Skins in beta 12 frodo

RPI user.

I was looking to get quartz but no skins appear in the add on list, just confluence and transparency.

I figure this is because there are no skins yet in the frodo repo but when I go to the frodo wiki it shows a handful of skins including quartz.

I'm using openelec with xbmc beta 2.

Is it a simple matter of upgrading or should I expect these options off the table until stable release or something else?
