• Feat: Add experimental_adaptiveRender with useAdaptiveRender and useAdaptiveRenderChange, so item components can render a lighter version while the list is moving quickly and return to normal after scrolling slows.
• Feat: Add setItemSize to the list ref for updating a known item's measured size directly when its content changes outside normal layout measurement.
• Fix: Web maintainVisibleContentPosition keeps the intended anchor when headers change, browser scroll anchoring runs, or an animated scrollToEnd is already in progress. #468 #463
• Fix: initialScrollIndex and initialScrollAtEnd use the latest initial scroll props when data starts empty and loads later, so lists do not scroll to an old startup target.
• Fix: Changing gap now refreshes cached item measurements, and fixed-size rows include the gap in their positions.
• Fix: SectionList sticky headers update after the section data changes. #445
• Fix: Horizontal lists with end alignment now place items at the end instead of ignoring the alignment. #472
• Fix: Lists clear scheduled timers on unmount, preventing delayed adaptive-render or scroll work from running after the list is gone.
• Perf: The first render starts with a smaller draw distance and expands shortly after, reducing offscreen work before the initial content appears.
• Perf: alignItemsAtEnd spacer updates cause fewer ScrollView rerenders.
• Types: Export AdaptiveRender and AdaptiveRenderConfig from the React Native and web type entrypoints.
