Versions 1.15.9 and 1.16.2 have been released.
These versions contains a workaround for Chrome 55 and newer to keep the page scrolling experience with touch the same as previous versions.
Chrome 55+ includes support for PointerEvent specification that our library has always supported. However PointerEvent cannot be canceled in the same way as TouchEvent thus they prevented scrolling of the page when the user swipes non-interactive areas of the chart (such as the vertical axis for TimeChart or empty area for PieChart).
