Release checklist

Once you've started a release branch, immediately do the following:

Bump app version (use the bumpVersion.sh script)
Check the parameters URLs in the ServerConfig classes (debug, qa, release) are good (e.g. non-dev)
Update GRAMMAR-VERSIONS.md with the parameter grammar version used in the release you're about to do
Update CHANGELOG.md with this version's changes
Build, check everything still works
Run sign.sh <version-name> to create signed and zip-aligned APKs
Run deploy.sh <version-name> to deploy APKs to website
Upload APK(s) to the Play Store
