+#### CircularProgress deprecated CSS classes removed
+
+Use the [circular-progress-classes codemod](https://github.com/mui/material-ui/tree/HEAD/packages/mui-codemod#circular-progress-classes) below to migrate the code as described in the following section:
+
+```bash
+npx @mui/codemod@latest deprecations/circular-progress-classes <path>
+```
+
+The following deprecated `CircularProgress` CSS classes have been removed:
+
+- `circleDeterminate` → use `.MuiCircularProgress-determinate .MuiCircularProgress-circle`
+- `circleIndeterminate` → use `.MuiCircularProgress-indeterminate .MuiCircularProgress-circle`
+
+If you were using these deprecated class names as `styleOverrides` keys in your theme, use the `variants` array in the `circle` override instead:
+
+```diff
+ const theme = createTheme({
+   components: {
+     MuiCircularProgress: {
+       styleOverrides: {
+-        circleDeterminate: { strokeDashoffset: '10px' },
