The Oxygen team released today Oxygen 3.2 Alpha 1 and OxyPowerPack is fully compatible. The use of alpha/beta versions is not recommended on production sites though.
For the techies: The new Pro Menu included in Oxygen 3.2 Alpha 1 is the very first official component developed using Oxygen's undocumented API, the same API that OxyPowerPack uses for the CountDown Timer and the other elements.
So, now we can say that we are using the, still undocumented, but official Oxygen API.
