This file records noteworthy changes. 0.5.4 (?x?y?z? March 2000) * Algorithms in class matrix (determinant and solve) were replaced by less brain-dead ones and should now have much better performance. * Checks were reorganized and split up into three parts: a) exams (small regression tests with predefined input) b) checks (lenghty coherence checks with random input) c) timings (for coherence and crude benchmarking) * Behaviour of .evalf() was changed: it doesn't .evalf() any exponents. 0.5.3 (23 February 2000) * A more flexible scheme for registering functions was implemented, allowing for remembering, too. * Some Bugfixes. 0.5.2 (16 February 2000) * Mainly fixes a bug in the packaging of release 0.5.1. 0.5.1 (14 February 2000) * Fixes a small number of bugs. 0.5.0 (7 February 2000) * Expressions can be written ("archived") to files and read therefrom. * Addition of GiNaC-cint, which lets you write complete programs in an interactive shell-like manner in your favoured programming language (i.e. C++). 0.4.1 (13 December 1999) * Series Expansion of Gamma function and some other trigonometric functions at their poles works now. * Many more evaluations of special functions at points where exact results exist. * info_flags::rational doesn't return true for complex extensions any more---use info_flags::crational for the old behaviour. info_flags::integer and -::cinteger work similarly, the same holds for types like info_flags::rational_polynomial. 0.4.0 (26 November 1999) * First public release.
