Is there a difference between libappstream version and the standard version

[tintou]

The documentation stands that it is currently version 0.9
Does it mean that there is a difference between this repository release and the specification?

[ximion]

No, the major.minor version of this repository is the specification release, and the C library should implement the respective version fully. What you found is probably either a string-replace oversight, or we thought we would switch to 1.0 sooner back then...
It's corrected now, thanks for noticing!
