• FEATURE (by @​Peetee06) Implemented a 5 years-old feature request about scroll and zoom support in our axis-based charts. Special thanks to @​Peetee06 who made it happen, #​71
• IMPROVEMENT (by @​Peetee06) Added functionality to control the transformation of axis-based charts using FlTransformationConfig class. You can now enable scaling and panning for LineChart, BarChart and ScatterChart using this class

• BREAKING (by @​Peetee06) BarChart is not const anymore due to adding an assert to check if transformations are allowed depending on the BarChartData.alignment property (read more here)
