Kisil). +* Symbolic integration class added (C. Dams). +* The multiple polylogarithm Li now evaluates numerically for arbitrary arguments. +* New function G added (another notation for a multiple polylogarithm). + +1.2.4 (12 October 2004) +* Added ex::unitcontprim() to compute the unit, content, and primitive parts + of a polynomial in one go. +* binomial(n, k) evaluates for non-integer arguments n. +* Li(2,x) now evaluates for +-I. +* Optimized Li(2,x). +* Fixed bug in Li(n,x) (if Li(2,x) was calculated with high precision the + enlargement of the look-up table caused a segmentation fault). +* Fixed another bug in the series expansion of powers, and a bug in + power::info(). + +1.2.3 (13 August 2004) +* Added variants of dirac_trace() and color_trace() that take the trace over + more than one representation label by specifying a set or list of labels. +* diracgamma::contract_with() uses Chisholm identities in 4 dimensions to + produce more compact results. +* Fixed a bug in the series expansion of powers. +* The --enable-html-doc and --enable-ps-doc configure options are gone. + Documentation in HTML, DVI, PostScript, and PDF formats is now built with + "make html", "make dvi", "make ps", and "make pdf", respectively. The only + documentation that gets built by default are the tutorial in .info format + and the manpages. + +1.2.2 (3 August 2004) +* Added const_preorder_iterator and const_postorder_iterator classes (and + associated methods ex::pre/postorder_begin/end()) providing tree traversal + with iterators. +* Fixed the LaTeX output of the varidx class. +* Fixed bugs in series expansion and complex conjugation. +* (p.i*p.i).get_free_indices() returns the correct result () instead of (.i). +* Symbolic functions without any eval(), evalf() etc. functions now work + properly. +* integer_content(), content(), and primpart() now also work for polynomials + with rational coefficients (calculating the LCM of coefficients' + denominators). +* Added method matrix::rank(). +* Added function resultant(). +* Added integer_content() function to ginsh. 1.2.1 (23 April 2004) * Fixed infinite recursion in atan2_evalf() and improved atan2_eval(). -- 2.44.0
