Catalina 10.15 Beta 1

Apple is totally on the ball with their new macOS Catalina. They just released 10.15 Developer Beta 1. I have installed it, but there are no obvious changes or additions. I am sure it is a maintenance release, bug fixes and stuff like that. Although, I have not noticed the first release of Catalina to be very buggy, it seems to be running well after I got done giving all kinds of Apps Access to the machine.
