datasette 1.0a40

16th September 2026 Release datasette 1.0a40 — An open source multi-tool for exploring and publishing data Same security fix as 0.65.5, plus some neat new features and bug fixes: Plugins can now launch and manage background tasks using the new datasette.add_background_task() method. Thanks, Alex Garcia. I've migrated Datasette to httpx2 for features like the internal datasette.client.get() method.
