+{productname} {release-version} adds the `+tinymce.dom.AriaAnnouncer+` API for sending messages to screen readers through an `+aria-live+` region without shifting focus. The `+announce+` method accepts a message and an optional `+{ assertive }+` setting. Integrators can use it to announce formatting changes, for example by listening to the `+FormatApply+` and `+FormatRemove+` events.
