AdminLTEOptions not working in v2.4?

I’m using version 2.4 for setting up a simple admin panel for a client and I just wanted to customize the default collapse/expand icons, so here’s my setup:

<script>
var AdminLTEOptions = {
  boxWidgetOptions: {
    boxWidgetIcons: {
      collapse: 'fa-chevron-up',
      open: 'fa-chevron-down',
      remove: 'fa-times'
    }
  }
};
</script>
<script src="/js/adminlte.min.js"></script>

<div class="box box-default collapsed-box">
  <div class="box-header">
    <h3 class="box-title">Notes</h3>
    <div class="box-tools">
      <a class="btn btn-box-tool" href="#">
        <i class="fa fa-plus"></i> Add
      </a>
      <button type="button" class="btn btn-box-tool" data-widget="collapse">
        <i class="fa fa-chevron-down"></i>
      </button>
    </div>
  </div>
  ...
</div>

The expand button above works, but the icon that’s changing is the “plus” one. I’m assuming the AdminLTEOption var is not working anymore like in previous versions?

AdminLTEOptions was removed with v2.4, you can now set simply data attributes to change options. I look over the documentation to display all new options and remove the AdminLTEOptions part.

as of version 2.4.12 AdminLTEOptions is still listed in the documentation, but nowhere in the source. so it seems not to be in use at all.
