- Make the commit on the master branch and pick in to stable
----------
## Cherry Pick
1. Check out a new 'stable' branch from 'master'
1. Change back to 'master'
1. Edit '`cherry_pick.rb`' and commit the changes.
1. Check commit log to get the commit SHA
1. Check out the 'stable' branch
1. Cherry pick the commit using the SHA obtained earlier
----------
