App Version Check

Seems like a nice idea. Not sure how'd that work as a built-in, though. Off the top of my head, I can't think of a good way to make this generic. Maybe a specific GitRevision check, could work. Or even one that can inspect a handful of common VCSs.

Yeah thats not a bad idea. I was thinking we could use a generic version file or something.

Capistrano 3 now puts the current release version in a REVISION file in the app root. That seems a reasonable default location to read, with either the (relative) file path a configuration option, or maybe a configurable block to execute which would output the revision (e.g., in our Unicorn configuration, we parse the revision into an environment variable visible to the app).

I like using the REVISION file. using an ENV variable is fine too. We could try those two things and then give up. a user could set it themselves in an initializer.
