-	 * Creates a new object instance.
-	 *
-	 * This method calls [[\Yii::create]] to create the new object instance.
-	 *
-	 * This method differs from the PHP `new` operator in that it does the following
-	 * steps to create a new object instance:
-	 *
-	 * - Call class constructor (same as the `new` operator);
-	 * - Initialize the object properties using the name-value pairs given as the
-	 *   last parameter to this method;
-	 * - Call [[Initable::init|init]] if the class implements [[Initable]].
+	 * Creates a new instance of the calling class.
 	 *
 	 * Parameters passed to this method will be used as the parameters to the object
 	 * constructor.
 	 *
-	 * Additionally, one can pass in an associative array as the last parameter to
-	 * this method. This method will treat the array as name-value pairs that initialize
-	 * the corresponding object properties. For example,
+	 * This method does the following steps to create a object:
+	 *
+	 * - create the object using the PHP `new` operator;
+	 * - if [[Yii::objectConfig]] contains the configuration for the object class,
+	 *   initialize the object properties with that configuration;
+	 * - if the number of the given parameters is more than the number of the parameters
+	 *   listed in the object constructor and the last given parameter is an array,
+	 *   initialize the object properties using that array;
+	 * - call the `init` method of the object if it implements the [[yii\base\Initable]] interface.
+	 *
+	 * For example,
 	 *
 	 * ~~~
-	 * class Foo extends \yii\base\Object
+	 * class Foo extends \yii\base\Object implements \yii\base\Initable
 	 * {
 	 *	 public $c;

 	 *		 ...
 	 *	 }
+	 *	 public function init()
+	 *	 {
+	 *		 ...
+	 *	 }
 	 * }
 	 *
-	 * $model = Foo::create(1, 2, array('c' => 3));
+	 * $model = Foo::newInstance(1, 2, array('c' => 3));
 	 * // which is equivalent to the following lines:
 	 * $model = new Foo(1, 2);
 	 * $model->c = 3;
+	 * $model->init();
