I'm very excited about this release. It allows the module to provide custom settings per library+chart type. An example of this is that when a user uses Highcharts and selects a bar/column type, they now have an option (in Views or the Chart Field) to check a box to enable "stackLabels" (the total of a stacked column shown at the top of the column). There are two other Highcharts options taking advantage of this: the option for solid gauge charts and the ability to use "colorAxis" on pie/donut charts,.
