Ruby 2 stops receiving security updates at the end of March

[jadatkins]

Ruby 2 is reaching end-of-life and will no longer receive security updates after 31 March 2023. Most production Ruby code, therefore, must be running on Ruby 3 no later than 1st April onwards.

I've had a quick look and found the attached failures and errors when running the tests for fakeweb under Ruby 3.

For the software I care about today, I'll probably just break the dependency chain further up, so that we no longer depend on fakeweb, but I figured I might as well post this somewhere.
