将按钮与文本标题 bootstrap 4 beta 对齐

Question

Can someone explain me how to align button with text title using bootstrap 4 beta, I'm sure that this example does not work, because pull-left is changed.

I'm using float-left when I tried to align them, but the button is not exactly where it should be, so title should be on the left and button on right in the same line, here is my JSFIDDLE , so can someone explain me who to achieve this with new bootstrap 4 beta.

<div class="row justify-content-center">
    <div class="col-6">
      <h5><strong>BLOG TITLE GOES HERE</strong></h5>
      <div class="float-right">
        <button type="button" class="btn btn-outline-secondary">Read more</button>
      </div>
      <p class="blockquote-footer text-primary">By Branko Milosevic</p>
