bundleup 2.0.0

Use `bundleup` whenever you want to update the locked Gemfile dependencies of a Ruby project. It shows exactly what gems will be updated with color output that calls attention to significant semver changes. Bundleup will also let you know when a version "pin" in your Gemfile is preventing an update. Bundleup is a standalone tool that leverages standard Bundler output and does not patch code or use Bundler internals.
