+you'd like to try it out now. ``ValidatorMixin`` has been removed.

+Practically speaking, this affects validators that subclassed a built-in
+validator and extended a validator function (presumably with an upcall via
+``super``), as the correct way to do so is now to call
+``TheValidator.VALIDATORS["extended_validator_fn"]`` directly in a new
+validator function (and of course to use ``create``). Examples hopefully coming
+soon if more clarification is needed. Patches welcome of course.
 
 It also fixes a number of issues with ref resolution, one for array indices
 (#95) and one for improper handling of unknown URI schemes (#102).
