I wondered what could be so important to push yet another update out after last one (update 2 was pushed to fix a serious metal regressions that caused severe flickering that was quite bad for epilepsy or other sensitive conditions).
So what was left for yet another update to fix?
The Panic in nvidiastartupweb if it loads on an unsupported OS version. By changing OS build number for sake of testing, it seems 221 now correctly passes control over to stock driver without exploding the whole system.
This means that if you are on 10.13.0, install this update now, so that when 10.13.1 comes out, you shouldn't have dick around with removing the old driver before updating. it should correctly handle things now, making the upgrade procedure go back to normal.
Of course, one should still always have good backups, and I hope anyone who got caught in reboot loop last time with pants down has learned from that
