We’ve had another round of important updates this month, including WordPress 4.8.3 to 4.9.0 early in the month, followed by 4.9.0 => 4.9.1 on the 29th. You may not see that one in your monthly report from us, as WordPress automatically updates the “dot” releases (those taking you from #.#.X to #.#.Y).
Sometimes the automatic updates get it done before we do!
