2. Remove any usages of `pickerController`. If using React, remove any usages of the `useIonPicker` hook. These controller-based APIs have been removed in Ionic 9. Use the [Picker](../api/picker.md) component instead.
3. Remove any usages of the `PickerOptions`, `PickerButton`, `PickerColumn`, and `PickerColumnOption` type exports. These types were associated with the legacy picker and have been removed in Ionic 9.

### Select

The `ionChange` event on `ion-select` now only fires when the value changes. Previously, the `alert` and `action-sheet` interfaces emitted `ionChange` whenever the overlay was confirmed, even if the user picked the option that was already selected. This matches the documented behavior and the existing behavior of the `popover` and `modal` interfaces.

If your code relied on `ionChange` firing on every confirmation (for example, to detect that the user closed the overlay without changing anything), listen for `ionDismiss` instead, or use the `didDismiss` event on the underlying alert or action sheet.
