CISSCAL 3.8 upgrade
Apparently there is an ISS IDL CISSCAL version 3.8 now, since May 2016 (https://pds-rings.seti.org/cassini/iss/index.html)
Could the ISIS version be updated to that, for consistency?
From the source code I read that the current implemented version is 3.6.
Extra: It seems that your Software version entry for 3.5.2 errors on the year, should be 2018, I think?
