+Conditional Negative Balances
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Evergreen sites will now have more control over whether a negative balance can
+be applied to a user's billing record and when that negative balance can be
+applied. Through a series of Library Settings, a site can prohibit negative
+balances on bills or can allow those negative balances to be applied for a
+specific period of time after a lost or overdue bill is charged to the user.
+Sites can set a default for all types of bills or can apply distinct settings
+for lost bills and for overdue fines. The more specific settings will override
+the default.
+
+In addition to the new library settings, the system now has a new void payment
+type. Staff will continue to be able to void a bill in the same way they always
+have, but instead of marking the bills as voided, void payments will be applied
+in the amount of the voided billings.
