React Native: v0.62.0-rc.4 Release

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

Please only upgrade or create new apps with 0.62.0-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 RN062 --version 0.62.0-rc.4

This version introduces the new LogBox experience behind a feature flag. To try it out, add the following to your index.js file:

require('react-native').unstable_enableLogBox()

This version also introduces Flipper integration and support for a new version of Hermes (0.4.0). For details and to report issues, see this issue.

This release will be quite massive (there are around 1200 commits of delta between this version and 0.61!) so we don't have the changelog ready yet (draft PR) - it will be fully ready for when we will publish 0.62.0.

You can participate in the conversation on the RC status this issue for updates, where you can post your bug reports and cherry-pick suggestions.
