Gluster users - Apr 2016 - What is the corresponding op-version for a glusterfs release?

After upgrading my cluster from 3.7.5 to 3.7.9 I got the following error when I
tried to enable quotas:

"quota command failed : Volume quota failed. The cluster is operating at
version 30702. Quota command enable is unavailable in this version."

After a brief search, I discovered the following solution for RHGS:
https://access.redhat.com/solutions/2050753 It suggests updating the op-version
of the cluster after the upgrade. There isn't any evidence of this procedure
in the community documentation (except for in this mailing list).

Unfortunately, nor 30709 or 30708 are valid op-version so I moved to 30707:

[root at s20 ~]# cat /var/lib/glusterd/glusterd.info
UUID=46ec7bcf-adf0-4846-a830-3d8205e96e89
operating-version=30702

[root at s20 ~]# gluster volume set all cluster.op-version 30709
volume set: failed: Required op_version (30709) is not supported

[root at s20 ~]# gluster volume set all cluster.op-version 30708
volume set: failed: Required op_version (30708) is not supported

[root at s20 ~]# gluster volume set all cluster.op-version 30707
volume set: success

[root at s20 ~]# cat /var/lib/glusterd/glusterd.info
UUID=46ec7bcf-adf0-4846-a830-3d8205e96e89
operating-version=30707

What is the corresponding op-version for a glusterfs release? RHGS has the
following solution that I found really useful, matching releases to the
suggested op-version: https://access.redhat.com/solutions/543123 Where do I can
find such information for the community version of glusterfs?

Thank you very much for your help.

Although the op-version numbering is aligned with the release versions
but that doesn't go as a strict rule. If any new volume tunable option
is introduced between the release then the op-version is bumped up.
Between 3.7.7 and 3.7.9 releases there were no new options introduced
and hence the op-version goes as 30707 for 3.7.9 release.

I do think that we should add a mandatory section about the op-version
number in every release note. I'll initiate a mail about that to let all
the release maintainers/managers know about it.

Thanks,
