1 This file records noteworthy changes.
4 * Some algorithms in class matrix (notably determinant) were replaced by
5 less brain-dead ones and should now have much better performance.
6 * Checks were completely 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.
11 * Expanded expressions now remember they are expanded to prevent
12 superfluous expansions.
13 * Small bugfixes and improvements in the series expansion.
15 0.5.3 (23 February 2000)
16 * A more flexible scheme for registering functions was implemented,
17 allowing for remembering, too.
20 0.5.2 (16 February 2000)
21 * Mainly fixes a bug in the packaging of release 0.5.1.
23 0.5.1 (14 February 2000)
24 * Fixes a small number of bugs.
26 0.5.0 (7 February 2000)
27 * Expressions can be written ("archived") to files and read therefrom.
28 * Addition of GiNaC-cint, which lets you write complete programs in
29 an interactive shell-like manner in your favoured programming
32 0.4.1 (13 December 1999)
33 * Series Expansion of Gamma function and some other trigonometric
34 functions at their poles works now.
35 * Many more evaluations of special functions at points where
37 * info_flags::rational doesn't return true for complex extensions
38 any more---use info_flags::crational for the old behaviour.
39 info_flags::integer and -::cinteger work similarly, the same
40 holds for types like info_flags::rational_polynomial.
42 0.4.0 (26 November 1999)
43 * First public release.
