### Scheduler

#### Breaking changes

The theme `styleOverrides` slots for the skeleton and the error container were
renamed and unified. The CSS utility class names (for example
`.MuiEventCalendar-eventSkeleton`) are **not** affected — only
`theme.components.*` overrides need updating.

**Event skeleton**

| Before                                  | After                          |
| --------------------------------------- | ------------------------------ |
| `MuiEventCalendar` slot `EventSkeleton` | `MuiEventSkeleton` slot `Root` |
| `MuiEventTimeline` slot `EventSkeleton` | `MuiEventSkeleton` slot `Root` |

**Error container**

| Before                                                        | After                                   |
| ------------------------------------------------------------- | --------------------------------------- |
| `MuiEventCalendar` / `MuiEventTimeline` slot `ErrorContainer` | `MuiEventErrorContainer` slot `Root`    |
| `MuiEventCalendar` / `MuiEventTimeline` slot `ErrorAlert`     | `MuiEventErrorContainer` slot `Alert`   |
| `MuiEventCalendar` / `MuiEventTimeline` slot `ErrorMessage`   | `MuiEventErrorContainer` slot `Message` |

If you customized these through the theme, update the component name and slot
names accordingly:

```diff
 components: {
-  MuiEventCalendar: {
+  MuiEventSkeleton: {
     styleOverrides: {
-      EventSkeleton: { /* ... */ },
+      Root: { /* ... */ },
     },
    },
  },
 }
```

### 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
