I realized changes on ovirt web admin interface, improvements on icons and maybe new fields. some features in the engine do not require anything from hosts/cluster/DC, so you get them without upgrading the hosts/clusters/dc's. for features that require an upgraded host/cluster/dc, you will only get them when you upgrade them accordingly.

Re: [ovirt-users] compatibility relationship between datacenter, ovirt and cluster
you should look at the feature page. if you do not fully upgrade cpu/data center you simply continue to work with 3.3 features On 04/10/2014 08:50 PM, Tamer Lima wrote: Hi, yesterday my ovirt was 3.3 my datacenter and cluster (compatibility version) was aligned with ovirt 3.3 today my ovirt is now 3.4. and my datacenter and cluster (compatibility version) remains 3.3 (with the option enabled to change for 3.4) browsing the ovirt admin page I see 2 occurrences of ovirt version: datacenter tab = 3.3 cluster tab =3.3 I would like to understand what means all these versions, the same version for a lot of important things, and how my ovirt works/behaves using different versions. all my doubts together : What means datacenter in version 3.3(or lower version) when ovirt is 3.4 ? what means cluster in version 3.3 when ovirt is 3.4? what means change the compatibility version for datacenter? what means change the compatibility version for cluster? thanks ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- Dafna Ron ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Also I found release notes for 3.x, but not for 3.4 yet, at least from page http://www.ovirt.org/Documentation Can anyone add this link to it? http://www.ovirt.org/OVirt_3.4_Release_Notes I can do it, but I'm not a maintainer... and this is the main page... let me know if you wish me to do. You can also follow RHEV documents, tough its versions are not completely aligned with oVirt versions.
