title: GitFlow: what is difference between release and master branches?
body: <p>I've just took a look on <a href="http://danielkummer.github.io/git-flow-cheatsheet/" rel="noreferrer">this gitflow cheat sheet</a>. I don't understand the <code>release</code> branch.</p>
  
  <p>Could anybody tell me the difference between <code>release</code> and <code>master</code> branches?</p>
