title: What does "RTMREL" mean in software versioning?
body: <p>I just installed Visual Studio 2012 and noticed that the version as mentioned in the 'about' menu is:</p>
  
  <p><code>Version 11.0.50727.1 RTMREL</code></p>
  
  <p>I am familiar with <code>RTM</code> (Release To Manufacturing) but am curious what the <code>REL</code> component means.</p>
  
  <p>Anyone have any insight?</p>
