hi, do you have tips where can i find information about new features in cluster levels? i found only https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/htm... there is only information "there are new features" hard way i tried check https://www.ovirt.org/release/4.5.0/ and found https://bugzilla.redhat.com/show_bug.cgi?id=2021545 - Detecting if scratch disks can be extended automatically - Detecting if host support disk format conversion - Maybe for using qcow2 format by default to enable incremental backup by https://bugzilla.redhat.com/show_bug.cgi?id=2033185 - e1000e is there some "central" place ?
