-    In PHP 5 there is a new Object Model. PHP's handling of objects has been
-    completely rewritten, allowing for better performance and more features.
+    Starting with PHP 5, the object model was rewritten to allow for better
+    performance and more features. This was a major change from PHP 4.
    </para>
+   <para>
+    Among the new features in PHP 5 are the additions of visibility, abstract
+    and final classes and methods, additional magic methods, interfaces, cloning
+    and typehinting. 
+   </para>
+   <para>
+    PHP 5's object model also significantly changes the way objects are passed,
+    passing a pointer to the object rather than copying the object. Users of
+    PHP 4 are encouraged to test their applications when migrating to PHP 5.
