[ovirt-users] Gluster version upgrades

Is the gluster version on an oVirt host tied to the oVirt version, or would it be safe to upgrade to newer versions of gluster? I have noticed gluster is often updated to new major versions on oVirt point release upgrades. We have some compute+storage hosts on 4.3.6 which can't be upgraded easily at the moment, but we are having some gluster issues that appear to be due to bugs that I wonder if upgrading might help. Would an in-place upgrade of gluster be a bad idea without also updating oVirt?
