+Email Checkout Receipts
+^^^^^^^^^^^^^^^^^^^^^^^
+This feature allows patrons to receive checkout receipts through email
+at the circulation desk and in the Evergreen self-checkout interface.
+Patrons need to opt in to receive email receipts by default and must
+have an email address associated with their account. Opt in can be staff
+mediated at the time of account creation or in existing accounts.
+Patrons can also opt in directly in their OPAC account or through patron
+self-registration. This feature does not affect the behavior of
+checkouts from SIP2 devices.
+
+Patrons can opt in to receipt email checkout receipts by default via
+a new "Email checkout reciepts by default" patron setting.
+
+This feature also enhances the patron staging tables so that patron
+settings can be chosen during self-registration.
+
+The web staff interface's checkout screen now includes a "Quick
+Receipt" button that allows staff members to generate a receipt
+at any time.
