- React Native 0.88: events dispatch through EventTarget, Text gets variable fonts, and iOS apps move to SceneDelegateReact Native 0.88 shipped on October 19, 2026 with React 19.3.0 and Metro 0.87. Events now run through the W3C EventTarget path, fontVariationSettings works on Text and TextInput, and RCTReactNativeFactory gains SceneDelegate entry points ahead of Apple's iOS 27 SDK requirement. No user-facing breaking changes.
- The React Foundation launches: Meta hands React to eight members and the Linux FoundationOn February 24, 2026, Meta stopped owning React, React Native and JSX. The React Foundation, hosted by the Linux Foundation with eight Platinum members and Seth Webster as executive director, now holds them, and a separate council sets technical direction.
- React Server Components advisories: build a patch laneCVE-2025-55182 let an unauthenticated request run code on any server that supports React Server Components, with a CVSS of 10.0. Researchers probing the fix found three denial-of-service bugs and a source leak over the next eight weeks. This post covers the timeline and a response plan that holds up when the next patch is also incomplete.
- React Conf 2025: a stable compiler, a foundation and React Native at 4M weekly downloadsReact Conf 2025 ran October 7 and 8 in Henderson, Nevada. The React team shipped Compiler 1.0, previewed ViewTransition and Fragment refs, announced the React Foundation, and reported React Native at 4 million weekly downloads.
- React Compiler 1.0: roll it out like a migrationReact Compiler 1.0 went stable on October 7, 2025, after Meta measured up to 12% faster loads and interactions over 2.5x faster on the Quest Store. Lint first, compile one directory, gate it behind a flag, and pin the version.
- React 19.2: Activity, useEffectEvent, performance tracks and partial pre-renderingReact 19.2 shipped on October 1, 2025 with Activity for hidden UI that keeps state, useEffectEvent for effect logic that reads fresh values, Chrome DevTools performance tracks, partial pre-rendering and a new useId prefix.
- React state without the noiseDerive what you can, store what changes, and keep effects for the systems React doesn't own.
- React.dev as a product resetThe 2023 docs relaunch treated documentation as a product surface. The same moves cut cognitive load in any front end.
- Components as product boundariesDesign a React component around the product decision it owns. Reuse follows from that, and review gets easier.
