After testing the nightly image from August 19th on my Odroid C2, I have some observations.
1. Kodi hangs frequently when seeking an h265 encoded video. This doesn't happen with h264.
dmesg shows:
meson-vdec c8820000.video-codec: Couldn't find ref. frame 4294967184
2. Some sporadic reboots, when playback starts, maybe at other times too. I haven't had time to check for clues with an uart cable.
3. No /flash/boot.ini file?
4. Support for common led triggers missing from kernel (ie: timer, disk, etc)
