title: How do I run a specific release of Meteor?
body: <p>I've updated to 0.6.0 but would like to run my project in 0.5.8. So when I run:</p>
  
  <blockquote>
    <p>meteor --release 0.5.8</p>
  </blockquote>
  
  <p>it returns</p>
  
  <blockquote>
    <p>0.5.8: unknown release.</p>
  </blockquote>
  
  <p>What is the correct format for targeting a specific release?</p>
