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.

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.

So many of us are going to be waiting a month or two to see what other bugs are revealed in the 2019 models. I'm really hoping to get one later this year - wouldn't want to be an early adopter though.

On a tangential note, I wonder when iMacs will get T2 (or whatever version) chip?
When Apple finally decides to remove the spinning HDD from the entry level iMac SKUs. T2 don't work with spinning hard drives.
