Where is macOS Sierra 10.12.2?

This evening, around 1800 UTC on 12 December, Apple has released updates to bring iOS to version 10.2, watchOS to 3.1.1, and tvOS to 10.1. It has also released Xcode 8.2, with support for those and macOS Sierra 10.12.2.

But, for the moment, that 10.12.2 update has not been released.

It should show up any day now. I hope that its delay is to ensure that it fixes the vulnerability in SIP which was reported by Patrick Wardle of Objective-See, and some of the other important bugs in 10.12.1.
