+### Added
+- 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 a 200 response with an empty pagination result. 
+- Previously, NS and CNAME records could be created for each other, resulting in errors when the zone file is rendered. If this is attempted now, the record creation will fail with a "Record conflict" message.
+- Changes were made to the ([GET /linode/instances](https://developers.linode.com/api/v4/linode-instances)) endpoint to improve response time.
