Full Fact Overview
React 19.3 represents a significant update to the core library, focusing on modern browser API integration and DOM manipulation ergonomics. The inclusion of View Transitions allows for native-level animation handling, while Fragment Refs resolve a long-standing limitation regarding the inability to attach refs directly to React Fragments. The addition of Trusted Types support indicates a strategic shift toward stricter security postures for enterprise applications, and the browser() utility provides a standardized way to detect execution environments.
