I sent in MKB20_v76_Ghost_in_the_Shell_671D.tgz on Sunday.
Is there an easy way to tell when there is a new version of hashed keys database?

MakeMKV checks for a new version every time it needs one, assuming you've allowed it.

The log shows when it tries to get a new copy, and whether or not it was successful.
