To cut a release branch and check that everything works, you'll need Mac OS with the [Android dev environment set up](https://github.com/facebook/react-native/blob/master/ReactAndroid/README.md).
Run:
cd react-native
./scripts/release.sh 0.19 # Replace 0.19 with the version you're cutting the branch for :)
To go through all the commits that went into a release, one way is to use the github compare view: https://github.com/facebook/react-native/compare/0.18-stable...0.19-stable
Skip this for now, ping @mkonicek on messenger and he'll handle it. Docs [here](https://github.com/facebook/react-native/blob/master/Releases-publish.md).
IMPORTANT: `npm publish` will automatically set the latest tag. **When doing an RC release**, run `npm publish --tag next` - this way people need to opt in to get the RC release.
