Rocketbox support in 2.6

I notice that one of the updates in the latest version (2.6) is "NEW: Added Rocketbox support to Mail application template".
How does this affect an already existing setup (having used the Mail application template for a while now) with Rocketbox already installed. Would it be worth it to remove the setup from Espionage and then re-add it using the new updated template? Or, are the benefits already realized just through the upgrade.
Thanks,
Steve
