XenForo 2.2 is coming soon, it's bringing many new features such as a PWA app for OG etc. It also comes with the drawback of more costs to update themes/some addons. It'll also remove access to some older browsers which'll suck but these shouldn't be used as their security sucks.
With the costs already looming we decided to improve OG's look with a new fancy theme that gives OG a more gamer feel. This has cost us only slightly more than it would have cost to renew the current theme and runs alot nicer.
You can beta test it here: Linky. (Please note only dark is live, light will come once issues are ironed out.)
If the current theme breaks on update we will end of life it, but we'll make something looking similar based on the default free theme so don't fret!
