Right. The release rpm in pub/yum-repo was for 3.6.6. The one in the 3.6 repos
was more up-to-date. Since both point at the same ovirt-3.6 repo on the ovirt
site, you got same release. There were some other minor changes in the release
rpm between 3.6.6 and 3.6.7, mostly related to gluster repos, as you can see
in [1]. Just in case, you can update your release rpm, then try 'yum update'
again (perhaps following 'yum clean all'), to see if there are actual updates
you missed due to the differences.

In any case, the rpm in yum-repo is now updated.

Indeed, now pushed a change [2], will hopefully be merged soon.

Explained above. That's unrelated to the double repos.

One you finished upgrading to 4.0, you can safely remove the 3.6 repo files:

# rm /etc/yum.repos.d/ovirt-3.6*
# yum remove ovirt-release36

But generally speaking, there is also no harm in keeping them.

OK too. Actually in reality you might have a few more such cases -
of packages you installed from 3.6, that 4.0 did not require to update,
but an update is available - so you should, but that's not strictly
neccessary - just like any other package for which an update is available -
E.g. ovirt-vmconsole etc.

This is an update from the centos virt sig repo. Again, like any other
package, better update - but up to you. ovirt-engine-websocket-proxy requires
at least 0.6.0, so should probably work even without updating it.

Best,
