Highcharts Core （英語版） リリース

• Added new options set, palette, making it easy to apply general design colors for light and dark mode. This replaces the former Adaptive theme.
• Added support for providing data as DataTable through the new options dataTable, series.dataTable and series.dataMapping.
• Updated gauge and solid-gauge series, including panes and radial y-axis, with more sensible defaults and major design facelift, making it easier for implementers and AI agents to create great looking gauges from minimal configuration.
• Refactored the data sorting functionality into a separate module, in order to simplify and reduce weight on the core script file.
• Improved entrance and exit animation of points and data labels when they are dynamically created, destroyed or zoomed in or out of view.
• Added the experimental autoload feature, loading required modules based on the chart configuration.
• Added customizable boundary ticks for datetime axes.
• Added new setting, contrast, for dataLabels.backgroundColor. Allows enhancing readability with a plain, semi-transparent background color. Extended the dataLabels.distance option to apply to more series types than previously.
• Added new option, chart.plotBorderRadius.
• Added new options set, tooltip.header, for better control over the header design in split tooltips.

Upgrade notes:

• Default pane layout and design for gauges and polar charts has gone through a major facelift.
• Solid gauge radius and innerRadius, when given as numeric values, defined on series or point level, no longer resolve as percents, but as pixels. To set it to a percent, use a percentage string like radius: '50%'.
• The dataSorting feature now requires the modules/data-sorting.js file.
• Default data label positions have changed slightly. Previously, the distance to the point or column was determined by padding and adjusted by x and y. Introduced new option, dataLabels.distance, in order to allow backgrounds with padding without touching the point.

• Fixed, boosted points were missing keyed values after zoom.
• Fixed, in the exporting menu, the 'View in fullscreen' label was broken after being used.
• Fixed, fixed and split tooltip with useHTML shifted after first render.
• Fixed, templating multiply helper exposed floating-point precision in axis labels.
• Fixed, grid lines rendered above the plot border after responsive axis update.
• Fixed, exported charts did not have correct data after updating it with null values.
• Fixed, styled mode x-range missed colorIndex after setData.
• Fixed, year resolution date labels didn't respect localized format.
• Fixed, consistent chart menu aria-label and i18n translations.
• Fixed, regression with zones set below max value and axis max set, line on max was clipped.

• Added support for dendrograms by allowing treegraph charts to be plotted against an x-axis.
• Added new option, legend.maxWidth.
• Added the color-scheme CSS property across CSS files and Adaptive theme, to allow setting any color with the light-dark() CSS function.
• Added a warning when chart.styledMode is enabled and the required CSS file is not loaded.

• Fixed the last four of the default pattern fill definitions which had undefined color.
• Fixed SeriesRegistry which was unavailable in custom ESM bundle because of circular import.
• Fixed tooltip header which was rendered incorrectly for Chinese and other non-latin scripts.
• Fixed tooltips with stickOnContact which now remain visible when the cursor leaves a point and re-enters the tooltip container within hideDelay.
• Fixed points in boosted chart with zones that had the wrong color when not within a zone.
• Fixed pie data labels which were misplaced after a chart size change.
• Fixed a regression in templating which was causing bad formatting of decimal timestamps.
• Fixed boosted series color which was wrong after updating to empty zones.
• Fixed tooltip which was not rendering for heatmap cell on hover after dataClass legend toggle.
• Fixed axis names which weren't translated in screen reader output.
• Fixed gauge clip box which was incorrect when the pane position was close to the edge of the chart.
• Fixed dataLabels.zIndex which was ignored, so labels could render above series regardless of the setting.
• The Adaptive theme didn't work in Shadow DOM.
• Disabled markers were appearing after zooming out when the accessibility module was loaded and the chart was in styled mode.
• The chart.alignThreshold option did not always take effect after zooming.
• Updating series with multiple data labels failed.
