Quick update (beta channel):
1.1.1 desktop update deployed with minor background fixes. Many phone specific fixes, extended diagnostic mode + blog post coming tomorrow (2016/07/29).
If you get "Update failed" exit Steam before the RiftCat update begins.
Finally we can release our multi-channel updates. It took us longer than expected but we wanted to make sure that we don't mess anything up with updater because having bugs in update process may result in forced reinstall and we don't want to waste your time with that.
We wrote about it in our previous blog post but here's a copy-paste description of update channels:
This will not always work. For example, VR SDKs, graphics drivers or some other condtions can change in a way preventing backwards compatibility. We're not always in control but we will try our best to give you the most options.
