+* Derivatives are now assembled in a slightly different manner (i.e. they
+  might 'look' different on first sight).  Under certain circumstances this
+  can result in a dramatic speedup because it gives hashing a better chance,
   especially when computing higher derivatives.
-* Many series expansions of built-in functions have been reengineered.
+* Some series expansions of built-in functions have been reengineered.
+* The algorithm for computing determinants can be chosen by the user.  See
+  ginac/flags.h and ginac/matrix.h.
 * The Dilogarithm (Li2) now has floating point evaluation, derivative and a
   proper series expansion.
 * Namespace 'std' cleanly disentangled, as demanded by ISO/EIC 14882-1998(E).
+* Some minor bugfixes, one major lsolve()-bugfix and documentation updates.
 
 0.6.2 (21 June 2000)
