* Changes to Scheme functions and syntax
+** New function hashx-remove!
+
+This function completes the set of 'hashx' functions.
+
** The concept of dynamic roots has been factored into continuation
barriers and dynamic states.
* Changes to the C interface
+** The functions scm_hash_fn_remove_x and scm_hashx_remove_x no longer
+ take a 'delete' function argument.
+
+This argument makes no sense since the delete function is used to
+remove a pair from an alist, and this must not be configurable.
+
+This is an incompatible change.
+
** A new family of functions for converting between C values and
Scheme values has been added.
