Status: Upgradable for Whonix GW & WS 17

I’ve looked around but can’t find anything related to this issue, so I apologize ahead of time if I’ve missed something.

But In the Qubes Template Manager, scrolling all the way down I can see that I can ‘upgrade’ the Whonix GW & WS for ‘qubes-templates-community.’

Apparently what I have is the GW & WS for ‘qubes-templates-community-testing.’ I assume this is a less stable version? To be honest, I didn’t know I had this version. I upgraded in the past when this option was available, but only because reading this forum at the time had convinced me to do so (I don’t remember why).

Anyway, is it recommended that I move to the non-testing version, and if so, will that completely change my respective templates to brand new installs?
