Enhanced Performance

1. TurboModules and Fabric: React Native 0.74 continues to build on the advancements of TurboModules and the new Fabric renderer. These technologies aim to enhance performance by enabling faster JS-to-native calls and offering more efficient rendering. The migration to these systems is becoming more stable, providing a smoother development experience.

2. Improved Startup Time: Efforts have been made to reduce the startup time of React Native apps. This has been achieved through optimizations in the bundling process and improvements in the initialization of native modules, making your app feel snappier right from the launch.

New Features

1. New Architecture Updates: The new architecture is now more accessible with improved documentation and tools to help developers migrate their existing projects. This includes better support for Codegen, which automatically generates native code bindings, reducing boilerplate and potential errors.

2. Hermes Updates: Hermes, the lightweight JavaScript engine optimized for React Native, has received updates for better performance and stability. With improved support for ES6 features and enhanced garbage collection, apps using Hermes will benefit from faster execution and reduced memory footprint.
