Apple also revised the macOS 10.14.6 delta and combo update downloads to include Supplement Update 2. The pages now dated Sept. 26th. (They did the same thing when the Aug. 26th revised Supplement Update was released. File sizes shown as of 9/26/2019 posting.)
Reminder to Users of Nvidia Web Drivers:
(There's been no Mojave Nvidia web driver updates yet, but a reminder to 10.13.6/10.12.6 users of Nvidia's web graphics drivers.)
New OS updates or later build numbers after Security Updates typically break currently installed Nvidia web graphics drivers. I'd switch to the default Apple driver and reboot before updating, if your card is supported with the default drivers. If not, wait for a Nvidia driver update. (Some non-Mac EFI cards are not supported by default OS X drivers.)
As usual I'll post download pages for Nvidia driver updates here and on the video topics page when spotted.
Nvidia Driver Updates - September 27, 2019:

iOS 12.4.2 release notes and details on security fix.
"available for iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPad touch 6th generation."
(What about iOS 12.4.1 users that do not want to update to iOS 13.1?
Only v13.1 appears in Software Update for devices compatible with v13, but running 12.4.1.)
