( #1150 ) \n                 This will support future improvements such as a searchable, paginated homepage of all available tables. \n                 You can explore an example of this database by  signing in as root  to the  latest.datasette.io  demo instance and then navigating to  latest.datasette.io/_internal . \n                 Plugins can use these tables to introspect attached data in an efficient way. Plugin authors should note that this is not yet considered a stable interface, so any plugins that use this may need to make changes prior to Datasette 1.0 if the  _internal  table schemas change.", "breadcrumbs": "[\"Changelog\", \"0.54 (2021-01-25)\"]", "references": "[{\"href\": \"https://github.com/simonw/datasette/issues/417\", \"label\": \"Datasette Library\"}, {\"href\": \"https://github.com/simonw/datasette/issues/1150\", \"label\": \"#1150\"}, {\"href\": \"https://latest.datasette.io/login-as-root\", \"label\": \"signing in as root\"}, {\"href\": \"https://latest.datasette.io/_internal\", \"label\": \"latest.datasette.io/_internal\"}]"}
