3 0.5.4 (?x?y?z? March 2000)
4 * Algorithms in class matrix (determinant and solve) were replaced by
5 less brain-dead ones and should now have much better performance.
6 * Checks were reorganized and split up into three parts:
7 a) exams (small regression tests with predefined input)
8 b) checks (lenghty coherence checks with random input)
9 c) timings (for coherence and crude benchmarking)
10 * Behaviour of .evalf() was changed: it doesn't .evalf() any exponents.
12 0.5.3 (23 February 2000)
13 * A more flexible scheme for registering functions was implemented,
14 allowing for remembering, too.
17 0.5.2 (16 February 2000)
18 * Mainly fixes a bug in the packaging of release 0.5.1.
20 0.5.1 (14 February 2000)
21 * Fixes a small number of bugs.
23 0.5.0 (7 February 2000)
24 * Expressions can be written ("archived") to files and read therefrom.
25 * Addition of GiNaC-cint, which lets you write complete programs in
26 an interactive shell-like manner in your favoured programming
29 0.4.1 (13 December 1999)
30 * Series Expansion of Gamma function and some other trigonometric
31 functions at their poles works now.
32 * Many more evaluations of special functions at points where
34 * info_flags::rational doesn't return true for complex extensions
35 any more---use info_flags::crational for the old behaviour.
36 info_flags::integer and -::cinteger work similarly, the same
37 holds for types like info_flags::rational_polynomial.
39 0.4.0 (26 November 1999)
40 * First public release.
