What’s New in React Native 0.83: Latest Features You Should Know (2026 & Beyond)

Key Highlights of React Native Latest Version:

• This release includes React 19.2, bringing new features like and useEffectEvent APIs.
• New Devtools introduced with network and performance panels and a new desktop app.
• Intersection Observer (canary) aids the app to learn the appearance and disappearance of the sections on the screen.
• Stable web performance APIs.
• React Native Expo SDK 55 is supported by the React Native 0.83 release.

On December 10, 2025, React Native released its latest version 0.83. Developed by Meta and the community, React Native initially released on March 26, 2015. Since its inception, this cross-platform mobile app development solution has established itself as a major technology for mobile app solutions.

Today, React Native is used for social media and communication apps, Ecommerce applications, on-demand services, enterprise and data-heavy dashboards and more. With growing demand for mobile apps and tech stack, React native has released its latest version to enhance the development process and help developers.

Here, in this blog, let’s understand what React native 0.83 release is, what’s new in this React Native 0.83, and how to upgrade to React Native 0.83

React Native 0.83:

React Native is a UI software framework developed by Meta (Facebook) to develop cross-platform applications and React Native 0.83 is a specific version introduced by the Meta community to optimize the framework.

What’s New in React Native 0.83

1. <activity> and useEffectEvent APIs

This release integrates React latest version 19.2, which brings features like and useEffectEvent to accelerate proficiency. has two modes ‘visible’ and ‘hidden’ and useEventEffect splits the “event” part to ensure no surrounding effect re-runs the process.
For instance, in a React Native Ecommerce application, can be used on a product-related screen to make certain sections hidden in the app when they are not visible. When marked as a ‘hidden’ component, it preserves its state and when the user navigates the screen activity becomes ‘visible’, enabling the UI to appear instantly without remounting.

useEffectEvent splits the Event logic out of Event by enabling a lint rule, eliminating unnecessary re-runs. It solves common glitches like analytics getting stuck on old data by creating a stable tracker. In a React Native Ecommerce app, if a user adds a product to the cart switches and theme(like dark mode), a regular useEffect will restart every time and send outdated numbers, while useEffectEvent eliminates unnecessary API hits and provides real-time dashboard insights.

2. New devtools

The internal activities of React Native applications are monitored, managed, error detection and solved by the devtools. New devtools features like the network & performance panel and new desktop app have streamlined the development process. For instance, in a production React Native banking app, network panels reveal GraphQL queries (slow calls) to the server and direct straight to the problem in the code.

Performance tracing via a desktop app allows developers to detect slow parts, fix bugs within minutes, and optimize the application. It provides a slow-motion replay of JavaScript working to identify and resolve problems faster.

3. Intersection Observer(Canary)

Intersectionobserver browser API in the Canary release for React Native 0.83 observes intersection layout between target elements and their ancestors. It notifies when an element enters or exits the visible area(screen). This allows elements to load on the screen when needed.

For example, imagine a user scrolling through the social media React Native app that contains texts, images, and videos. In some cases, without an Intersection Observer, the app will load everything at once when the user opens the app, which leads to slow load, high memory usage, and performance constrained. The intersection observer will observe each post component and notify when the post enters the screen, so that images start downloading and videos can autoplay and notify again when the post exits the screen, so that videos can pause and heavy resources are released.

4. Stable Web Performance APIs

React Native implements a subset of web performance APIs as stable. This includes high-resolution times, performance timeline, user timing, event timing API, and long tasks API. These APIs track different aspects of performance in your app via React Native devtools.

For instance, a user has opened a food delivery React Native app and customers are complaining that the app feels slow while opening the home screen. As a developer, you can use React Native devtools and stable performance APIs to measure and fix issues. Like

• High resolution time – performance.now()
  You can find out what takes long for home screen rendering.

• Performance timeline – PerformanceObserver
  It shows you different renderings and JS execution to detect large gaps in JS execution.

• User timing – performance.mark – performance.measure
  Using marks like home_screen_start and home_screen_rendered helps you find out which step is slow.

• Event Timing API – event
  You notice that clicking on the search button has a response delay of 400 ms.

• Long Tasks API – longtasks
  A 300ms JS task blocks the main thread during startup.

  This helps developers to address major issues and optimize the application.
