 Following data from Photos Version 6.0 (300.8.140) on Big Sur version 11.0 Beta (20A5343j)
 
+The biggest change appears to be that `ZGENERICASSET` renamed `ZASSET`.  Some of the primary keys changed (e.g. `ZASSET = 3` instead `ZGENERICASSET = 34`) which means some of the mappings for foreign key lookups need to change.  The main tables used by osxphotos though don't have a lot of changes beyond renaming `ZGENERICASSET` which means porting the code to work with the new database won't be terribly hard.
