I'm happy to announce that we just released push-button upgrades for people hosting their masternodes with Node40. You can now control when you update your masternodes with a couple of clicks. There is a blog post explaining the process for upgrading without a protocol change. I'll be doing another post later that walks through upgrades with a protocol change. Either way, the system will let you know what type of upgrade will occur.
