Hi. One of my package (printrun) has this:
# AppData is CC0
License: GPLv3+ and CC0
Since the last time I've touched it, the license of AppStream metadata
files has changed  to FSFAP .
What should I use in the License tag? I didn't find the license at our
list at . Or is it just considered part of GPL, so I keep just that?
Do I need to announce this change (that IMHO changes no meaning what so
ever) on devel mailing list?
