Plugins are invited to use this as a private database to store configuration and settings and secrets that should not be made visible through the default Datasette interface. Users can pass the new   --internal internal.db  option to persist that internal database to disk. Thanks, Alex Garcia.

If you want to customize EVERY row template with some additional\n                        content you can do so by creating a row.html template like this: \n                     {% extends \"default:row.html\" %}\n\n{% block content %}\n<h1>EXTRA HTML AT THE TOP OF THE CONTENT BLOCK</h1>\n<p>This line renders the original block:</p>\n{{ super() }}\n{% endblock %} \n                 \n                 \n                     --static  option for datasette serve ( #160 ) \n                     You can now tell Datasette to serve static files from a specific location at a\n                        specific mountpoint. \n                     For example: \n                     datasette serve mydb.db --static extra-css:/tmp/static/css \n                     Now if you visit this URL: \n                     http://localhost:8001/extra-css/blah.css \n                     The following file will be served: \n                     /tmp/static/css/blah.css \n                 \n                 \n                     Canned query support. \n                     Named canned queries can now be defined in  metadata.json  like this: \n                     {\n    \"databases\": {\n        \"timezones\": {\n            \"queries\": {\n                \"timezone_for_point\": \"select tzid from timezones ...\"\n            }\n        }\n    }\n} \n                     These will be shown in a new \"Queries\" section beneath \"Views\" on the database page. \n                 \n                 \n                     New  datasette skeleton  command for generating  metadata.json  ( #164 ) \n                 \n                 \n                     metadata.json  support for per-table/per-database metadata ( #165 ) \n                     Also added support for descriptions and HTML descriptions. \n                     Here's an example metadata.json file illustrating custom per-database and per-\n                        table metadata: \n                     {\n    \"title\": \"Overall datasette title\",\n    \"description_html\": \"This is a <em>description with HTML</em>.\",\n    \"databases\": {\n        \"db1\": {\n            \"title\": \"First database\",\n            \"description\": \"This is a string description & has no HTML\",\n            \"license_url\": \"http://example.com/\",\n        \"license\": \"The example license\",\n            \"queries\": {\n              \"canned_query\": \"select * from table1 limit 3;\"\n            },\n            \"tables\": {\n                \"table1\": {\n                    \"title\": \"Custom title for table1\",\n                    \"description\": \"Tables can have descriptions too\",\n                    \"source\": \"This has a custom source\",\n                    \"source_url\": \"http://example.com/\"\n                }\n            }\n        }\n    }\n} \n                 \n                 \n                     Renamed  datasette build  command to  datasette inspect  ( #130 ) \n                 \n                 \n                     Upgrade to Sanic 0.7.0 ( #168 ) \n                     https://github.com/channelcat/sanic/releases/tag/0.7.0 \n                 \n                 \n                     Package and publish commands now accept  --static  and  --template-dir \n                     Example usage: \n                     datasette package --static css:extra-css/ --static js:extra-js/ \\\n  sf-trees.db --template-dir templates/ --tag sf-trees --branch master \n                     This creates a local Docker image that includes copies of the templates/,\n                        extra-css/ and extra-js/ directories.
