@ericmathison thanks for the pointer! fixed it. may i ask how you found this gist? just curious - i didn't expect anyone to find it and it doesn't seem very google-able.

This was my exact search: https://duckduckgo.com/?q=show+release+dates+in+gemfile

You are the first hit!

thats nice! maybe i should use the search engine that flatters me most 😁

my gist does not seem to be on google at all, but if anyone ends up here, my googling turned up this other gist that does the same, but is a bit more feature rich: https://gist.github.com/ixti/3680c400850e8fefe52ceeb94dac8b03
