 - **Progress bars**
   - The markup for [progress bars]({{< docsref "/components/progress" >}}) has been updated in v5.3.0. Due to the placement of `role` and various `aria-` attributes on the inner `.progress-bar` element, **some screen readers were not announcing zero value progress bars**. Now, `role="progressbar"` and the relevant `aria-*` attributes are on the outer `.progress` element, leaving the `.progress-bar` purely for the visual presentation of the bar and optional label.
