Wazo 20.01 or 19.17

I am just learning and planning to install Wazo 19.17 but now I see that Wazo 20.01 is being discussed.
Is Wazo 20.01 what I should be installing in a production environment? Or is Wazo 19.17 still the stable version and 19.17 is what I should be installing for a production version.

We release each 3 weeks a new version. The 20.02 is planned this next monday.

When I see a version number change (before the decimal) I think it means a significant software revision.

Is there a big difference between 19.17 and 20.01/02? I looked at the changelog and am not sure I understand all the changes.

Or is 20.01/02 just a natural evolution of 19.17?

No wazo platform haven’t this versioning. 20 is the year and 01 is our iteration number. https://wazo-platform.org/blog/sprint-review-2001

Thank you; I was not following the nomenclature properly. I now get it.

How do I ask the system what version is currently running?

I cannot see a place in the Web UI and I have not found a command-line to do it.

What I have found is that by running

cat /usr/share/wazo/WAZO-VERSION

I can see the version, but I am not sure if that is the correct or recommended method.

wazo-upgrade say the current version you have and the next version you could upgrade.

Got it, thank you

I wanted to know what version I was at before running wazzo-upgrade so did not try that.

But of course, wazo-upgrade always gives me a choice to proceed or not, so this is the best way.
