+LilyPond no longer automatically infers a @samp{\defaultchild}
+context in a context definition with @samp{\accepts} clauses.  Any
+context definition without an explicit or inherited
+@samp{\defaultchild} definition counts as a @samp{Bottom} context
+and will be eligible for rhythmic events and overrides without
+causing the implicit creation of other contexts.  Be sure to
+specify a @samp{\defaultchild} for non-@samp{Bottom} contexts when
+defining them from scratch.
