-1.1.5 (4 November 2003)
+1.1.8 (<date>)
+* S(0,p,x) now evaluates numerically.
+
+1.1.7 (11 March 2004)
+* Fixed a bug in canonicalize_clifford().
+* Series expansion now works predictably. All terms with the exponent of the
+ expansion variable smaller than the given order are calculated exactly. If
+ the series is not terminating, the Order function is (at least) of the given
+ order.
+
+1.1.6 (22 January 2004)
+* Added a function option "dummy()" which means "no options". This simplifies
+ the implementation of symbolic functions which are not to be further
+ evaluated.
+* Removed a bug in the numerical evaluation of Li() that caused the system
+ to hang for certain parameter combinations.
+* Fixed a bug in the calculation of hash values for indices that could lead
+ to wrong results or bogus error messages from simplify_indexed().
+* Fixed a bug in the evaluation of harmonic polylogarithms for complex
+ arguments with positive imaginary part.
+
+1.1.5 (5 November 2003)
* Harmonic polylogarithms now numerically evaluate for arbitrary arguments
(parameter must still be positive integers).
* The zeta function now can also be given a lst as a parameter in which case
