> 8. If you haven’t used an app that you installed on your device in a while, you may not want it to keep accessing your data. Android will now “auto-reset” permissions for your unused apps and notify you accordingly. You can always decide to re-grant the app permissions the next time you use the app.
> 9. With additional Google Play system update modules, even more security and privacy fixes can be sent to your phone from Google Play, in the same way your apps update. So you’ll get these fixes as soon as they’re available, without having to wait for a full OS update.
8 seems like a rather wise and user friendly privacy concern (which might be annoying to power-users who set things up proactively and don't want their configurations messed with, yet overall a great improvement).
9 has me worried about variants of android like Lineage or ParanoidAndroid where the play store isn't included automatically. This forced reliance upon the play store for security sensitive updates is devastating for de-googled device feasibility. It will make more sense for developers to not support devices without Google Play, effectively shoehorning alternatives out of the usable, secure devices realm.
