Introduction

React Native 0.81, officially released on 12th August 2025, is here to move mobile app development further with faster builds, leaner bundles, and an even smoother developer experience.

It has enhancements that signify stability and bug fixes. The new React Native version supports Android 16 and provides a greater experience for faster iOS builds through precompiled.

Let’s dive deeper into what’s new in React Native 0.81 and how it will be beneficial for your next project.

What’s New in React Native 0.81: Top Features & Updates

React Native 0.81 is a refinement-driven release that emphasizes better performance, a breaking change for Android mobile app developers, and significant alignment with modern mobile operating systems.

Here’s a detailed update and enhancement of React Native 0.81 you should know.

1. Android 16 Support

In this React Native new version, one of the significant highlights is the default to Android 16 (API level 36). It is for users who want to build Android applications with React Native 0.81. Google previously announced that applications can display content edge-to-edge, with no option to opt out in this version.

The React Native 0.81 version also introduces a new Gradle property called edgeToEdgeEnabled, which allows developers to extend edge-to-edge support to earlier Android versions beyond 16 for a consistent UI experience.

Moreover, the latest React Native version allows the predictive back gesture by default for Android 16. The BackHandler API continues to function in most cases. Still, apps that depend on custom native back handling, such as overriding onBackPressed(), may require manual migration or a temporary opt-out.

Developers should test their navigation flow carefully after upgrading into the React Native applications. Additionally, Google now expects applications to empower large screen devices regardless of size or orientation.

Even though an opt-out still exists, it is recommended for developers to update their responsive layouts before Android 17 enforces this requirement.

Another important update is related to Google Play compliance. From November 1, 2025, all app submissions must meet the 16 KB page size requirement for native binaries. React Native has already complied with this standard, but developers must ensure that any custom native code or third-party libraries also meet the need so they can avoid issues with app updates or new submissions.

2. Experimental Precompiled iOS Builds

React Native 0.81 introduces a crucial improvement for iOS developers with the initiation of precompiled builds. This feature, developed in collaboration between Expo and Meta, can reduce compile times by up to 10x in projects where React Native is the main dependency.

It builds on the starting work introduced in React Native 0.80 and aims to make iOS development faster and more efficient. Although the feature is still experimental, developers can try it by enabling two environment variables before running pod install:

However, there are a few limitations which you should be aware of. At the moment, you cannot debug React Native’s internal code in precompiled builds, even debugging your own native code still works as expected.

In addition, precompiled builds are not yet supported in Xcode 26 Beta unless you manually disable the SWIFT_ENABLE_EXPLICIT_MODULES flag. These issues are being worked on and will be addressed in future updates.

3. SafeAreaView Deprecation

In React Native 0.81, the built-in component has been officially deprecated. This component, created for iOS, keeps content away from notches, rounded corners, and other screen cutouts. However, it does not operate well with Android’s edge-to-edge layouts and only provides limited customization.

Due to this restriction, various developers have already switched to alternatives, such as react-native-safe-area-context, which offer better flexibility and cross-platform support. With this release, you will now see warnings in DevTools if your app still uses .

The component will be removed entirely in a future version. It is strongly recommended to migrate to react-native-safe-area-context or another similar library to ensure a consistent and intuitive UI across both iOS and Android.

4. Community-maintained JavaScriptCore Support

Another update in the React Native new version is that the built-in JavaScript Core (JSC) engine is no longer part of the application. Rather than this engine, there is a separate package maintained by the community. If your project depends on JSC, you will need to install the package to ensure there has been a version upgrade to 0.81.

However, the change does not directly affect the apps that utilize Hermes, which remains the recommended JavaScript engine for React Native.

5. Advance Breaking Changes & System Requirements

Here’s the breaking changes and system requirements you need to be aware of before upgrading to React Native 0.81, so your app can run smoothly and take full advantage of the latest features.

• Node.js and Xcode Upgrade Requirements

React Native 0.81 now requires Node.js 20.19.4 or higher, which is the latest Maintenance LTS release. To work with this version, developers may need to upgrade Node.js in their local setup or CI environments. Similarly, for iOS projects, the minimum Xcode version has been bumped to 16.1, so upgrading Xcode is necessary to continue building iOS apps.

• Metro Bundler Configuration Fixes

The Metro bundler has been improved in this release. Metro now properly respects advanced configuration options in community CLI projects like resolveRequest and getModulesRunBeforeMainModule in the metro.config.js file.

These settings had no effect in earlier versions, so if you previously customized them, you may need to revisit or remove those configurations to keep your project working as expected.

• Improved Error Reporting in DevTools

Debugging is easier in React Native 0.81. DevTools now provides clearer reporting of uncaught JavaScript errors, including the original error message, stack trace, causes, and an “Owner Stack” that shows where component errors come from.

This makes it simpler to track down problems. However, if your app logs errors to a backend or third-party service, you may notice differences in error reports after upgrading and might need to update your logging logic.

• New Macro and CMake Function for Library Authors

React Native 0.81 comes up with a new macro called RN_SERIALIZABLE_STATE, designed to support serializable state for components in the New Architecture. In addition, a new CMake function called target_compile_reactnative_options has been added to simplify setup by automatically applying the required C++ flags.

Only advanced or custom libraries with their own CMakeLists.txt will need to make adjustments. Libraries already using codegen without custom CMake files will not be affected.

How to Upgrade Your App to React Native 0.81? Step-by-Step Guide

Upgrading your React Native app to the latest version requires careful planning to prevent code breakage. Follow these steps for a smooth transition:

Step 1: Check Your Development Environment

You have to make sure your Node.js version is 20.19.4 or higher. For iOS development, you need to cross-verify that Xcode 16.1 or above is installed.

Review that your development and CI environments meet these minimum requirements before proceeding.

Step 2: Update Project Dependencies

For the React Native new version, upgrade your React Native to version 0.81 using your package manager:

If your project uses JavaScriptCore (JSC), install the community-maintained JSC package, as the built-in engine has been removed in 0.81.

Update any other third-party libraries to their latest compatible versions.

Step 3: Review Breaking Changes

• Replace with react-native-safe-area-context for proper edge-to-edge support.
• Check the new edgeToEdgeEnabled Gradle property and test predictive back gestures.
• If your app uses Fabric components interacting with the C++ Text API, update references from TextAttribute.h to ParagraphAttribute.h.
• Verify your app works with new Node.js, Xcode, and Metro configurations.

Step 4: Test Your App Thoroughly

To ensure the version update is smooth, you must run your app on multiple Android and iOS devices, including large screens and foldables.

Confirm back navigation, edge-to-edge layouts, and adaptive UI behave correctly. Check React Native DevTools for warnings or errors and update logging or code if needed.

Step 5: Optimize Build Performance

For iOS application, you need to enable precompiled builds to reduce compile times significantly:

Also, you must ensure that complex libraries with C++ code include the RN_SERIALIZABLE_STATE macro using target_compile_reactnative_options in your CMakeLists.txt.

Step 6: Finalize and Deploy

After testing and adjustments, rebuild your app in your development and CI/CD environments.

Deploy your upgraded app to stores, ensuring compliance with Google Play 16 KB page size requirements and iOS build standards.
