More complete transport coverage
improvement
Rail, metro and bus access now use authoritative national data with complete, consistent coverage across England, Wales and Scotland, in place of a live lookup whose quality varied by area. Transport scores no longer depend on how well an area happens to be mapped.
Amenities served from a stored snapshot
improvement
Amenity counts (schools, food and drink, healthcare, shops, parks and leisure) are precomputed per area and served from the store rather than a live query, so values are stable request to request.
