I see that one of the proposals was a system like Ubuntu’s releases with . of release (To be honest that’s the first time I have heard that is what these numbers mean) with the main drawback being that people don’t understand that the part after the dot is still part part of the version number.
What I find interesting is that I didn’t notice a suggestion to use something similar to Windows 10’s feature updates release version number. For example, GNOME version 1903 (which would be GNOME 3.32). Would be a bit harder to misname compared to GNOME 19.03 for those users who might ignore the minor number. It would be a way bigger number though, and not much better than simply having a GNOME 2019.03 .
