The latest XAMPP version does not install the latest phpMyAdmin, ence it has to be manually upgraded.
It’s a very simples task really. We just have to backup our current config.inc.php file in our current phpmyadmin dir, and download the latest version at phpMyAdmin.net.
Then what I did was rename the phpmyadmin dir to phpmyadmin_OLD, and extract the new phpMyAdmin. The new dir has to be renamed to phpmyadmin, and then I copied the old config.inc.php to this new dir.
After this, all we have to do is start the MySQL server, go to phpMyAdmin and we should have the latest version.
