The Clarity team implemented accessible outline highlighting for keyboard navigation. Previously, Clarity UI had overridden the default. There may be an impact for applications that had relied on the default override. In those cases, developers should implement their own override. The Clarity team removed the override because it hindered accessibility.
The visited link text color has been changed. Just a heads up that there's a slightly different shade of purple in use. Those who were already overriding the visited link text color should not be impacted.
