Apple today quietly released an updated version of macOS Mojave 10.14.5, which is designed for 15-inch MacBook Pro models that feature a T2 security chip, aka the 2018 and 2019 machines.

The new version of the software can be downloaded through the "Software Update" section of System Preferences on all compatible Macs.

According to Apple's release notes, the new software addresses a "firmware issue" impacting Macs with a T2 chip. Apple provided no additional detail, so we don't know what the specific firmware issue might be, but we may get more information when the security notes become available.
The MacBook Pro Supplemental Update addresses a firmware issue affecting 15-inch MacBook Pro computers with T2 Security Chip, and is recommended for all users.

For detailed information about the security content of this update, please visit: https://support.apple.com/kb/HT201222
Apple released the macOS Mojave 10.14.5 update on May 13, adding AirPlay 2 support for sharing music, photos, videos, and more from the Mac to AirPlay 2-enabled smart TVs from companies like Samsung, Vizio, LG, and Sony.

Minor Apple News+ interface changes were included, allowing users to follow a magazine directly from the catalog browsing view, and there were improvements to audio latency on 2018 machines.

The big question is when will they fix the Mac Mini 8,1 display problems? There are two I know of: monitors not returning after sleep, and monitors not waking on boot.

Is there a way to tell if I have gotten the supplemental update? I updated to 10.14.5 late Monday, "about this Mac" shows 10.14.5 and software update says there is no update available. Will the supplemental update indicate anything different than 10.14.5? I have the 2018 15" MacBook Pro with touch bar.

Usually the version number itself doesn't change for a supplemental update. I don't have an MBP anymore so I can't check this specific one, but the build number for normal 10.14.5 is 18F132. See if your build number might be incremented now. If this was just an update to firmware, it's possible they didn't update the build itself, though.

I'm a rolling stone.

You should re-format with fresh install

No, why, a fresh install (almost) never helps, there are other ways to "debug" macOS.
I started on the very first 10.0b, I never reinstalled the OS, update over update, there were problems/bugs, I solved it myself or just waited for an update.
Yosemite was one of the worst ones I had, had Wifi issues for most of the year until the new OS version, reinstalling would have been wasting time.

You’ll see it in Software Update as something new and you’ll be able to tell
