The New Architecture is officially not so new anymore. Riccardo Cipolleschi from the Meta core team explains why it's now just "The Architecture" and how it's the foundation for every major update announced at React Conf.

He details how this shift (in progress since 2018) is finally ready to "harvest the benefits," enabling:

➡️ Concurrent rendering paths
➡️ Hermes V1 (formerly Static Hermes)
➡️ DOM APIs on native
➡️ New React 19 features (like the `Activity` component)

Learn how this base layer makes the future of React Native possible.
