+---
+
+As of Home Assistant Core 2022.5, `CalendarDeviceEntity` is deprecated and superseded by `CalendarEntity`. The new entity has a more well defined data model, and a streamlined websocket API. `CalendarDeviceEntity` will be removed in a future Home Assistant release and custom components are required to migrate to the new APIs. See the new [Calendar Entity](https://developers.home-assistant.io/docs/core/entity/calendar) developer documentation for details.
