-0.5.4 (?? 2000)
-* Algorithms in class matrix (determinant and solve) were replaced by
+0.6.0 (...)
+* IMPORTANT: Several interface changes make programs written with GiNaC
+ much clearer but break compatibility with older versions:
+ - f(x).series(x,p[,o]) -> f(x).series(x==p,o)
+ - series(f(x),x,p[,o]) -> series(f(x),x==p,o)
+ - gamma() -> Gamma()
+ - EulerGamma -> gamma
+ - beta() -> Beta()

+0.5.4 (15 March 2000)
+* Some algorithms in class matrix (notably determinant) 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 tests with predefined input)
- b) checks (lenghty consistency checks)
- c) timings (for crude benchmarking)
+* Checks were completely 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.
+* Expanded expressions now remember they are expanded to prevent
+ superfluous expansions.
+* Small bugfixes and improvements in the series expansion.
0.5.3 (23 February 2000)
* A more flexible scheme for registering functions was implemented,
