The sidebar is meant to call attention to apps that have been updated
recently, so at the very least, they should describe what is
new. "What's New" is also is a simple marker that means generally the
app is including other metadata like screenshots or localization.

I tried implementing the same rules as fdroidclient!805 (merged) /
fdroid-website!398 (merged), but my Liquid scripting skills are weak,
and Liquid scripting is weird.
