[ovirt-users] Question about upgrading ovirt 3.5.3 to 3.5.4

Hi. I have a system consisting of an engine + several hosts running 3.5.3, and I want to upgrade everything to 3.5.4. According to the release notes, all I should do is: I did this with engine, and it seemed to upgrade okay. I'm puzzled whether this applies to the hosts as well? The release notes aren't clear to me in that respect. Thanks for any assistance! Jason.
