Yes. Upgrade to version 5 is needed just to record the fact that
bytes_free field in layer2 freemap structure is now signed. It's been a
signed integer for at least three months now and the upgrade itself is
harmless. However you don't need to upgrade unless you have some spare
backups to try dedup code or you mix HAMMER filesystems created under
master and stable branches (if you upgrade to V5 and then try mounting
that upgraded filesystem from stable (2.8) branch, it will refuse to
mount.
