 Dependency Injection Tags
 -------------------------
 
-cmf_request_aware
-~~~~~~~~~~~~~~~~~
-
-.. caution::
-
-    This tag has been deprecated in CoreBundle 1.1 and will be removed
-    in CoreBundle 1.2. Since Symfony 2.3, you can profit from the fact
-    that the request is a `synchronized service`_.
-
-When working with the CMF in Symfony 2.2 and you have services that need the
-request (e.g. for the publishing workflow or current menu item voters), you can
-tag services with ``cmf_request_aware`` to have a kernel listener inject the
-request. Any class used in such a tagged service must have the ``setRequest``
-method or you will get a fatal error::
-
-    use Symfony\Component\HttpFoundation\Request;
-
-    class MyClass
-    {
-        private $request;
-
-        public function setRequest(Request $request)
-        {
-            $this->request = $request;
-        }
-    }
