Hello,
I'm just noticing changes in web page for release notes of oVirt 4.0.5: 
http://www.ovirt.org/release/4.0.5/

There are now several links to the corresponding official RHEV documents.
I think this is good, especially if they remains not so far each other. 

I just noticed 2 things:

1) the command engine-upgrade-check
That I didn't know and seems to work quite good in oVirt 4.0.4
It gives me

[root@ractorshe ~]# yum clean all
Loaded plugins: fastestmirror, versionlock
Repository virtio-win-stable is listed more than once in the configuration
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast

Upgrade available


2) Command to upgrade the engine
In oVirt page we have
yum update "ovirt-engine-setup*"

In RHEV we have the command without the star
yum update ovirt-engine-setup

If I remember correctly the star was important in the past.... 
Any comments on this difference? Documentation error or different functionalities or dependency chain changed so that now it is not necessary the star also in oVirt?

Thanks,
Gianluca
