## [4.0.0] - 2026-07-09 Demo City & Speed: synthetic city generator and hot-loop vectorisation (51 algorithms). ### Added - **Generate Demo City** (Reporting group) — deterministic synthetic town generator: streets, buildings, land use, POIs, facilities, demand, green, and a DSM raster, allowing all tools to be tried in one click. ### Optimized - **Speed optimization in visibility.isovist_field** — precomputes direction offsets once per field execution, speeding up the loop. - **Speed optimization in noise screening grid** — broadcasts distance calculations per row-chunk to avoid cell-by-cell loops. ### Testing - Engine unit checks grown to **360** (including exact feature counts for demo city, DSM elevation validation, cross-process determinism, and isovist_field bit-identity regression checks); end-to-end assertions at **282** on QGIS 3.44 LTR and QGIS 4.0.2.
