btn-xs no longer a valid option in bootstrap 4?

Question

I just migrated to bootstrap 4 and my xs buttons no longer seem to be extra small!

Looking at the docs for buttons in bootstrap 4 I don't see the option for extra small buttons?

Can anyone confirm this for me?

Thanks!

@rifton007 posted a quick fix in the GitHub issue on this subject. Add this in your css file:

.btn-group-xs > .btn, .btn-xs {
  padding: .25rem .4rem;
  font-size: .875rem;
  line-height: .5;
  border-radius: .2rem;
}

Demo:

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet"/>

<style>
.btn-group-xs > .btn, .btn-xs {
  padding: .25rem .4rem;
  font-size: .875rem;
  line-height: .5;
  border-radius: .2rem;
}
</style>

<button class="btn btn-primary btn-xs">♡</button>
<button class="btn btn-primary btn-sm">♡</button>
<button class="btn btn-primary">♡</button>
<button class="btn btn-primary btn-lg">♡</button>
