS file says: * In the output and in ginsh, lists are now delimited by { } braces, and matrices are delimited by single [ ] brackets. * simplify_indexed() renames dummy indices so, e.g., "a.i*a.i+a.j*a.j" gets simplified to "2*a.i*a.i" (or "2*a.j*a.j"). * New functions/methods: - canonicalize_clifford() (helpful when comparing expressions containing Dirac matrices) - symmetrize() and antisymmetrize() - numer_denom() (return numerator and denominator in one call) - map() (apply function to subexpressions) - evalm() (evaluate sums, products and integer powers of matrices) * Added a new function match() for performing pattern matching. subs() and has() also accept patterns as arguments. A pattern can be any expression, optionally containing wildcard objects. These are constructed with the call "wild(<unsigned>)" and are denoted as "$0", "$1" etc. in the output and in ginsh. * Positive integer powers of non-commutative expressions (except matrices) are automatically expanded. * Removed cint subdirectory, ginaccint is a separate package now due to packaging considerations. * Several little bugfixes. * More exclamation marks than ever in the announcement.
