ATTENTION: PLEASE REFRAIN FROM UPGRADING TO 7.0.16 FOR NOW. THIS RELEASE HAS AN
ISSUE WHICH MIGHT CAUSE HOST OS CRASH WHEN VM IS CONFIGURED TO USE BRIDGED OR
HOST-ONLY NETWORKING. WE WILL SEND AN ANNOUNCEMENT TO MAILING LISTS WHEN FIX
WILL BE AVAILABLE FOR DOWNLOAD.

leading to possible host crashes when high amount of traffic is generated
