January 2025 — Focused on delivering a core architectural simplification for React Native layout animations.

This reduces runtime toggles, simplifies developer experience, and improves cross-platform consistency. Key commit: 44da5d2ee07d06a0e11b626e2641e255f0ffde9f (Make setLayoutAnimationEnabledExperimental a no-op in Bridgeless (#48856)).
