DSM Updated to Version 5.2-5592

Synology began July with an update to Disk Station Manager (DSM) which is now at version 5.2-5592. There’s no new features, just stability and security fixes. The security fixes alone are reason enough to do the update as soon as possible.

I’ve successfully updated DSM models DS212+, DS1511+, DS415+ and DS1815+ without a problem. It does require a reboot of the NAS once the update is done.
