-0.4.0 (26 November 1999)
-* First public release.
+0.6.0 (...)
+* Important interface changes:
+  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,
+  allowing for remembering, too.
+* Some Bugfixes.

+0.5.0 (7 February 2000)
+* Expressions can be written ("archived") to files and read therefrom.
+* Addition of GiNaC-cint, which lets you write complete programs in
+  an interactive shell-like manner in your favoured programming
+  language (i.e. C++).
