## Summary Allows attachments to be loaded on-the-fly in the content extension if they are not present. ## Link to pull request in Documentation repository Documentation: home-assistant/companion.home-assistant#510 ## Any other notes - Adds `lazy` as an option to the `attachment` dictionary. When true, this prevents the attachment from being downloaded except when displayed in the content extension. This is similar, but not identical, to hide-thumbnail. Hiding the thumbnail still uses the internal storage of the notifications which are limited to e.g. 50mb. However, we'd still want to pre-load those attachments even if the thumbnail is hidden. - Retries non-lazy attachments which failed due to a network error when the content extension opens.
