+Copy Status "Is Available" Flag
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Adds a new boolean field for copy statuses to indicate when copies having
+a given status should be considered available. The field has 2 main effects:
+
+1. Checking out an "available" copy will no longer result in an override-able
+ "COPY_NOT_AVAILABLE" alert for staff. The copy will checkout without
+ status warnings.
+
+2. "Available" copies will appear in catalog searches where "limit to
+ available" is selected as a search filter.
+
+By default, the "Available" and "Reshelving" statuses have the "Is Available"
+flag set. The flag may be applied to local/custom statues via the copy
+status admin interface.
