Major update coming: firmware 8.x

So according to this blog post https://www.zerodayinitiative.com/blog/2021/10/14/adding-a-beta-nas-device-to-pwn2own-austin, the next major version of MCH will be 8.x.
It reads:

The updates will take you from 7.15.1-101 (current) to 7.16.0-216 and then the beta 8.0.0-301

Has anyone heard of what will be new with it?

In addition, the beta has been hacked during the November event: https://www.zerodayinitiative.com/blog/2021/11/1/pwn2ownaustin
