WordPress 4.9.3 is a maintenance release and was originally scheduled to be available on January 30th. However, due to ongoing tickets and a short time frame to test the release candidate, it has been pushed back to February 5th.
WordPress 4.9.3 RC 1 is available for testing. This release removes JSHint from the code editors due to conflicts with the GPL License. If your code relies on JSHint from Core, developers encourage you to update it to use a copy of JSHint.
Other changes in 4.9.3 include, avoiding page scrolling when navigating the media modal, a handful of improvements to the customizer, and more. Please test WordPress 4.9.3 on a staging site and if you encounter any bugs, you can report them on the Alpha/Beta section of the support forums.
