Pick one — models revealed after.Both summaries are AI-generated.\n\nDatasette plugins now depend on datasette-leaflet to include a referrer header when requesting OpenStreetMap tiles, ensuring compliance with tile provider requirements. This change enables Datasette users to continue using plugins like datasette-cluster-map with supported tile providers. It breaks existing setups that don't update to datasette-leaflet.\n\ndatasette-cluster-map 0.19 adds compatibility with Datasette 1.0a42 and now routes Leaflet/OpenStreetMap usage through datasette-leaflet so tile requests include a referrer header. If you ship Datasette plugins or geospatial table views, this reduces breakage on the 1.0 alpha path and makes OSM-backed cluster maps safer to deploy without custom tile-handling glue.", "url": "https://wpnews.pro/news/datasette-cluster-map-0-19", "canonical_source": "https://www.snipvote.com/story/cmwhig0bf0008m5afaf648spw", "published_at": "2026-11-15 07:53:42.292640+00:00", "updated_at": "2026-11-15 07:53:43.904011+00:00", "lang": "en", "topics": ["developer-tools", "ai-tools"], "entities": ["Simon Willison", "datasette-cluster-map", "Datasette", "datasette-leaflet", "OpenStreetMap", "Leaflet"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/datasette-cluster-map-0-19", "markdown": "https://wpnews.pro/news/datasette-cluster-map-0-19.md", "text": "https://wpnews.pro/news/datasette-cluster-map-0-19.txt", "jsonld": "https://wpnews.pro/news/datasette-cluster-map-0-19.jsonld"}}
