[MaintenanceAssetChangeEvent](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_associated_objects_change_event.htm "A ChangeEvent object is available for each object that supports Change Data Capture. You can subscribe to a stream of change events using Change Data Capture to receive data tied to record changes in Salesforce. Changes include record creation, updates to an existing record, deletion of a record, and undeletion of a record. A change event isn’t a Salesforce object—it doesn’t support CRUD operations or queries. It’s included in the object reference so you can discover which Salesforce objects support change events.") (API version 48.0) Change events are available for the object. [MaintenanceAssetFeed](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_associated_objects_feed.htm "StandardObjectNameFeed is the model for all feed objects associated with standard objects. These objects represent the posts and feed-tracked changes of a standard object.") Feed tracking is available for the object. [MaintenanceAssetHistory](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_associated_objects_history.htm "StandardObjectNameHistory is the model for all history objects associated with standard objects.
