title: List of OpenGL functionality removed from the core profile
body: <p>Is there any comprehensive list on OpenGL 3.3 above, where I can find what functions are deprecated / not available anymore?</p>
  
  <p>Say, <code>glLoadIdentity()</code> I don't know if it is removed or not. </p>
  
  <p>I looked into the <a href="http://www.opengl.org/sdk/docs/man4/" rel="nofollow noreferrer">OpenGL 4.1 Reference Page</a> and didn't find it there. Can I safely assume that its a removed function? Is this a way to know it the function exists anymore?</p>
  
  <p>In the reference page it says that, "These man pages only document the core context." What does it mean by that? What are the things that are absent from that reference page?</p>
  
  <p>What is compatibility profile? Is there any comprehensive list of features available on a particular version of OpenGL?</p>
