Hi there,

apparently, this repository is still on Ruby 2.

Coming from https://www.ruby-lang.org/en/downloads/releases/, I think it is safe to assume Ruby 2 is a thing of the past, and the repository should be upgraded to work with recent versions of Ruby 3? wdyt, @hammerhead?

With kind regards,
Andreas.

NB: This may also help to make GH-26 conclude without needing to bring in old Bundler releases still working on Ruby 2 in one way or another.
