you are right ... those numbers are not a good pointer. I found this repo, and 
from the checkin dates it looks like 10.2.4.97 is indeed way older (from 
September 2015) than 10.2.4.70.42 (April 2016):

https://source.codeaurora.org/quic/qsdk/oss/firmware/ath10k-firmware/log/10.2.4

I would agree that Changelogs would be helpful.

Thanks for the clarification. We will then stick to the 70's branch then.

Does anyone have pointers for the other questions? :) I would believe hat many 
people would be interested in running AP + Mesh encrypted at the same time (at 
least in the open source community ...).

Thanks,
