+TBA to NEWS for this branch.

+* Forward incompatible changes
+
+Applying these changes will make your program work with this version of
+Guile and continue working with older versions.
+
+** vector->list and vector-copy require a true vector argument.
+
+Use array->list and array-copy (from (ice-9 arrays)) on general arrays.
+
+** scm_vector_elements / scm_vector_writable_elements require a true vector 
argument.
+
+Use scm_array_get_handle and scm_array_handle_elements /
+scm_array_handle_writable_elements on general arrays.
+
+* Backward incompatible changes
+
+Applying these changes will make your program work with this version of
+Guile and STOP working with older versions.
+
+** scm_array_p takes a single argument.
+
+This function used to take a second unused argument for the sake of
+compatibility with older versions of Guile. Just remove this argument from your
+calls.
