React Native v0.64 was released in March 2nd week of 2021. Let us look at the features of React Native latest version.
New Features of React Native v0.64
Hermes support for iOS
To enable Hermes on iOS, set
true in your
Podfile and run
pod install. Hermes support on iOS is still early stage. This option is kept as an opt-in instead of default.
Default support for Inline Requires
Inline Requires is enabled by default for new applications to help people have fast React Native applications without extra configuration. Earlier this was a opt-in configuration in earlier versions.
React 17 does not include new developer-facing features or major breaking changes. For React Native applications, the main change is a new JSX transform enabling files to no longer need to import React to be able to use JSX.
Upgrading to the new transform is completely optional, but it has a few benefits:
- With the new transform, you can use JSX without importing React.
- Depending on your setup, its compiled output may slightly improve the bundle size.
Major Dependency Version Changes
Android API levels 16 through 20 support will be removed. The new min Android SDK version will be 21+ moving forward.
The new version of React Native also requires Xcode version 12. Minimum supported Node version is changed to 12.
React Native developers can make use of the new features of the latest version while creating new applications or upgrading their existing apps.
