+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 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.
+* A more flexible scheme for registering functions was implemented,
+  allowing for remembering, too.
 * Some Bugfixes.
