Untz decided to resign from his position as the board's chairman due to a "happy personal event", which presumably is a child on the way with the statement, "a happy personal event that will take up a lot of his spare time in the months (and years!) to come."
Vincent Untz served as the openSUSE Board Chairman the past two years while now SUSE -- as the primary sponsor of openSUSE -- has selected Richard Brown to serve as the new chairman. The announcement was made on news.opensuse.org.
Vincent Untz has also made some parting comments on his blog. Congratulations to Vincent Untz and Richard Brown on their respective events.
