I considered tagging it for stable, but I wanted it to get a bit of
testing first, it's a reasonably big patch.
I think we're reasonably confident it doesn't introduce any new bugs,
but more testing time is always good.
So I guess I'd be inclined to wait another week or so before requesting
a stable backport?
cheers
