What’s new in React Native 0.64

React Native 0.64, released in March 2021, introduces several enhancements, particularly for iOS developers, with the integration of the Hermes JavaScript engine now being available on iOS, promising improved app performance through reduced memory usage and faster interaction times. This update also includes support for viewing Hermes traces in Chrome DevTools, proxy support, and inline requires enabled by default, which accelerates app startup by deferring JavaScript module execution until needed. React 17, included as a dependency, is identified as a "stepping stone" release facilitating safer embedding of React trees across different versions and integrating React with other frameworks more smoothly. Additionally, React Native 0.64 has updated its system requirements, such as dropping support for older Android API levels and raising minimum Node.js support. The update is seen as a result of contributions from over 100 global developers and is expected to continue evolving with community feedback.
