Elon promised 8.1 starting in a few weeks - and also talked about features that will be in 8.01 before 8.1 comes out - so I'm thinking this slowdown you're seeing is an indication that we're about to see 8.01 rolling...
I'm starting to agree. Something is probably up -- there's been little to no updates for a while now. I suspect either this is gearing up for 8.1, or there will be yet another everyone-gets-it 8.0 update.
