New watch face coming today but apparently will work with current version of watchOS. So maybe something later today?
I just got this notification, too. The Watch App crashes when I open it, though.

That capital D is not the quality control increment (I’m sure someone, like @TimFL1 ,knows what it’s really called). The capital D is the minor build version number, meaning that this is the 4th minor version of iOS 15 (the earlier ones being 15.0, 15.1 and 15.2 ).

What you are thinking of is the lower case letter that appears at the end of a build number for a beta. Those represent how many times the build had to be compiled before QC allows it to be released. That’s why you theoretically want those to be letters earlier in the alphabet, as it means the build had to be compiled fewer times before meeting quality control standards.

As you will note, the lower case letter is omitted from the release candidate build number.

That article is actually wrong when it comes to the capital letters. These are the kernel version, which most of the time is tied to minor releases (in terms of being updated) but they can also lag between minor builds. If you take a look at the release history for beta builds you can find several outliers where e.g. x.0 and x.1 are both A letters and you can also directly verify that the kernel version is the same for both releases.

But the rc came out for all devices and software releases so it must be ready I’m sure it will be today or tomorrow
that’s true. At the end we can only speculate here :) … but the new watch face may be a good sign that update may be coming today ????

There was a reason I looped you in!
