v11.1.0

Version 11.1.0

Framework:

2. Added the heatmap.interpolation option for creating smooth heatmaps.
3. Added new function, Chart.getOptions(), to get the current active configuration options for the chart.
4. Added the treegraph.fillSpace option for treegraphs to fill the whole plot area even when some points are collaped.
5. Added borderRadius option support for funnel and pyramid series. See #18839.
6. Added new option, xAxis.crossing and yAxis.crossing, making it easier to create axis layout for mathematical plots.
7. Added new option, series.legendSymbol. See #18753.
8. Design facelift with clearer, more vivid palette, added contrast for text labels and many minor visual changes.
9. Added new series type, treegraph. Read more in the docs.
10. Added new series type, pictorial.
11. Removed support for IE 8 and older.
12. Changed the default builds to ECMAScript version ES2016.
13. Replaced SASS files for styledMode with updated CSS files. Highcharts theming is now easier by supporting CSS variables as well as prefers-color-scheme. See style by CSS.

Framework upgrade notes:

1. To revert to the old design, use the theme defined in the v10 theme sample.
2. Font sizes of the chart are now using rem by default. This may cause too small or too big fonts if your web page is using non-default root element font size. To avoid that, set chart.style.fontSize to 16px or any other values you see fit.
3. The top-level labels option has been deprecated for a long time and is now removed. Use Annotations instead.
4. Time-related settings on the global options structure are removed. Use the time options instead.

6. The default builds were changed to ECMAScript version ES2016. See the system requirements on how to support IE11 and other legacy browsers.
7. If you're using chart.styledMode, and your end users have prefers-color-scheme set to dark in their browsers, they may now be presented with dark-themed charts. The exception is if your CSS overrides the default coloring.
8. Changed default rotationMode to circular for sunburst data labels.
