“ZeroVer is satire, please do not use it”
Less has my favorite version numbering system. Sequential.
Latest stable release: Version 598
Perfect for things like Ubuntu, pytz, and ca-certificates.
Less for something like a library who’s API could change and break your implementation.
Especially, like, what if you release a bugfix for a significantly old version? Do you give it an up-to-date number? Do you not give it a number at all?
(Also I see a 581.2 on that page.)
