+1.3.3 (2005-10-24)
+* Fixed bug occuring in algebraic substitutions with expressions involving
+  indices.
+* Fixed bug that selected the wrong algorithm for determinants of purely
+  numeric matrices with at least one floating point element.
+* Fixed bug in function H that caused an infinite recursion for arguments
+  around +-I.
+* Fixed const-correctness in printing handler for GCC 4.0.2.
+* Made lookup in adaptivesimpson precision-aware.
+* Added series expansion for functions (classical) Li and S around x==0.
+* Added fsolve() numerical univariate real-valued function solver.
+* Added functions sub_matrix() and reduced_matrix().
+* Small cleanups. Less warnings with latest GCC.
