The number of Android flagships running Oreo at all is already slim, but those using Android 8.1 are even fewer. Now when it comes to OnePlus' older devices like the OnePlus 3 and OnePlus 3T, there's no official word on when those will be updated, but they will likely be getting Android Oreo at some point.
As far as the codename of the OnePlus 6 is concerned, the device is expected to be called as "enchilada" which comes after the OnePlus 5T was codenamed as "dumpling", OnePlus 5 as "cheeseburger" and OnePlus One being codenamed as "bacon".
Interestingly, this update also includes the security patch for February 2018 from Google. If you work with either OnePlus 5 or OnePlus 5T, you should register for the open beta program since the software bits are available only for registered users.
You will receive the update over the air only if you have already flashed another OxygenOS beta build. Users should note that this Android 8.1 Oreo update is for those who on the beta version of OxygenOS, and those on the stable build will not see the new update.

Finally, the update has brought some new clock faces for the ambient display.

With the update in its fourth beta, we can expect the stable version to be out soon.
