Betfair magazine - Edge

Quick question, i have seen a new magazine advertised somehere, i think it was on betfair's promotional page although aren't sure but cannot find anything on it anywhere. I have searched onlione and googled several variations of the name etc.

If anyone has any info on it i would much appreciate it, ie how much, how often and where its available - that kind of thing.
