The last step in a capistrano deployment is symlink
ing the working release directory from /app/releases/[TIMESTAMP]
=> /app/current
. If this symlink has not been updated, but you see a release in the releases directory, something has failed along the way.
If you paste the entire logs of your deploy, I can help you find what has failed. You will need to solve the root cause of this failure in order to see a successful, complete deploy.
