   In particular an applicator with a single subschema now produces the same best match as the bare subschema would.
   ``relevance`` no longer considers an error's position amongst its siblings.
   When subschemas fail equally deeply, the one which produced fewer errors is now preferred (#1002).
+* Errors produced by a ``false`` subschema now have the correct ``path`` and ``schema_path``, rather than empty ones.
 * Accessing an index with no errors on an ``ErrorTree`` no longer causes that index to appear in the tree (#1328).
   Subtrees also properly propagate lookup errors which were previously missing when accessing indices not in the subtree.
