I don't think that it is normally a problem. It's very unusual for there to be such a gap between full releases. If anything, in the past it has taken a little while for the cli version to catch up. However it seems that the owner of this project does not have enough hours in the day at the moment and so a 2.10.x desktop version has not yet been classed as a full release.
EDIT:
As I was typing this a new post appeared so it looks like a v2.10.x is now in the process of being classed as a full release.
