#### Button deprecated CSS classes removed

Use the [button-classes codemod](https://github.com/mui/material-ui/tree/HEAD/packages/mui-codemod#button-classes) below to migrate the code as described in the following section:

```bash
npx @mui/codemod@latest deprecations/button-classes <path>
```

The following deprecated `Button` CSS classes have been removed:

- `textInherit` → use `.MuiButton-text.MuiButton-colorInherit`
- `textPrimary` → use `.MuiButton-text.MuiButton-colorPrimary`
- `textSecondary` → use `.MuiButton-text.MuiButton-colorSecondary`
- `textSuccess` → use `.MuiButton-text.MuiButton-colorSuccess`
- `textError` → use `.MuiButton-text.MuiButton-colorError`
- `textInfo` → use `.MuiButton-text.MuiButton-colorInfo`
- `textWarning` → use `.MuiButton-text.MuiButton-colorWarning`
- `outlinedInherit` → use `.MuiButton-outlined.MuiButton-colorInherit`
- `outlinedPrimary` → use `.MuiButton-outlined.MuiButton-colorPrimary`
- `outlinedSecondary` → use `.MuiButton-outlined.MuiButton-colorSecondary`
- `outlinedSuccess` → use `.MuiButton-outlined.MuiButton-colorSuccess`
- `outlinedError` → use `.MuiButton-outlined.MuiButton-colorError`
- `outlinedInfo` → use `.MuiButton-outlined.MuiButton-colorInfo`
- `outlinedWarning` → use `.MuiButton-outlined.MuiButton-colorWarning`
- `containedInherit` → use `.MuiButton-contained.MuiButton-colorInherit`
- `containedPrimary` → use `.MuiButton-contained.MuiButton-colorPrimary`
- `containedSecondary` → use `.MuiButton-contained.MuiButton-colorSecondary`
- `containedSuccess` → use `.MuiButton-contained.MuiButton-colorSuccess`
- `containedError` → use `.MuiButton-contained.MuiButton-colorError`
- `containedInfo` → use `.MuiButton-contained.MuiButton-colorInfo`
- `containedWarning` → use `.MuiButton-contained.MuiButton-colorWarning`
- `textSizeSmall` → use `.MuiButton-text.MuiButton-sizeSmall`
- `textSizeMedium` → use `.MuiButton-text.MuiButton-sizeMedium`
- `textSizeLarge` → use `.MuiButton-text.MuiButton-sizeLarge`
- `outlinedSizeSmall` → use `.MuiButton-outlined.MuiButton-sizeSmall`
- `outlinedSizeMedium` → use `.MuiButton-outlined.MuiButton-sizeMedium`
- `outlinedSizeLarge` → use `.MuiButton-outlined.MuiButton-sizeLarge`
- `containedSizeSmall` → use `.MuiButton-contained.MuiButton-sizeSmall`
- `containedSizeMedium` → use `.MuiButton-contained.MuiButton-sizeMedium`
- `containedSizeLarge` → use `.MuiButton-contained.MuiButton-sizeLarge`
- `iconSizeSmall` → use `.MuiButton-root.MuiButton-sizeSmall > .MuiButton-icon`
- `iconSizeMedium` → use `.MuiButton-root.MuiButton-sizeMedium > .MuiButton-icon`
- `iconSizeLarge` → use `.MuiButton-root.MuiButton-sizeLarge > .MuiButton-icon`

If you were using these deprecated class names as `styleOverrides` keys in your theme, use the `variants` array in the `root` override instead:

```diff
