Text to go in the release notes:
The `useDaysMode` system preference has been enhanced to include an additional option.
This allows libraries to dictate that if the library is closed on the usual due date, the loan period should be pushed forward to the next open day which is the same day of the week.
For example : If an item should be due back on a Tuesday but that particular Tuesday is closed, then instead of it being due back the Wednesday (usual behaviour when due date is pushed forward to next open day), it would actually be due back the next available open Tuesday.
**Note**: This preference setting only works in multiples of 7.
