Microsoft just released the UR 3 for System Center 2016 but as many if you have noticed there is no update for DPM 2016 within this release.
The reason is that there is no fixes made from the DPM team yet that can be released. This doesn’t mean that they have given up, got that question via email from a concerned user. Features and fixes will be released within the UR 4 release.
