I noticed on the Release Blog on the download page that the Oculus shows has 0.1.8 while DayDream is still on 0.1.7.Well scratch that I just got a new version in the Google play store as I looked at tit to confirm version against Steam. However the Release Blog still show 0.1.7 :) .
I also noticed the Steam has 0.1.7.3(12) and the Blog Does not mention anything about Rift vs Vive. I have sound issues for videos on the Steam version but not my Google Daydream so I am hoping that something is coming soon and perhaps you have a general time-frame on when we might see it? It has been hard for me to tell what is going on with what is on Steam because the update history page is blank and without a Mixed Reality Version, this is the only version I can use for my PC headset.
