title: Docker error: client and server don't have same version
body: <p>Since I just updated Docker to 1.1.0 I get:</p>
  
  <blockquote>
    <p>Error response from daemon: client and server don't have same version (client : 1.13, server: 1.12)</p>
  </blockquote>
  
  <p>Do you know how to fix this?</p>
  
  <p>I switched back to 1.0.1 and everything works again.</p>
