Thanks for the heads up about 5.9. Looks like it honestly should be called 6.0 or 0.9. I have close to 400 lines of Additional CSS in Customizer and no desire to be a beta tester. So prudents requires that I move on. Easy Updates Manager should keep me safe until I decide on a new course. Sad that WP did not do this the right way and fork the product. It sure was great while it lasted.
