-0.9.1 (<date>)
+1.0.4 (<date>)
+* Faster Bernoulli numbers (Markus Nullmeier).
+* Minor bugfixes and some documentation updates.
+
+1.0.3 (21 December 2001)
+* Fixed a bug where quo() would call vector::reserve() with a negative
+  argument.
+* Fix several bugs in code generation.
+
+1.0.2 (19 December 2001)
+* Input parser recognizes "sqrt()", which is also used in the output.
+* divide(a,b,q) only modifies q if the division succeeds; also, divide(a,b,a)
+  works now.
+* Fixed small bug in dummy index renaming which could cause it to not
+  recognize renamable indices in some cases.
+* power::degree() and power::ldegree() throw an exception when encountering
+  a non-integer exponent.
+* Add output-support for Python bindings.
+
+1.0.1 (22 November 2001)
+* Function sqrfree() handles a few more cases now.
+* Class relational has real canonical ordering now.
+* Handle obscene libreadline version numbers when building ginsh.
+
+1.0.0 (6 November 2001)
+* Some internal reorganization resulting in a general speed-up.
+* The last 3 evaluated expressions in ginsh are now referred to with the
+  tokens '%', '%%' and '%%%'. The old '"', '""' and '"""' remain for
+  compatibility but may be removed in a future version of GiNaC.
+
+0.9.4 (20 September 2001)
+* Functions have better support for external scripting languages.
+* Interface cleanups and bugfixes.
+* Fix silly bug in evalf() that prevented things like 2^Pi being computed.
+
+0.9.3 (16 August 2001)
+* series expansion now much more consistent for small order expansion.
+* lsolve() accepts algorithmic hint as parameter.
+
+0.9.2 (31 July 2001)
+* Epsilon tensor is more functional.
+* simplify_indexed() is better at detecting expressions that vanish for
+  symmetry reasons.
+* Several little bugfixes and consistency enhancements.
+
+0.9.1 (27 June 2001)
+* 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
+  the need for explicit ctors.
 * New functions/methods:
-   - remove_first() and remove_last() for lists
+   - find()
+   - remove_first(), remove_last(), sort() and unique() for lists
    - 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]
+  instead of c.
+* Small bugfixes in pattern matching.
+* Updated libtool to version 1.4.
 
 0.9.0 (7 June 2001)
 * In the output and in ginsh, lists are now delimited by { } braces, and
