react-native 0.64.0-rc.4

on Node.js NPM

THIS IS A RELEASE CANDIDATE: this means it's not stable yet, so proceed with care.

Please only upgrade or create new apps with 0.64.0-rc.4 if you'd like to help us test this before the stable release - which would be super useful 🤗

To test it, run:

npx react-native init RN064 --version 0.64.0-rc.4

We're working on the changelog right now and will update this release as soon as the draft is ready. Meanwhile, you may want to look at the most important changes that we have decided to highlight:

• Inline requires enabled by default
• New profile-hermes CLI command for converting Hermes tracing profile to Chrome format
• Hermes with Proxy support (will now support react-native-firebase, mobx)
• React 17
• Minimum supported Node version changed to 12
• Remove support of Android API levels 16 through 20. The new minSDK version will be 21+ moving forward
• Use of Xcode 12 is recommended to ensure no errors on iOS
