This was released a while back but you might have missed it which could be helpful is you need to move data in/out of AX. The update added data entities to AX and was released as KB3061216. So if you have CU10 or later you will find these entities already in your environment. If you are using the demo data environment in these release you might not see all the entities so you will have to refresh them. The easiest way is to just delete all the existing ones and open the target entities form and re-open and the list will be refreshed.

Here is a quick overview.

AX2012 R3 CU11

If you are looking for some more details on the entities that were released
