+<Intro>
+
+Last week we hosted React Conf 2025 where we announced the [React Foundation](/blog/2025/10/07/introducing-the-react-foundation) and showcased new features coming to React and React Native.
+
+</Intro>
+
+---
+
+React Conf 2025 was held on October 7-8, 2025, in Henderson, Nevada.
+
+The entire [day 1](https://www.youtube.com/watch?v=zyVRg2QR6LA&t=1067s) and [day 2](https://www.youtube.com/watch?v=p9OcztRyDl0&t=2299s) streams are available online, and you can view photos from the event [here](https://conf.react.dev/photos).
+
+In this post, we'll summarize the talks and announcements from the event.
+
+
+## Day 1 Keynote {/*day-1-keynote*/}
+
+_Watch the full day 1 stream [here.](https://www.youtube.com/watch?v=zyVRg2QR6LA&t=1067s)_
+
+In the day 1 keynote, Joe Savona shared the updates from the team and community since the last React Conf and highlights from React 19.0 and 19.1.
+
+Mofei Zhang highlighted the new features in React 19.2 including:
+* [`<Activity />`](https://react.dev/reference/react/Activity)  — a new component to manage visibility.
+* [`useEffectEvent`](https://react.dev/reference/react/useEffectEvent) to fire events from Effects.
+* [Performance Tracks](https://react.dev/reference/dev-tools/react-performance-tracks) — a new profiling tool in DevTools.
+* [Partial Pre-Rendering](https://react.dev/blog/2025/10/01/react-19-2#partial-pre-rendering) to pre-render part of an app ahead of time, and resume rendering it later.
+
+Jack Pope announced new features in Canary including:
+
+* [`<ViewTransition />`](https://react.dev/reference/react/ViewTransition) — a new component to animate page transitions.
+* [Fragment Refs](https://react.dev/reference/react/Fragment#fragmentinstance) — a new way to interact with the DOM nodes wrapped by a Fragment.
+
+Lauren Tan announced [React Compiler v1.0](https://react.dev/blog/2025/10/07/react-compiler-1) and recommended all apps use React Compiler for benefits like:
+* [Automatic memoization](/learn/react-compiler/introduction#what-does-react-compiler-do) that understands React code.
+* [New lint rules](/learn/react-compiler/installation#eslint-integration) powered by React Compiler to teach best practices.
+* [Default support](/learn/react-compiler/installation#basic-setup) for new apps in Vite, Next.js, and Expo.
+* [Migration guides](/learn/react-compiler/incremental-adoption) for existing apps migrating to React Compiler.
+
+Finally, Seth Webster announced the [React Foundation](/blog/2025/10/07/introducing-the-react-foundation) to steward React's open source development and community.
