[GigaSoul]

I am trying to find out when this firmware was released: (JR6150 / R6050 Firmware Version 1.0.1.26) 

I want to know the timestamp for when the firmware was made available to the public.

   Why?

   If you believe the date+time info on the files in the archive, then
I'd say after about 2019-12-19:00:00 (local time, someplace).
