Hi Doug,
Not sure exactly what you mean with "moving" to the v4 client.
I remember that ROOT had to be updated to work correctly against the v4
build. If some changes had to be made to make ROOT source compatible
between v3 and v4, then I'm fairly sure that releases from these two
series are not binary compatible with each other.
Since we don't do the ROOT builds ourselves, but take then either from
the ROOT webpage, or from the LCG RPMs, we use whichever XRootD version
they compiled ROOT against. For LCG (and maybe even the ROOT builds put
on root.cern.ch) this is still v3.
Cheers,
Attila
