-1.0.6 (<date>)
+1.0.10 (24 July 2002)
+* Powers of indexed objects are now parenthesized correctly in LaTeX output.
+* Input parser handles indices (they have to be specified in the same list
+  as the symbols).
+* Added some limited support for subspaces in the idx and tensor classes.
+* Fixed a bug in canonicalize() (antisymmetric canonicalization of an already
+  sorted list containing two or more equal objects failed to return 0).
+
+1.0.9 (11 June 2002)
+* simplify_indexed() now raises/lowers dummy indices to canonicalize the index
+  variance. This allows some simplifications that weren't possible before,
+  like eps~a.b~c~d*X.a*X~b -> 0 and X.a~a-X~a.a -> 0.
+* Implemented relational::subs().
+* Fixed bug in simplify_ncmul() for clifford objects.
+
+1.0.8 (31 March 2002)
+* Improvements in memory usage of the expand() methods.
+
+1.0.7 (18 March 2002)
+* Fixed LaTeX output of indexed and matrix objects.
+* Fixed matrix::pow(n) for n==0 and added helper functions to create unit
+  matrices "ex unit_matrix(unsigned, unsigned)".
+
+1.0.6 (4 March 2002)
 * "(x+1).subs(x==x-1)" now returns the correct result "x" instead of "x-1".
 
 1.0.5 (27 January 2002)
