Hi all,
It appears that phpMyAdmin released an updated version yesterday, 4.7. cPanel v64 shipped with 4.6.6 bundled as an RPM (Apologies for the release note being out of date, we're fixing that now).
We would need to do some patch work to update cPanel's bundled phpMyAdmin version to 4.7. We don't currently have the product-infrastructure to ship updated 3rd party tools faster, but it is something we are discussing strategies for future versions of cPanel.
