Changes to how annotations are stored?

This is question specific to the Lacuna Stories version of the app: we have developed an Annotator plugin that injects colors into the annotation. In the older version of AS, these were saved as another field in the database. In the latest version of AS, however, they’re not appearing in the database anymore.

Were there any changes made to how AS stores Annotator data? That is, is there any field sanitization or other things going on? Perhaps I need to modify the data model so they’ll save correctly? Thanks.
