@WyldanimalYou said something similar 514 - which then turned out to be a beta.
In my opinion
If 516 is not a beta then there really ought to have been an offical announcement of that fact by Totem. Leaving it as an almost invisible option for existing users unless you go looking for it is silly.
As far as I can remember Totem did very visibly make an announcemeny for all previous official releases.
The Team needs to get feedback from New Members
The team also needs to get feedback from old users, including those that avoid using beta versions of software. In my opinion feedback from existing users is rather more important than feedback from new users who have nothing to directly compare the new version with.
It is still not entirely clear to me whether 516 is a beta or not (though I lean toward "not").
