Is 64-bit a requirement for publishing to the iOS App Store? iOS developers recently received an email from Apple stating that 


  Starting February 1st, new apps and app updates submitted to the App
  Store must be built with XCode 4 and iOS 7 SDK


The email included a link about building apps for iOS 7.

One of the item on this page, is about 64-bit compilation.

So the question is, should I deduce that 64-bit is now a REQUIREMENT, or is it still a recommendation?
Apple just announced that starting 1. February 2015, apps have to support 64 bit. Source: https://developer.apple.com/news/?id=10202014a. So, it will then be a requirement.
