+    <p>With &gnomeversion;, <link href="http://en.wikipedia.org/wiki/OpenGL";>OpenGL</link> support has 
landed in <app>GTK+</app>. This allows OpenGL to draw content in GTK+ applications, using the new 
<code>GtkGLArea</code> widget, and means that heavily 3D-based applications and games can be written in 
conjunction with <app>GTK+</app>.</p>
+
+    <p>OpenGL support in GTK+ &gnomeversion; provides an effective replacement for the previous 
<app>GtkGLArea</app> and <app>GtkGLExt</app> libraries. It is also an important step in the development of 
the GTK+ Scene Graph.</p>

     <p><app>GTK+</app>'s live inspector has had lots of improvements for &gnomeversion;. New features 
include an interactive JavaScript prompt, memory tracking, and a magnifier for inspecting widgets (this is 
particularly useful for theme writers).</p>
     <p>Other improvements include increased isolation of the inspector, so that settings changes only affect 
the application you are inspecting, and a much improved user interface.</p>
