@mtgranito Welcome to the Rockstor community forum.
Re:
Yes, our current downloadable installers have pre-installed 5.0.15-0 which is at Stable Release Candidate 10:
15.6, as per the recommendation on the Downloads page. Tumbleweed is hard to track as it changes so often and we offer it for more advanced users and to see where we are heading as it were. I.e. folks can, via the Tumbleweed based installer, assess what we need to accommodate and how we are doing for future versions as it were.
Also note that subscribing to Stable, on an openSUSE Leap 15.6 based installer, even thought we are pre 5.1.. Stable release, is find. It just means your system will be held at it’s current ‘rockstor’ rpm version until we do publish our next Stable rpm. We got folks onto late testing (Release Candidate) in our more recent installers given this last testing phase has been a rather long one. This way we ensured new installs where based on near modern Stable (RC), rather than older Stable, as they were. Plus we had a lot of work to do re updating and testing the installers also. But the vast majority of this work has now been finished.
Hope that helps.
