v12.2.0 での更新項目

機能

• Added support for native color-mix. This means colors don't have to be parsed and analyzed in order to allow tweening and modification. Which means full support for CSS variables, named colors and all color definitions known to the browser.
• Added experimental flag, HTMLElement.useForeignObject. When true, labels with the useHTML flag are rendered inside a <foreignObject> in SVG, instead of the traditional parallel div structure.
• Added ESM bundles for dynamic imports. Use highcharts/esm/highcharts.js or load from the Highcharts CDN.
• Added new options, tooltip.fixed and tooltip.position, as a simple declarative way of keeping the tooltip fixed.
• Added the nullInteraction option for more series types than before. Null points will now support data labels and tooltips.
• Added language modules for some selected languages, as well as a structure to continue building on.
• Added level headers in treemap as separate cells through the dataLabels.headers option. Followed up with improved layout control with the new treemap.groupPadding and treemap.nodeSizeBy options.
