Synology has just recently released a new update, DSM 5.2 -5592 Update 3. While it’s possible to update I don’t recommend it before a new boot image is released.
If you don’t care and like to live on the edge please note the following:
After installing the update (just update straight from DSM), the volume will most likely be removed due to abnormalities. Just reboot XPenology and your volume should be back, but be aware that users home directory, CloudStation and other services might be deactivated after the upgrade. Just turn them back on and everything else should work as usual.
