:In regards to existing hammer instalations that run the initial HAMMER
:release, do I have to upgrade to HAMMER WIP?

It isn't necessary for the pruning feature.
If it is still calling it WIP then you have either an old kernel
or an old hammer binary. Do not upgrade to the WIP version, it
will break the filesystem (that's why there are so many warnings
if you try to do it).
With a recent kernel version 2 will be marked as 'NORM'. It is a
different implementation then what was in WIP. If version is is
marked as normal then it is safe to upgrade to it and the utility
won't spew dire warnings at you when you do. But note that
older kernels will not be able to read that filesystem. The upgrade
will apply only to newly created directories.
