The summer is over, but as a small consolation there is a new version of XAMPP. And this time, we were able to update all existing four XAMPP versions.
In this version we updated: MySQL (5.0.67), PHP (4.4.9), and phpMyAdmin (220.127.116.11). The Solaris version even got a total of 14 packages updated.
