React Native Stability and the Road to 1.0#
According to Meta’s Ricardo, 2025 is positioned as the year of React Native stabilization. The release process is being improved, with a plan to ship 6 releases per year, once every two months — making upgrades easier and reducing bugs and breaking changes. React Native 1.0 is now within sight, with efforts around predictable releases, stable APIs, and fewer breaking changes laying the groundwork. On versioning, up to three versions back from the latest will be officially supported.
👀 React Native 1.0 is finally on the horizon Announced at React Universe Conf, they will share the plan to reach 1.0 soon! RN recently: - improved its release process (6x/year) - stabilized and clarified its public APIS - introduced workflows to catch breaking changes
Removal of the Legacy Architecture#
React Native 0.81 already recommends using the New Architecture, and version 0.83 — scheduled for release in December — is expected to remove the Legacy Architecture from the React Native core entirely.
React Native core team is planning to remove all code related to the old archicture on 0.83. Nice, this will result in smaller IPA/APK sizes. At least they will keep the interop layer around See RFC: github.com/react-native-commun…
Introducing Uniwind#
At React Universe Conf, Jacek — the author of React Native Unistyles — announced a brand-new library called Uniwind.
Thank you @callstackio for the amazing conference! Thank you @grabbou and @thymikee for the hospitality and the opportunity to speak at one of the largest RN conferences worldwide! It was a pleasure to speak at @reactuniverse_ and meet so many legends and amazing people.
UniWind is a library that brings a Tailwind CSS-like API to React Native.
Meet the 2nd gen Unistyles 🦄 engine: update any React Native style - Button color, Switch thumbColor, ScrollView contentContainerStyle, and more. No mapping. No wrapping. It just works with no re-renders.
It promises high performance, and while Tailwind-style libraries for React Native like NativeWind already exist, it’ll be interesting to see which one ends up dominating the space.
