+* Ctors of class numeric are not explicit any more.  All built-in callers for
+  pseudofunctions are now templated and default to ex arguments which relaxes

    - symmetrize_cyclic()
    - decomp_rational()
 * Instead of just totally symmetric or antisymmetric, complex symmetries

   take the trace on both sides, using diff() on a matrix differentiates every
   element etc.
 * diff() works properly with non-commutative products and indexed objects.
+* New option flag "expand_function_args" for expand().
 * Supplement some (now deprecated) macros by inlined template functions:
   - is_of_type(foo, type) -> is_a<type>(foo)
   - is_ex_of_type(foo, type) -> is_a<type>(foo)
   - is_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo)
   - is_ex_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo)
   - ex_to_foobar(baz)  ->  ex_to<foobar>(baz)
-* rem(c, p[x], x) erroneously returned p[x] instead of c.
+* rem(c, p[x], x) (c: numeric, p[x]: polynomial) erroneously returned p[x]

+* Small bugfixes in pattern matching.
+* Updated libtool to version 1.4.
