The package providing gpg capability is qca-gnupg, so that's the one to watch.

New abstractions, ported code, deferring optimizations to later releases.  
Yes, this can bring weird results. :)

It's not that existing keys change (although they could, and Psi would track 
it), but rather that new ids might get added.  Monitoring the keyrings saves 
us from needing some sort of manual "refresh" button.
