Client Version

If you're building an API, it can be really helpful to be able to force your clients to upgrade to the latest version. This is Rack middleware that simply adds a Client-Version header to every response with the value of the CLIENT_VERSION environment variable. Your clients can use it to determine whether they should force the user to upgrade to the latest version.

Installation

You know the drill:

# Gemfile
gem 'client_version'

$ bundle install

Configuration

If you're using Rails, you're all set; we've hooked into your middleware stack for you. Otherwise just add ClientVersion to your middleware stack.
