title: Why is Ruby 1.8.6 RC1 more recent than Ruby 1.8.6 Final?

  <p>and then </p>

    <p><a href="http://rubyinstaller.org/download.html" rel="nofollow noreferrer">http://rubyinstaller.org/download.html</a></p>
  </blockquote>
  
  <p>however over there, it seems that</p>
  
  <blockquote>
    <p>Ruby 1.8.6 RC1 (patchlevel 383)</p>
  </blockquote>
  
  <p>is actually more recent than </p>
  
  <blockquote>
    <p>Ruby 1.8.6 RC2 (patchlevel 27)</p>
  </blockquote>
  
  <p>or</p>
  
  <blockquote>
    <p>Ruby 1.8.6 Final (patchlevel 26)</p>
  </blockquote>
  
  <p>If I install them on different machines, the RC1 actually shows a more recent date than RC2 or Final, by using </p>
  
  <pre><code>ruby -v
  </code></pre>
  
  <p>What's the rule?  Does it go strictly by patchlevel?  That is, the patchlevel decides how update it is, instead of whether it is RC1, RC2, or Final?</p>
