React Native Windows 0.81 Enables New Architecture by Default
Microsoft aligns with React Native 0.81.5, deprecating Paper architecture as DevTools debugger support arrives.
Microsoft has released React Native Windows 0.81.0, aligned with React Native 0.81.5. This release marks a significant milestone as the New Architecture is now enabled by default, with the legacy Paper architecture facing deprecation.
New Architecture Default
Starting with React Native Windows 0.80 and continuing in 0.81, the New Architecture is enabled by default. Microsoft strongly recommends migrating to take advantage of improved performance, long-term support, and modern capabilities. Paper architecture will not be supported from React Native Windows v0.82.
DevTools Support
React Native DevTools—the modern Chrome DevTools-based debugger—is now supported in React Native Windows v0.81. This brings feature parity with iOS and Android debugging experiences, allowing Windows developers to use the same familiar tooling.
Architectural Enhancements
The release includes major architectural improvements, enhanced performance, improved developer tooling experience with Hermes Debugger integration, and numerous reliability fixes. These changes lay the groundwork for continued Windows-specific optimizations.
Deprecation Timeline
Meta is officially deprecating and removing the old architecture starting with React Native 0.82. Consequently, React Native Windows old architecture (Paper) will be deprecated in react-native-windows@0.82, with the codebase deleted along with all legacy support.
