Can someone describe to me how these jQuery releases make their way into Rails 3.1 land? Does the maintainer of https://github.com/rails/jquery-rails do an update and then it's up to us Rails users to execute a "bundle update"?
My recommendation would be to maintain dependency versions yourself, i.e. download the version of jQuery you want to use and //= require jquery in application.js - then grab a new version of jQuery whenever you want it updated
