React Native's JavaScript bridge was a well-known performance bottleneck for years. Under heavy UI pressure (fast scrolling, frequent re-renders), teams could hit dropped frames and visible "blank" rendering while work moved across threads and through serialization. Meta's New Architecture (JSI, Fabric, TurboModules) changes that baseline. By replacing the legacy bridge with direct, C++-backed interop and a new renderer, React Native closes much of the historical performance gap for many real-world apps.

React, the widely adopted JavaScript library for building user interfaces, has reached a milestone with the stable release of React Compiler 1.0, built on top of nearly a decade of engineering work and compiler learnings that transforms how developers optimize React applications. React Compiler 1.0 is a build-time tool that optimizes React apps through automatic memoization, working on both React and React Native without requiring code rewrites.

React2Shell - CVE-2025-55182 In case you missed my email, a 10.0-scored vulnerability affecting React Server Components was unveiled last week. And it's a really nasty one, enabling unauthenticated remote code execution with a simple HTTP request. Many React meta-frameworks and custom setups are affected, in particular Next.js (v14-canary, v15, v16). If your app is affected, you really need to upgrade now!

Vega, the OS to replace Android, has been built in-house and is based on Linux. It's designed to run across a wide variety of devices and relies on React Native as its application framework. This allows developers to build native apps with JavaScript, with the added benefit that these apps run across a variety of other TV operating systems as well.
