If bundle update for your Rails projects is a risky a frustrating process, try bundleup instead! I wrote bundleup to use the same Bundler commands behind the scenes, but added some nice enhancements. My favorite feature is how it color-codes the gems that will be upgraded according to semver, so you can immediately spot the minor (yellow) and major (red) version changes that might cause your app to break. Install it with gem install bundleup and check out the documentation on GitHub!
