I just got the following email from Apple regarding the free version of I Can Has Cheezburger:
Thank you for submitting your application update to the App Store. Unfortunately, the update to I Can Has Cheezburger 1.5.4 cannot be posted to the App Store because the Release Notes mention features that are only available in the Pro version of the application. It currently reads “Save to favorites is available for all items in the pro version.” instead of accurately describing this application’s update, which may lead to user confusion.
While your iTunes Connect Application State is displayed as Rejected, it is not necessary to upload a new binary. Once the necessary modifications are completed, please reply to this email and we will proceed with your application review.

I changed the description as requested, so hopefully it will be approved soon.
