WordPress 4.9.6 Release Candidate 1 is available for download and addresses some of the issues that have been reported in beta 1. Since the beta’s release, there have been 30 bugs fixed.
One notable bug fix is that site administrators now receive an email when a Personal Data Export/Removal request is confirmed. In a future version of WordPress, it’s possible that the notification bubbles will be extended to display confirmed requests.
A full list of changes in this release can be found on Trac. This minor release needs more testing than usual due to the privacy tools and enhancements introduced. Please test 4.9.6 on staging site or local server and if you encounter any issues, report them on the Alpha/Beta/Release Candidate section of the forums.
