CM13.0 UNofficial - Watching the code being merged from Android M AOSP

I am not connected with CM - other than as a fan and long time user - so this is UNOFFICIAL.

I have just bought a second hand nexus 5, having cancelled my pre-order nexus 5x - I could not justify the cost

So as a long time CM12.1 user on my now retired nexus 4, I am watching the code merges from AOSP to CM13.0 (Marshmallow)

I noticed that an important feature rolled by - DOZE mode the battery saving feature of M - looks like it might well turn up fully supported in CM13.0

The notes from the developer here.

Refer to including doze mode as described here

I am watching the code merges roll by for CM13 in general here.
