### Scheduler

#### Breaking changes

- The `dataSource` prop has been removed from the Community Event Calendar components:
  `EventCalendar`, `StandaloneDayView`, `StandaloneWeekView`, `StandaloneMonthView`,
  `StandaloneAgendaView`, `StandaloneCompactDayView`, `StandaloneCompactThreeDayView` and
  `StandaloneCompactWeekView`.

  Lazy loading has always been Premium-only, and the prop never had any effect on these
  components: it left the calendar in a permanent loading state. To load events through a data
  source, use `EventCalendarPremium` (or the Premium standalone views) and `EventTimelinePremium`,
  where `dataSource` is unchanged.

  ```diff
  -import { EventCalendar } from '@mui/x-scheduler/event-calendar';
  +import { EventCalendarPremium } from '@mui/x-scheduler-premium/event-calendar-premium';

  -<EventCalendar dataSource={dataSource} />
  +<EventCalendarPremium dataSource={dataSource} />
  ```
