Breadcrumb migration

Bootstrap 3 breadcrumb:

Separators are automatically added in CSS through :before and content.

<ol class="breadcrumb">
  <li><a href="#">Home</a></li>
  <li><a href="#">Library</a></li>
  <li class="active">Data</li>
</ol>

Bootstrap 2 breadcrumb:

<ul class="breadcrumb">
  <li><a href="#">Home</a> <span class="divider">/</span></li>
  <li><a href="#">Library</a> <span class="divider">/</span></li>
  <li class="active">Data</li>
</ul>

The difference is item-list type and divider
