The main theme of the React Native keynote was clear: the New Architecture is no longer "new"; it is now simply The Architecture. Riccardo Cipolleschi (Meta) explains that after years of work, it's "time to make it a reality and harvest all the benefits."

This architecture is the foundational block that enables the next generation of React Native features. Cipolleschi outlines how it unlocks:

• Concurrent rendering: Provides the ability to create concurrent rendering paths and manage thread priority.
• New React 19 features: Directly enables features like the <Activity> component to work on native by providing the necessary concurrency support.
• DOM APIs: Serves as the base that allows for the implementation of web-standard DOM APIs on native.
• Hermes V1: Acts as the foundation for Hermes V1 (the new name for Static Hermes).
