**The list of breaking changes:**

BREAKING CHANGE: Update TS typings for `selectedItem` to accept `null` in both `useSelect` and `useCombobox`.

To migrate to the new change, update your types or code if necessary. `selectedItem`, `defaultSelectedItem` and `initialSelectedItem` now have `Item | null` instead of `Item` type. PR with the changes: #1090


BREAKING CHANGE: Update TS typings for `itemToString` to accept `null` for the `item` parameter, in `useSelect` and `useCombobox` + in `Downshift` where this was missing. `useMultipleSelection` type for `itemToString` stays the same as it can't receive `null` as `item`.

To migrate to the new change, update your types or code if necessary. `itemToString: (item: Item) => string` -> `itemToString: (item: Item | null) => string}`. PR with the changes: #1075 #1105


BREAKING CHANGE: Pass `type` to the onChange (onInputValueChange, onHighlightedIndexChange, onSelectedItemChange, onIsOpenChange) handler parameters, as specified in the documentation. Also updated the TS typings to reflect this + `onStateChange` - the `type` parameter was passed but it was not reflected in the TS types.

To migrate to the new change, update your types or code if necessary, better to view the changes in the PR: #985.


BREAKING BEHAVIOUR [useCombobox]: When an item is highlighted by keyboard and user closes the menu using mouse/touch, the item is not selected anymore. The only selection on Blur happens using either Tab / Shift+Tab. PR with the changes: #1109


BREAKING BEHAVIOUR [useCombobox & downshift]: When pressing Escape and the menu is open, only close the menu. When the menu is closed and there is an item selected and/or text in the input, clear the selectedItem and the inputValue. PR with the changes: #719
