Were in the last beta, so only a couple of weeks at the most.
That's reading between the lines.
As we find more bugs they have to be tested again.
P.s i converted from 6.5 --->> 7.0
On my live forum i'm still on 7.0.2b
And my test forum 7.1.5b
I would wait mate.
Or do a convert and use the New Database as your testing forum
