Just updated, no problems during the process.
It would be nice to see the "fixed issues" from the previous version in the changelog. Now this doesn't need to be really detailed but should include most important fixes from known issues.
I also don't see the new alerts when a new device is connected to the network. Does Dual Band routers which simultaneously run two different WiFi bands at the same time have something to do with this? I would doubt it.
I've also said this earlier. Regarding password protecting Avast through Settings, the option "Require password only to access settings" still allows Protection Shields to be disabled via the UI and the tray icon. I don't like this approach, it should prevent disabling of protection features. The other option of "Require Password to Open Avast" does work but what if a user who did not know the password etc would like to run an on demand scan etc?
