Upgarde to HighchartsJS 11.2.0

[eastclintw00d]

Highcharter currently uses HighchartsJS 10.2.0

Is there a chance to switch to the latest release? There are interesting features like more customizable dumbbell charts.

Please update HighchartsJS, I'm trying to use treegraph series but it's not compatible with the current Highcharter because it was introduced in HighchartsJS V11....

I would also like to implement the treegraph series. Is there a plan to upgrade to newer versions of highcharts?
