In previous years, we've used the React Conf stage to deliver industry changing announcements such as React Native and React Hooks. This year, we shared our multi-platform vision for React, starting with the release of React 18 and gradual adoption of concurrent features. This was the first time React Conf was hosted online, and it was streamed for free, translated to 8 different languages.

This means there is no concurrent mode, only concurrent features. In the keynote, we also shared our vision for Suspense, Server Components, new React working groups, and our long-term many-platform vision for React Native.
