 **********
 
 - **Cookie:** The ``CookieInterface::SAMESITE_STRICT``, ``CookieInterface::SAMESITE_LAX``, and ``CookieInterface::SAMESITE_NONE`` constants are now written in ucfirst style to be consistent with usage in the rest of the framework.
+- **Entity:** Fixed a bug in ``Entity::injectRawArray()`` where the default values of ``$attributes`` values disappear. In the case when, after the DB query, the result did not contain all the values for the properties.
