Could this be because of Apple's discontinuation of iAd? After June 30th, developers will no longer have access to this feature (it's been a present feature for Apple apps since 2010).
There's also a requirement as of June 1st that requires all apps to use IPv6. I'm not a developer but given that IPv4 has been around since forever, could the adoption of the new IPv6 be causing a lot of developers to not get their software accepted by the Apple monitors?
Normally we get at least a half dozen releases each day but over the past week we've seen maybe three or four releases. Is this just a weird funk?
