+add_skip_regular_expression_test_property
+-----------------------------------------

+* A new test property, :prop_test:`SKIP_REGULAR_EXPRESSION`, has been added.
+  This property is similar to :prop_test:`FAIL_REGULAR_EXPRESSION` and
+  :prop_test:`PASS_REGULAR_EXPRESSION`, but with the same meaning as
+  :prop_test:`SKIP_RETURN_CODE`. This is useful, for example, in cases where
+  the user has no control over the return code of the test. For example, in
+  Catch2, the return value is the number of assertion failed, therefore it is
+  impossible to use it for :prop_test:`SKIP_RETURN_CODE`.
