Verizon has pushed out the monthly update a week or two early this month. No complaints there. For the regular S7 that brings us to software version NRD90M.G930VVRU4BQK4. I was prompted to update during the overnight and I did so. No issues encountered. Just a bump in Security Patch level to December 1, 2017.
While not specifically noted in the update info this update does take care of a concerning vulnerability. The December 1 Security Patch resolves the newly publicized "Janus" vulnerability in Android. Google was notified of the issue back in July and released a patch to developers in November to be included in the December security updates.
