That’s it; that’s the extent of the updates. It has the same display size as the iPhone 5, the same camera that was in the iPad Air 2, and comes in the same colours as it has for years.
My first assumption was that this was an easy update so that iOS 13 could phase out support for A8-equipped devices. But I’m not so sure about that, given that the iPad Mini and iPod Touch models that were shipping just a few months ago both used the A8. Mind you, if those products were updated more frequently, this wouldn’t be an issue.
