Dont force oculus client to open itself
No matter what I tried, the new Oculus client would reopen itself every time I closed it. I could see the screen in my rift light up, and hear sounds as I was loaded into home, with my rift sitting on a shelf, nothing triggering the proximity sensor (that im aware of). Eventually I was forced to roll back to stop it.
Thanks for submitting this feedback through UserVoice. The behavior described in this post should not be occurring.

If you are still experiencing this issue, please open a ticket with Oculus support so we can investigate further. Thanks!
As a workaround, if you set the Oculus executable to run as administrator it won't open automatically ever (even if you put the headset on).
Did you have any web browsers open? Firefox and Chrome now have webvr enabled by default. Even if webpage has no webvr content I found that it would either launch steamvr/oculus until I disabled it in the browsers.
