-1.0.3 (21 December 2001)
+1.1.0 (<date>)
+* 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.
+* Removed dirac_gamma6/7().
+* Added ex::to_polynomial().
+* print_options
+* subs_options
+
+Backlog from 1.0.n:
+* 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
+ of any class (except add/mul/ncmul/numeric) for "s". They should even work
+ if "s" is a "power" object, as long as the exponent is non-integer, but with
+ some limitations. For example, you can "collect(a*2^x+b*2^x, 2^x)" to get
+ "(a+b)*2^x", but "degree(2^(3*x), 2^x)" yields 0 instead of 3).
+* Speedup in expand().
+* Faster Bernoulli numbers (Markus Nullmeier).
* Fixed a bug where quo() would call vector::reserve() with a negative
argument.
-* Fix several bugs in code generation.
+* Several small bugfices in code generation, output and documentation.
1.0.2 (19 December 2001)
* Input parser recognizes "sqrt()", which is also used in the output.
