Does anyone have favourite examples of software versioning schemes?

I may or may not be thinking about changing CryptPad's versioning system and I'm looking for alternatives. I like Ubuntu's date-versions (e.g. 20.04, 21.10) but we're on a different scale.

Also there's so much to take into account: our workload, incentives to ship features, 3rd party admins who apply updates, marketing of new features, etc

HMU if you have some examples (or own work) that you like!
