Heads-up about AppStream 1.0 no longer honoring legacy metadata locations

[Nate Graham]

Hello folks!

Plasma 6 will require AppStream 1.0, which we just discovered no longer 
honors legacy metadata locations, including 
/usr/share/app-info/(xml|xmls) and /var/lib/app-info/(xml|xmls). If your 
distro is currently storing metadata in one of these locations, it needs 
to be moved to /usr/share/swcatalog/xml or /var/lib/swcatalog/xml. Icons 
also need to move.

If this migration is not performed, Discover in Plasma 6 will not be 
able to see any of your distro's apps.

See

for more information.
