System Center 2016 Update Rollup 3
UR 3 for System Center 2016 have started to surface now and in the windows Catalog I have found VMM and SCOM 2016 UR3 packages. There are quite a few fixes and if you have a dev or stage environment you should start to evaluate this new rollup!
SCSM 2016 UR3 could be found in the download center at this link
There are no UR3 for DPM,Orch, SMA and SPF as according to this page: https://support.microsoft.com/en-ph/help/4020906/update-rollup-3-for-system-center-2016
