5.17.3

[5.17.3] - 2026-05-29

Added

• Label setting fontFamily now accepts special value of "inherit". If set it will automatically use computer fontFamily value on chart's DOM container.
• onDebounced(key, callback, delay) and offDebounced(key, callback?) methods added to all entities. Like on()/off() for settings, but the callback fires only once after rapid changes settle, waiting delay milliseconds since the last change.
• onPrivateDebounced(key, callback, delay) and offDebouncedPrivate(key, callback?) — same as above for private settings.

Fixed

• The underline text for a Label could render thicker in some cases.
• GanttSeries was not syncing the end field back to data context when tasks were moved or resized, causing stale values when serializing data or calculating linked group positions.
• Gantt.addNewTask() was setting a hardcoded stale end value in new task data.
• If Root was placed in a ShadowDOM, TAB would select non-visible focusable elements.
• Accessibility: The text for readable tooltip element had in-line formatting text in them.
