+New Stuff:

+Non-Backwards Compatible Changes:
+   - Renamed the support_vectors member of the decision_function and
+     distance_function classes to basis_vectors.  This name more appropriately

+   - Changed the matrix_exp interface slightly.  This could only impact users

+     compiler error then you don't have to worry about it.
