Updated my old Allsky which operated perfect, perfect exposures with ZWO ASI178MC. After the ALLSKY update last night and entering old json settings in the new Settings_ZWO . json Reboot Night time Images are VERY dark
sudo service allsky status show ZWO is detected

What changed to make my images very dark ?

Update to my posting 2021-07-10 10PM settings_ZWO.json definetaly loads and runs . Verified by changing the Gain Entry to Different values then displaying log.txt.

Looking at the captured image the configured TEXT entry 'ZWO-1' does not display. The exposure interval never changes from .006 Seconds

It looks like the program is not reading the settings file correctly or settings_ZWO.json is corrupted in the down load.

The Hardware is fine, I Removed the SD card with the new version and re-installed the SD with the 2year old version and everything works fine.
