Section
Fixes
- Fixed a Safari 17 modal focus issue where the focus trap could escape when custom overlays and sticky headers were used together.
- Resolved a React 19 hydration mismatch in
<Tooltip>by deferring tooltip content until the component mounts. - Patched a
<DataTable>crash whenrowsis undefined on the initial render so it now falls back to an empty state.
Section
Improvements
- Reduced bundle size by 23% by tree-shaking unused icon imports from the
prismatic-ui/iconssubpath. - Switched internal color calculations from hex to
oklch, improving theme token resolution speed and color consistency.
