Hmm so I tried a factory reset of the Hub and some things seem to have updated;
The firmware version has updated from SG4B100021
D0 to SG4B100021
ECThe GUI version has updated from 1.25.1 to 1.28.3
And the firmware update date has gone from 27/04/16 to 12/05/16
And by the looks of it the Event Log now displays the most recent chnages at the top instead of adding it on the bottom to a long list
