Mar 1, 2026

March 2026 highlights a strategic architectural consolidation, targeted platform enhancements, and improved governance. Key work includes migrating a broad set of FiberElement helpers, render-tree utilities, and parent/component logic into the Element base to enable cross-type reuse and pave the way for unified rendering. On iOS CUI, we closed critical platform gaps by adding SubtreeProperties support for Transform/Opacity, implementing kBorder and kClipRect in the DisplayListApplier, and hardening non-flatten CSS handling and text overflow behavior. Documentation and hygiene were strengthened with extensive AGENTS guides for core and renderer layers, and the codebase was cleaned up by removing unused Air sources/build configurations. These efforts together improve performance potential, stability, and developer velocity while delivering concrete business value around reliability, parity across platforms, and easier future maintenance.

Dec 1, 2025

Summary for 2025-12 (lynx-family/lynx): Delivered major UI/DevTools and architecture improvements that boost rendering performance, cross-platform consistency, and developer productivity. Implemented UI primitive exposure and view-to-screen transform for the Android DevTool box model, added ListFragmentBehavior and kList renderer type with default-native list rendering in Fragment, and enabled the new animator and unified rendering pipeline by default for fragment-layer rendering. Architectural refactors established a stronger, more maintainable base by unifying the CFunction signature to argv/argc across Lepus/Renderer, and extracting a standalone LayoutScheduler interface with cross-TASM integration. These changes unlock faster iteration, clearer interfaces, and groundwork for cross-platform painting contexts and future performance improvements.
