### Scheduler

#### Breaking changes

- The `views` of `EventTimelinePremium` have been renamed to `presets`, with names that describe the header layout. The props `view`/`defaultView`/`views`/`onViewChange` are now `preset`/`defaultPreset`/`presets`/`onPresetChange`, and the type `EventTimelinePremiumView` is now `EventTimelinePremiumPreset`.

| Old      | New            |
| :------- | :------------- |
| `time`   | `dayAndHour`   |
| `days`   | `day`          |
| `weeks`  | `dayAndWeek`   |
| `months` | `monthAndYear` |
| `years`  | `year`         |

CSS variables (`--time-cell-width`, etc.) and headless store state (`state.view`, `setView`) follow the same rename. The `presets` array is now sorted internally against a canonical zoom order.

#### `@mui/x-scheduler@9.0.0-alpha.3`

- [scheduler] Allow creating events via keyboard - EventCalendar (#21967) @rita-codes
- [scheduler] Prefix element IDs with a unique Scheduler instance ID (#22109) @rita-codes

#### `@mui/x-scheduler-premium@9.0.0-alpha.3` [![premium](https://mui.com/r/x-premium-svg)](https://mui.com/r/x-premium-svg-link 'Premium plan')
