Support for specific version and/or --patch --minor flags

Cool gem!! I love it.

bundle outdated includes flags to restrict its output to only the next patch or minor release of a gem. It'd obviously take a bit more work to discover the gem version to grab, rather than just the newest one, but it's a feature I think would be cool to add, fwiw.

Thanks! Hope you find it useful.

Both of these features would be good to have, I use those flags with outdated. The main difference is outdated typically reports on multiple gems, but I think the semantics are close enough.
