Ruby 4 isn’t only about experimental features.
It also brings a set of “quiet improvements” that directly impact everyday code:
Set as a core class, Array#rfind, improved inspect control, multiline logical operators, high-precision math functions, and subtle performance refinements.Small changes — real practical benefits.

Apparently Ruby 4.0 removed pstore from the stdlib's set of default gems. PStore is used by YAML::Store, which is still part of the yaml gem. Maybe yaml-store should be split out as well? Kind of weird to have something still in stdlib that requires non-stdlib gems.

🎉 Ruby 4.0.0 is here, folks, because clearly what we all needed was yet another version of a #language that's already as popular as a mime at a podcast convention. 🙄 Now available in every language you never asked for. 🌍🚀

🚀🎉 Ruby 4.0.0 Preview2 is here to save us from the grueling monotony of... Unicode updates! 😴 Nil is still having an existential crisis, refusing to call methods like it just doesn't care. Maybe next version, they'll teach it to make coffee. ☕️🤔
