Do newsstand apps require push notifications?

If I submit a newstand app that does not use push notifications, but instead queries my server for new content each time the user launches the app will apple reject my app? I.e. Do users expect push on all newsstand apps?

Thanks

Aroth has answered the question correctly but I want to add few important points to keep in mind for Newsstand apps based on my personal experience.

1. Apple will reject any Newsstand app without subscription in it. In case all your content is free still you have to create a Free subscription.
2. The content must be a magazine/newspaper/newsletter.No catalog etc in Newsstand.
3. The new content must come with frequency of at most a quater.

To answer this question

Do users expect push on all newsstand apps?

YES they will, because it is one of the most important functionality of NS apps and is assumed by default. Every single NS app in App Store has it.
