The Virtualmin News forum. When Webmin.com mentions Virtualmin, it is about the virtual-server Webmin module, which is the most important, but not only, module in a Virtualmin system.
Because the 7.0 virtual-server module has been tagged and released on Webmin.com (though we had some problems with the new Webmin download server, so the module wasn’t even available via those links). But, Virtualmin is a whole pile of packages and an installer…virtual-server module is just one of the pieces.
Webmin.com is not “unofficial”, it’s just talking about something different. Webmin.com is years overdue for an overhaul, but we just don’t have a lot of time for it. If you only use Virtualmin, you can only read the news forum here at forum.virtualmin.com, and have all the information you need. We post about every Webmin/Usermin update that rolls into our repos (and you should not be using the webmin.com repos for a Virtualmin system), as well as all virtual-server and other major module and installer updates.
Virtualmin 7 is a new version of the installer, new repositories, new distro/version support, and new sets of dependencies. virtual-server module is actually a tiny part of what makes a new major major version of the whole system.
