This is a new minor upgrade. The upgrade is available only as a firmware upgrade.
How to upgrade
To upgrade a running system, make sure you don't have any activities running such as uploads, downloads, print jobs etc. Then log in as admin in web-ui. Choose "Settings" menu entry. Choose "Software update" in the sub menu. Press the "Update system" button.
Since the update service depends on root access to the MySQL database, if you have changed the default password the update will fail. If it has been changed, run the update from the command line. Default options should be ok, but you need to provide your MySQL root password.
Install
To (re)install a system please read the manual, section "INSTALLING & REINSTALLING SOFTWARE".
