OnePlus One users have been really patient for a while. First they had to wait ages for the Oxygen OS which is the first foray of OnePlus in the world of creating its own ROM. While OnePlus may say that it developed the ROM to ensure a larger vertical stability, which means a device which has both hardware and software controlled from bottom up, you would know the real reason has been less than amicable split from Cyanogenmod which set them back a couple of months easily when it comes to updates.
.@jorgepenteado CM12s just passed certification today. Thanks for the patience, expect rollout in the next few days.

It was later announced that all those who are running CM 11s on their devices, will also get update to CM 12s, but that was delayed because of an issue with certifications. The certifications have finally come in, and if you do own the OnePlus One with CM 11, you can expect the update very soon. Carl Pei announced via his Twitter account that you can expect the update in coming days. When one of the followers asked if it could be done over the weekend, the response came in negative as apparently not everyone works on the weekend like the OnePlus team.
Those with the OnePlus One in India will receive the update too to CM 12 despite all the controversies around, and if you cannot wait, you can go ahead and flash Oxygen ROM which is on Android 5.0.2 already.
