We support non retina devices, which are stuck on iOS 6. When this came out we weren't sure whether it applied to that too, so stuck with 50. We'd already been keeping it under 50 for 6 months by then so we had all the infrastructure set up, its mostly automated.

Haven't looked at it since iOS 7 launch though, do you know if it was iOS 6 too?

Just checked with a couple folks here, the limit is for the iTunes store, and therefore was also raised for iOS 6 (we assume older versions as well, but don't support them either).

Interesting, thanks. Maybe next time we update, I'll try to convince everyone to panic-delete a little less :)
