[ovirt-users] Changes between Node NG 4.4.3 and 4.4.4

Hi, I have a node 4.4.3 install and it works perfectly for PCI passthrough. After I upgraded to Node NG 4.4.4 the PCI passthrough leads to server resets. There are no logs in the kernel messages just before reset apart from vfio-pci enabling the device. So, I assume there is some change related to the kernel or vfio-pci driver in the newer 4.4.4 version. How / Where can I see the differences between Node NG releases? Thanks, Shantur
