The macOS Catalina 10.15.6 beta can be downloaded from the Software Update mechanism in System Preferences after the proper profile has been installed from the Apple Developer Center.

There's no word yet on what improvements the new update to macOS Catalina brings, but it likely includes performance improvements, security updates, and fixes for bugs that weren't able to be addressed in the previous update. No new features were found in the first beta, but we'll update this article should anything new be found in the second beta.

After using Windows 10 for a while, Catalina looks so boring o_O. If you really love macOS, stay away from Windows, no matter what.
I beg to differ. I have to use both and I find Windows 10 to be...annoying. The UI is extremely inconsistent, going back and forth between the "new" look that isn't so new, and items that look like they're from 20 years ago in Windows 2000. Some tasks are buried maddeningly deep in menus or controls. Thanks but no thanks.
