+## Backward incompatibility
+
+Due to new [object typehint](https://wiki.php.net/rfc/object-typehint) since PHP 7.2, `Object` is a reserved keyword 
+thus class `OpenStack\ObjectStore\v1\Models\Object` had to be renamed to 
+`OpenStack\ObjectStore\v1\Models\StorageObject`. See [#184](https://github.com/php-opencloud/openstack/pull/184) for 
+details.
