Released September 24th, 2020.
We thought 10.15.6 would be the last major Catalina version with further updates limited to Supplemental Updates or Security Updates only. Today, Apple proved us wrong and released 10.15.7 update today! Safe to install on our Hacks without specific issues or surprises to expect.
Security update 2020-005 for High Sierra (17G14033) and Mojave (18G6032) also released at the same time.
