Changelog

Version 2.2.7

Released 23 Jun 2026

API	Getters for data-binding model properties used in complex data-binding expressions are evaluated only once per model synchronization.
API	Complex data-binding expressions with side effects are evaluated only once per synchronization.
Feature	Added support for numerical value comparison in a custom media feature.
Enhancement	Improved style inheritance performance by optimizing inheritance resolution and reducing styling overhead.
Enhancement	Improved styling performance for custom variables by reducing recalculation costs.
Enhancement	Improved styling performance for SVG-heavy content by reducing the cost of processing large numbers of inline SVG elements.
Enhancement	Improved rendering performance by optimizing visual style calculations for large layout trees.
Enhancement	Improved transform update performance by reducing processing overhead across large layout trees.
Enhancement	Optimized repeated data-binding expressions by evaluating them once per synchronization.
Enhancement	Reduced the magnitude of spikes caused by garbage collection tracing.
Enhancement	Optimized `data-bind-value` by 25% when the underlying property has not changed.
Enhancement	Reduced copies and allocations when getting string property values from data-binding models.
Enhancement	Improved data-binding performance by optimizing expression evaluation during model synchronization.
Enhancement	Improved content update performance by avoiding unnecessary HTML parsing for simple text updates when using innerHTML
Fix	Fixed a crash when calling `caretPositionFromPoint` for inline SVG.
Fix	Fixed incorrect spacing and an assert when composed characters without matching font glyphs are drawn.
Fix	Fixed accumulation of `DOMRect` instances until the next major garbage collection.
Fix	Fixed a layout regression related to single flex-child height calculation.
Fix	Fixed garbage collection of custom elements when they are not attached to the DOM but have reactions to be invoked.
Fix	Fixed cases where SVG animations would fail to restart after being hidden.
Fix	Fixed cases in which the layout of :after pseudo elements would be incorrect.
Fix	Resolved warnings caused by HTML or SVG parsing errors.
Fix	Fixed incorrect draw order of text decorations.
Fix	Fixed an assert in the player when scrolling with high-precision mice.
