You are right

I was fixing the remaining rotation issues (and others including SELinux, offline charging, etc.) the last week, and started pushing out official nightlies yesterday.
You can download OTAs from
http://get.cm/?device=gts210ltexx. The page will be updated with a nice icon and such soon.
However, for now, please don't flash the CM recovery. It works, but the touchscreen is misaligned so you must use volume and power buttons for the time being. I'm personally using TWRP anyways and OTA installation works just fine.
The current bugs in the nightlies are these afaik:
1) Wireless screen casting is broken.
2) When sending a SMS, there will be an error saying it could not be delivered. This is wrong, it was delivered. Just a cosmetic issue here.
3) No fingerprint (won't fix this for a while).
EDIT:
The T810 will follow soon, so stay tuned if you're on the WiFi only variant
