1 This file records noteworthy changes.
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 tests with predefined input)
8 b) checks (lenghty consistency checks)
9 c) timings (for crude benchmarking)
11 0.5.3 (23 February 2000)
12 * A more flexible scheme for registering functions was implemented,
13 allowing for remembering, too.
16 0.5.2 (16 February 2000)
17 * Mainly fixes a bug in the packaging of release 0.5.1.
19 0.5.1 (14 February 2000)
20 * Fixes a small number of bugs.
22 0.5.0 (7 February 2000)
23 * Expressions can be written ("archived") to files and read therefrom.
24 * Addition of GiNaC-cint, which lets you write complete programs in
25 an interactive shell-like manner in your favoured programming
28 0.4.1 (13 December 1999)
29 * Series Expansion of Gamma function and some other trigonometric
30 functions at their poles works now.
31 * Many more evaluations of special functions at points where
33 * info_flags::rational doesn't return true for complex extensions
34 any more---use info_flags::crational for the old behaviour.
35 info_flags::integer and -::cinteger work similarly, the same
36 holds for types like info_flags::rational_polynomial.
38 0.4.0 (26 November 1999)
39 * First public release.
