The devil is in the details of what specifically changed on a day-to-day basis. We tend to queue anything majorly distruptive for the start of the release cycle but in recent years even those have been quite smooth. For context, the family daily-driver RPi5 has been running dangerously unstable sounding "pre-alpha" K22 images for more than a year now without any drama. Hopefully K22 will start lurching towards release soon.
Ok thanks! Everything seem to be working nice. Will I be able to enter the stable channel, and update to LE13 via the official update function when its available, even if using a nightly build?
