Major Enhancements

Hermes for iOS Support

An optimized JavaScript engine previously limited to Android now extends to iOS, improving startup performance and reducing memory consumption and app size.

Inline Requires as Default

Module execution is now deferred until needed rather than at startup, enhancing application performance without requiring manual configuration.

React 17 Integration

Developers can now use JSX without importing React, potentially reducing bundle sizes and simplifying code structure.

Dependency Updates

Minimum requirements shifted to:

  • Android SDK 21+
  • Xcode 12
  • Node 12

Discontinued support for older Android API levels (16-20).
