August 2023 Security update

CalyxOS 4.12.0 - August 2023 is now available for all supported devices.

This update was released and worked on while a lot of the team were travelling.
As such, it was released to Security express right away, but held back from the other channels for stability, until we got a chance to test it more, collect feedback, and also be in a place to address any feedback.
Security express channel is meant for this - to get security updates out ASAP, with minimal testing done beforehand.
Stable will get them afterwards depending on how things go. Our goal is to test things out more, as much as we can, to provide an stable experience.

Calyx Institute is at DEFCON, Las Vegas. We have a booth in the vendor area, come visit us and say hi to some of the CalyxOS developers.
