Monotron is monotonic

Monotron is a monotonically incrementing⁠ value generation service. It generates values that are always one larger than the last value it generated.

Cool, why?

This is intended to be useful for versioning releases of software via CI/CD pipelines. For a given key, the system maintains a series of values where each successive value is one larger than the previous. You can use it to generate the next sequential version number for your release and attach some metadata to that version.
