+**MINOR** We have added the `unique_case_insensitivity` field for string validation to control whether or not case differences, for example, ABC vs. abc, are treated as conflicting when `unique` is set to `yes`. For more information, see [String Validation](/docs/api/commerce-extensions/custom-fields#string-validation).

       The `float` field_type cannot accurately represent some numbers and so using very small or large numbers might lose precision. We recommend that API clients use either the `integer` field_type if applicable , or the `string` data type if perfect precision or recall is required.
 
       ### String Validation
-      - `min_length`: Specifies the minimum number of characters that can be stored. If set, it must be less than 0 and less than `max_length`.
-      - `max_length`: Specifies the maximum number of characters that can be stored. If set, it must be greater than 0 and `min_length`.
-      - `regex`: [RE2](https://github.com/google/re2/wiki/Syntax) regular expression that used to restrict the specific characters that can be stored. This must be less than 1024 characters.
