title: Why is session store initializer removed in Rails 5.1.1
body: <p>I went to this <a href="http://railsdiff.org/5.0.0/5.1.1" rel="noreferrer">website</a> to see the differences between Rails 5.0.0 and Rails 5.1.1</p>
  
  <p>Why does 5.1.1 not anymore include: <code>config/initializers/session_store.rb</code>?</p>
