 This file records noteworthy changes.
 
-0.6.3 (xx July 2000)
-* Derivatives are now assembled in a slightly different manner (i.e. they 
-  'look' different on first sight).  Under certain circumstances this can 
-  result in a dramatic speedup because it gives hashing a better chance, 
+0.6.4 (10 August 2000)
+* Complete revamp of methods in class matrix.  Some redundant (and poor)
+  implementations of elimination schemes were thrown out.  The code is now
+  highly orthogonal, more flexible and much more efficient.
+* Some long standing and quite nasty bugs were discovered and fixed in the
+  following functions: add::normal(), heur_gcd(), sr_gcd() and Order_eval().

+0.6.3 (25 July 2000)
+* 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)
 * ginaccint.bin is now launched by a binary program instead of by a scripts.
