Link Ableton to Rekordbox

i was really looking forward to the next update 5.8.2  specifically for the feature Ableton Link  which was anounced some years ago.  requested so many times. 
as is is already present in 

Ableton Link went open source back in 2016,  all other DJ-software apps already have it.  and even the  DDJ-1000 SRT version of rekordbox already has it.
Can anyone PLEASE tell me when we are going to get Ableton Link finally?
