[AppStream] AppStream 0.14.2 released!

[Matthias Klumpp]

Hi!
This new AppStream release brings you quite a few bugfixes, but also
slower searches! Also, better search results more in line with what
users generally expect them to look like.
Even with these changes, search queries are still extremely fast.
I also by accident plugged a pretty big memory leak in the Qt
bindings, so KDE users will definitely want this release.

As usual, tarballs available here:

Cheers,
    Matthias
