New release is out based on AOSP10/aarch64. After testing and discussion on SFO, I am switching the port to AOSP10/aarch64 base and will continue releases on that base from now on.

While it is inconvenient to reflash the device and set it up again, I think a better camera does justify it. On my side, it will be just too much work to support multiple bases / ports, so I had to make a choice.
