As old as this compatibility chart looks, it is still valid for 2.4.x and 2.6.x:

Basically, the network protocol has not changed since 2.0.

If you run into problems with a given driver, it is sometimes possible
to mix and match versions on the same machine (e.g. driver vs. upsd)
but in many cases, it's easier to just upgrade all of each machine's
copy of NUT at the same time (through a package manager, or by
installing to a separate location).
