Mar 1, 2026March 2026 focused on privacy and WebView improvements in Samsung/TizenFX by delivering incognito mode awareness across WebView context and cookie management. The work adds an incognito flag to relevant APIs to enforce privacy boundaries, enabling safer private sessions and reducing cross-context data leakage. A binder-side integration patch was prepared (commit 850889b742aa695828a017be85a641ab48c173f8) with related Gerrit review, enabling cross-component privacy enforcement. This foundation positions the project to meet evolving privacy requirements and facilitates future enhancements. No major bug fixes were recorded for Samsung/TizenFX in this period.

Feb 1, 2025February 2025 performance highlights for Samsung/TizenFX: delivered XAML optimization to reduce overhead by conditionally disabling XAML parsing and internal property setters when XAML is not used, across NUI and NUI.Components. Adopted a new StyleProperty system to unify style handling across UI components, replacing BindableProperty and including ViewStyle improvements (e.g., z/depth) for better maintainability and potential performance gains. Implemented memory management and stability improvements, addressing memory leaks in Vector4, Size2D, and Rectangle handling, and removing boxing/unboxing in View to reduce GC pressure. Fixed critical crashes related to applying ViewStyle and setting layouts on Views. These changes enhance startup performance for non-XAML apps, improve UI styling reliability, and boost runtime stability for long-running applications.
