The Baked Data architectural pattern describes a pattern commonly used with Datasette where the content for a site is bundled inside a SQLite database file and included alongside templates and application code in a deployment to a serverless hosting provider.

Datasette 0.58 has new plugin hooks, a huge performance improvement for faceting, support for Unix domain sockets and several other improvements. Read the annotated release notes for extra background and context on the release.

Datasette 0.57 is out with an important security patch plus a number of new features and bug fixes. Datasette 0.56.1, also out today, provides the security patch for users who are not yet ready to upgrade to the latest version.

Django SQL Dashboard is a new tool that brings a useful authenticated subset of Datasette to Django projects that are built on top of PostgreSQL.

Datasette 0.56 has bug fixes and documentation improvements, plus some new documented internal APIs for plugin authors and SpatiaLite 5 bundled with the official Datasette Docker container.

Datasette 0.55 adds support for cross-database SQL queries. You can now run datasette --crossdb one.db two.db and then run queries that join data from tables in both of those database files - see cross-database queries in the documentation for more details.

sqlite-utils 3.6 adds similar features: a db.attach(alias, filepath) Python API method and --attach alias filepath.db command-line option, both for attaching additional databases in order to execute cross-database queries.

This new Video introduction to Datasette and sqlite-utils provides a full introduction to both Datasette and sqlite-utils in 17 minutes, including a live demo of creating a database from a CSV file and publishing it to Google Cloud Run.

Serving map tiles from SQLite with MBTiles and datasette-tiles. datasette-tiles is a new plugin that adds a tile server to Datasette, serving map tiles from databases that conform to the MBTiles specification. download-tiles is a tool for building these databases, and datasette-basemap is a plugin that bundles a 22MB SQLite database with OpenStreetMap tiles covering zoom levels 0-6 for the entire world.

Datasette 0.54 is out today. Highlights include the new _internal in-memory database exposing details of connected tables, plus support for JavaScript modules in plugins and add-on scripts. More commentary on this release is available in the annotated release notes.

Drawing shapes on a map to query a SpatiaLite database introduces the new datasette-leaflet-freedraw plugin, which adds support for drawing shapes on a map to specify a GeoJSON MultiPolygon that can be used to query SpatiaLite databases.

APIs from CSS without JavaScript: the datasette-css-properties plugin introduces datasette-css-properties, a highly experimental plugin that can output table rows and SQL query results as CSS stylesheets defining custom properties that can then be used to customize a static HTML page.

New on this site: a Datasette Tools directory and a search engine that covers documentation, tools, plugins, releases and more. The search engine uses Dogsheep Beta - I wrote about how that works in Building a search engine for datasette.io.

I wrote more about how this site works in Weeknotes: datasette.io, an official project website for Datasette.

Datasette 0.53 - datasette serve --create option, ?column__arraynotcontains= table filter, ?_header=off CSV option and updated links to reflect the new project website.

New Datasette project website - three years after the first release Datasette finally has its own website! The site includes project news, a plugin directory, use-cases and examples. The site is implemented using Datasette custom templates, and the source code is available on GitHub.
