 This file records noteworthy changes.
 
 1.1.0 (<date>)
-* Removed deprecated macros is_ex_a, is_ex_exactly_a and friends.
+* Removed deprecated macros is_ex_a, is_ex_exactly_a and friends for good.
+* Made the hashing more simple and efficient.
+* The scalar_products mechanism allows the specification of an index dimension.
 
 Backlog from 1.0.n:
-* Fixed LaTeX output of indexed and matrix objects.
+* 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).
+* 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.
+* Fixed LaTeX output of indexed and matrix objects and powers thereof.
 * Fixed matrix::pow(n) for n==0.
 * "(x+1).subs(x==x-1)" now returns the correct result "x" instead of "x-1".
 * (l)degree(s), coeff(s, n) and collect(s) were extended to accept expressions
