-            The `:tokenizer` option is deprecated, and will be removed in Rails 5.1.
-            You can achieve the same functionality by defining an instance method
-            with the value that you want to validate the length of. For example,
-
-                validates_length_of :essay, minimum: 100,
-                  tokenizer: ->(str) { str.scan(/\w+/) }
-
-            should be written as
-
