+This is a list of hashes, each hash representing a change to the bug. Each 
+hash has the following members: C<field_name>, C<bug_when>, C<old>, C<new>

+C<attach_id> or C<comment_id>; if either is present, there will be 
+C<isprivate>. See C<_get_diffs> in F<Bugzilla/BugMail.pm> to see exactly how 
+it is populated. Warning: the format and existence of the "diffs" parameter 
+is subject to change in future releases of Bugzilla.
