 ### Added
-
-### Changed
+- Added the `BETA List Maintenance` ([GET /account/maintenance](/api/v4/account-maintenance)) endpoint. This new beta endpoint allows you to view a collection of maintenance objects for any entity you have permissions to view. Currently, Linodes are the only entities available for viewing.
 
 ### Fixed
 - A bug was fixed that would result in a 500 error when filtering domain records by a non-existent tag. This will now return an empty 200 respone.
