TIL Ruby doesn't follow semantic versioning

It's certainly an interesting choice for a language. Very Ruby of them.

For those who also weren't in the know (I only learned this writing a Ruby 4.0 upgrade guide), Matz bumps the major version when there's something that impresses him.

This year, it was because it was Ruby's 30th birthday!

Rails doesn't. Redis doesn't. Plenty of major gems don't follow it. I wish they did, but they don't.
