Apple released the 10.13.2 update to High Sierra this morning. I have installed it with no problems. I am currently testing my mission critical Apps, but as far as I can tell all is well, YMMV. As far as I am concerned, do the update. By the way, I checked for a Combo Updater, but there is none, at least not yet.
PS – They did finally release a Combo Updater. That is the best way to upgrade.
