The new macOS Catalina beta can be downloaded using the Software Update mechanism in System Preferences after installing the proper software from the Developer Center.
macOS Catalina 10.15.4 includes Screen Time Communication Limits, a feature first brought to the iPhone in the iOS 13.3 update, and it brings a new Head Pointer Accessibility option that allows the cursor to be controlled with head movements using the Mac’s camera.

Though not directly related to macOS Catalina 10.15.4, Apple is adding a new universal purchase option for macOS and iOS apps, which will allow Apple device users to purchase one app that works across multiple platforms.
