title: How to update SBT version using homebrew?
body: <p>I installed SBT v0.12.4. Now I want to update it to v0.13.x, so I have used the command </p>
  
  <pre><code>brew install sbt
  </code></pre>
  
  <p>It says that it has correctly installed SBT 0.13.x. but if I ask on terminal the version of SBT, it says 0.12.4. How to update it?</p>
