 Property Casting
 ----------------
 
 You can specify that properties in your Entity should be converted to common data types with the ``$casts`` property.
 This option should be an array where the key is the name of the class property, and the value is the data type it
 should be cast to. Casting only affects when values are read. No conversions happen that affect the permanent value in
 either the entity or the database. Properties can be cast to any of the following data types:
-**integer**, **float**, **double**, **string**, **boolean**, **object**, **array**, **datetime**, **timestamp**, and **uri**.
+**integer**, **float**, **double**, **string**, **boolean**, **object**, **array**, **datetime**, **timestamp**, **uri** and **int-bool**.
 Add a question mark at the beginning of type to mark property as nullable, i.e., **?string**, **?integer**.
 
 For example, if you had a User entity with an ``is_banned`` property, you can cast it as a boolean:
