Camera functions are broken after upgrade from 3.0.3.9 to 3.2.1.20. :-(

Is there any way to make it work again? Or should I just simply reflash the last known good version?

EDIT: upgrading to 3.2.0.12 (the next stop release after 3.0.3.9) also breaks the camera.

As far as I can see the latest full image is the 3.0.3.9. Are there any plans to publish a newer image? Another question: how to upgrade from 3.0.3.9 to any newer version without losing the camera?
