+# Migrate plugins from Grafana version 10.0.x to 10.1.x
+
+## Accessibility update for IconButton component in grafana-ui
+
+We updated the component's TypeScript interface due to an accessibility issue. This change was delivered to the core `grafana` repo with [PR 69699](https://github.com/grafana/grafana/pull/69699).
+
+In case you are using the IconButton component in your plugin you will get TypeScript errors related to the change.
+
+**Recommended actions:**
+
+- Review use cases of IconButton in your plugin.
+- Add a meaningful tooltip which the component will also use as an aria-label.
+- Another option is to set an aria-label. In this case a tooltip will not be shown.
+
+**Please note:**
+The IconButton used to have a property called `ariaLabel` which got deprecated with this change. You can now use the regular property `aria-label` instead.
