I have a OnePlus Two, and yes, there are CyanogenMod builds for it, I've been running them for the past year. Just last week, the updates started coming through the in-OS updater, rather than me having to download and flash ROMs. I haven't been bit by any bugs or even particularly rough edges for the past three months or so.

I assume these builds will eventually get blessed by CM -- maybe they already have?

The thread I keep an eye on:
