We've been running 20.1.3 for 3 days now, and the only problem I have seen is "SATA error" during playback one time and during record one time. I changed the battery and restarted the camera and no more problems.
I have a small feature request:
To be able to route audio inputs to more them one audio track. Then you can have a hi gain on one channel and a low gain on the second channel as bakup.
..and I think Redalert is behaving wrong if you shoot using RAW view mode, and then make a adjustment in Redalert and then re-open same file, the adjustment is double applied.
