Releasing

1. Update CHANGELOG.md.

2. Set versions:

   export RELEASE_VERSION=X.Y.Z
   export NEXT_VERSION=X.Y.Z-SNAPSHOT
   

3. Update versions, tag the release, and prepare for the next release.

   sed -i "" \
     "s/VERSION_NAME=.*/VERSION_NAME=$RELEASE_VERSION/g" \
     gradle.properties
   sed -i "" \
     "s/\"com.squareup.okio:\([^\:]*\):[^\"]*\"/\"com.squareup.okio:\1:$RELEASE_VERSION\"/g" \
     `find . -name "index.md"`
   
   git commit -am "Prepare for release $RELEASE_VERSION."
   git tag -a parent-$RELEASE_VERSION -m "Version $RELEASE_VERSION"
   
   sed -i "" \
     "s/VERSION_NAME=.*/VERSION_NAME=$NEXT_VERSION/g" \
     gradle.properties
   git commit -am "Prepare next development version."
   
   git push && git push --tags
   

4. Wait for GitHub Actions to build and promote the release.
