There was supposed to be an update come out on September 22 for Windows 11?  We have not seen anything yet.  Has anyone else?

The september 22 release was the preview release for the full monthly update.  I installd it on one of our test machines and the new TZs are there.

The regular cycle will be Oct 13 (patch Tuesday).
