 * **BREAKING** Charts touchCallback signature has changed to `(FlTouchEvent event, BaseTouchResponse? response)` which [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) determines which touch/pointer event happened (such as `FlTapUpEvent`, `FlPanUpdateEvent`, ...), and BaseTouchResponse gives us the chart response.
 * **BREAKING** Chart touchResponse classes don't have `touchInput` and `clickHappened` properties anymore. Use [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) provided in the callback instead of `touchInput`. Check `event is FlTapUpEvent` to detect touch events instead of checking `clickHappened`;
 * **IMPROVEMENT** Again we support `longPress` touch events. check [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) to see all kind of supported touch/pointer events (which can be `FlLongPressStart`, `FlLongPressMoveUpdate`, `FlLongPressEnd`, ...). Also you can check out [touch handling doc](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/handle_touches.md), #649.
-* **IMPROVEMENT** Added `mouseCursorResolver` callback in touchData classes such as [LineTouchData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/line_chart.md#linetouchdata-read-about-touch-handling) and [BarTouchData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#bartouchdata-read-about-touch-handling). You can change the [MouseCursor](https://api.flutter.dev/flutter/services/MouseCursor-class.html) based on the provided [FlTouchEvent](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#fltouchevent) and touchResponse using this callback.

 ## 0.36.4
 * **IMPROVEMENT** Added `borderSide` property in [BarChartRodData](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#BarChartRodData) and [BarChartRodStackItem](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/bar_chart.md#BarChartRodStackItem) to draw strokes around each bar and rod stack items, #714.
