Versioning Numbers, make them meaningful

Reading Time: 1 minute

The version number itself, and more generally the way you manage it, is most of the time underestimated, because it’s considered something trivial.
It is used to give a chronological order to the software releases and it conveys the useful information about the state and the impact of the release.

I can think only of two major way to assign a version number:


Obviously there are several ways of customising those to your own needs, and you can find everywhere different, non-standard, version numbers every day being used.

But, personally, I prefer the following structure and I’d recommend it to everyone:


The rules are quite straight-forward:

  • increase MAJOR when releasing something that is NOT backward compatible
  • increase MINOR when releasing something that is backward compatible
  • increase PATCH when releasing a bug fix (obvs backward compatible)
  • the stability follows this order:
    1. alpha
    2. beta
    3. dev
    4. rc

Usually I never bother to use alpha and betabecause they are so unstable and so frequently updated that it’s not worth the time to create a tag and release it, I’d rather release a dev one.

I also found out that there is even a manifesto for the versioning scheme I’m using and promoting.

However, this is not preventing you anyhow to assign to your release a codename.

This could be a solution to avoid problems when deciding which version to use, recognising at first glance if the release is stable or not, and especially be aware whether it’s backward-compatible.
Still, do not ever trust blindly an external dependency.
