Rekordbox Update

I checked what version my rekordbox is currently running off and it said there is no newer version than the 1 I have which is 6.8.5 but that's not the latest version! 

Can anyone help me as to how I can update my software to the latest version which I believe is 7.09??

(Btw I do have the 'free' plan so not sure if that makes any difference?)
