Installed building 20191224 onto SD. uEnv.ini and extlinux.conf are modified to point to the correct dtb for my Khadas Vim3.
I notice that all the audio passthrough options are now gone.
In terms of Audio Output Device, I can only choose between 'ALSA: G12A-KHADAS VIM3, Analog' and 'Pulse: Default, Bluetooth Audio (PULSEAUDIO). I think there used to be an option for HDMI.
