Apple's new macOS Catalina update fixes FaceTime issue, USB

Apple has launched a supplemental update to its 10.15.4 macOS Catalina update, which brings fixes to several issues, including a bug which prevented Catalina users from participating in certain FaceTime calls and a bug that rendered the USB-C port on a Mac unresponsive.

Since this is a supplemental update and not a standalone one, the new Catalina version has the same version number as the last one.
