Hello,
Over the years there have been many proposals regarding the versioning
of CloudStack. The biggest hurdle has been the "4" as a prefix, which is
useless at the moment.
I've looked up many of the proposals and discussions (see below), but
none of them went anywhere, they silently died. I want this to change.
Ubuntu and Apple us a versioning system where they prefix with the year,
in 2026 this is "26" and next year it will be "27".
I don't think we need to follow years, I would support it, but the
basic number would be good enough to me
Proposal in the past where to drop the "4" and that would be 20 in the
4.20 era (2024!!) and this would now be "24" as we are approaching
version 4.24.
I think this would be the easiest change by making our next release "25"
and not 4.25 anymore, with one note: 25 is very close to (20)27 and it
might be better to jump from 25 to 27 as our next release will be in
2027 after we release 4.24.
Here lies my only concern. This will restrict us to at most one major
per year. I like our custom of late where we have a non-LTS in spring
and an LTS in autumn (around CCC)
If we address this . (i.e. allow for experimental features in some way
that will not harm more conservative users) I am 100% on board.
We could stick with it as-is, but only remove the "4". That's my main
concern, that prefix of the "4" has to be dropped and this has been
proposed many times.
Nothing else changes, the 4 just goes away. Completely happy with that.

We can go over many details, but in general I'd like to get consensus
and get things moving on this topic.
Any major objections before I start a VOTE? The VOTE would be that there
will be no 4.25 in 2027, but we will have version "27".
Thanks,
Wido
