+## newVersion
+* **BUGFIX** Fix `FlSpot.nullSpot` at the first of list bug, #912.
+* **FEATURE** Add `tooltipBorderColor` and `tooltipBorderWidth` property in the [LineTouchTooltipData], [BarTouchTooltipData], [ScatterTouchTooltipData],  #692.
+
+## 0.45.0
+* **BUGFIX** Fix `clipData` implementation in ScatterChart and LineChart, #897.
+* **BUGFIX** Fix PieChart changing sections issue (we have disabled semantics for pieChart badgeWidgets), #861.
+* **BUGFIX** Fix LineChart width smaller width or height lower than 40, #869, #857.
+* **BUGFIX** Allow to show title when axis diff is zero, #842, #879.
+* **IMPROVEMENT** Improve iteration over axis values logic (it solves some minor problems on showing titles when min, max values are below than 1.0).
+* **IMPROVEMENT** Add `baselineX` and `baselineY` property in our axis-based charts, It fixes a problem about `interval` which mentioned in #893 (check [this sample](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/line_chart.md#gist---baselinex-baseliney-sample-source-code).
+* **IMPROVEMENT** Added `distanceCalculator` to `LineTouchData` which is used to calculate the distance between spots and touch events, #716, #261, #892
+* **BREAKING** `LineTouchResponse` response now contains a list of `TouchLineBarSpot` instead of `LineBarSpot`. They are ordered based on their distance to the touch event and also contain that distance.
+
 ## 0.41.0
 * **BUGFIX** Fix getNearestTouchedSpot. Previously it returned the first occurrence of a spot within the threshold, and not the nearest, #641, #645.
 * **FEATURE** Add `textAlign` property in the [SideTitles](https://github.com/imaNNeoFighT/fl_chart/blob/master/repo_files/documentations/base_chart.md#sidetitles), #784.
