Previously it was not possible to upgrade RHVH to version 4.4.8 when custom VDSM hooks were installed on RHVH. This was caused by the VDSM hooks dependency on the concrete version of VDSM. The current release allows users to maintain the VDSM dependency manually. In other words, if you want to upgrade from VDSM X.Y.Z to version A.B.C, you must upgrade all VDSM hooks to the same A.B.C version. (BZ#2004469)
