Yeah, there are various incentives and things that could potentially be used to get people to upgrade. I personally think giving less rewards to older versions might be useful, but I’m not sure everyone agrees.
Anyway, we can still reproduce some of the errors in the internal staging setup, so the first thing is to get the rate of those down to zero, or almost zero, as much as possible. Then when we can take that release out to the public, perhaps we can address some kind of strategy for upgrading incentives.
