 - Entity. Timestamp casting now throws an exception when an invalid value is passed
 - ``Entity::castAsJson`` uses external cast handler ``JsonCast::get``.
 - ``Entity::mutateDate`` uses external cast handler ``DatetimeCast::get``.
+- In order for ``Config\**`` classes to get their respective properties' values from the ``.env``, it is now necessary to namespace the property with the name of the class. Previously, the property names are enough but now disallowed because it can get system environment variables, like ``PATH``.
