[AppStream] AppStream 0.9.4 released!

[Matthias Klumpp]

Hi!
Notable changes in this release is switching the default path for
metainfo/appdata files to /usr/share/metainfo, which is a less generic
and more precise name (which makes it clear that you can use metainfo
files to add metadata for any software component, not only "apps").
The previous path will likely stay supported for eternity.

Aside from this change, the release contains many changes needed at
Ubuntu to make GNOME Software work (and tools like KDE Discover not
break), as well as some future-proofing of DEP-11.

As always, tarballs are available here:

Cheers,
    Matthias
