-* gcd now allows the user to override (some of the) heuristics.
-* Replaced custum RTTI by standard C++ RTTI.
-* Definition of archiving methods now optional when declaring a new GiNaC class.
+* New, faster (recursive descent) expression parser.
+* Faster GCD computation.
+* gcd() now allows the user to override (some of the) heuristics.
+* Writing extensions classes is simpler now:
+  - Replaced custom RTTI by standard C++ RTTI.
+  - Definition of archiving methods now optional when declaring a new GiNaC class.
 * Fixed recursion in polynomial divide that caused a significant slowdown in
   sqrfree().
 * Improved lsolve() of systems containing non-numeric coefficients.
