## v5.3.0
### Improved markup for progress bars
**We've improved our markup for [progress bars]({{< docsref "/components/progress" >}}).** With our original progress bar structure, bars with a zero value were _not_ announced by some screen readers (NVDA, VoiceOver on iOS). `role="progressbar"` and the relevant `aria-*` attributes are now on the outer `.progress` element, leaving the `.progress-bar` purely for the visual presentation of the bar and optional label. We've also introduced a new `.progress-stacked` class to more logically wrap [multiple progress bars]({{< docsref "/components/progress#multiple-bars" >}}) into a single stacked progress bar.
While we recommend adopting the new markup for improved compatibility with all screen readers, note that the legacy progress bar structure will continue to work as before.
