Well, originally I planned to release v0.5 several months ago. And then 
breaking backwards compatibility wouldn't be an issue. But that's not 
where we are now, so I'll go for the intermediate solution outlined

But that will have to wait one more week, because I'm leaving tonight 
for a diving trip.
