How hard is it to update Rails versions once deployed?
I've made an app with Rails 4 rc1 (release candidate one). There will be a newer version of Rails coming soon with the stable version of Rails 4 to follow soon after. I'm not sure if I should deploy now using rc1, and then update later, or should I wait until the stable version of Rails is released? On my local machine, it's dead simple to update Rails versions, is it much more difficult on a VPS?
