1.9.0Melbourne−1.4Real-world reformActivity Centres Program Stage 2 / Amendment GC285, gazetted 2026-07-22 — Prahran/South Yarra + 8 other centres' catchments rezoned to HCTZ1/HCTZ2. Residential area ~unchanged; restricted share drops 49.73%→49.26% GCCSA as HCTZ1/HCTZ2's height allowance is materially looser than what preceded it. Real-world policy2026-07-22
1.8.0Canberra−0.1Coverage changeACT Territory Plan zones/roads/blocks refetched — small live-vs-local deltas, but no specific amendment was identified/dated; our local copy catching up to an already-current live service, not a new change in the law; heritage_scoped.geojson left untouched, no reproducible derivation2026-07-20
1.8.0Hobart−0.3Coverage changeTAS zone/overlay/heritage layers refetched; legacy Interim scheme winding down as councils' Local Provisions Schedules take effect. Code Overlay fetch briefly picked up new non-heritage sub-types (Significant trees, archaeological potential, precincts) alongside Local heritage place, tripling the heritage-control share — Ethan called it back to Local-heritage-place-only (a methodology/scoping fix). Also: Hobart Commercial Zone under the HOB-S6.0 Specific Area Plan now counts as residential (Mixed Use, 4 storeys) — a real, pre-existing planning provision we'd been missing, not something that just changed.2026-07-20
1.8.0Adelaide−0.1Real-world reformSA Planning & Design Code amendment refresh + rebuilt the derived LU-x-Zones layer, which had no prior committed script.2026-07-20
1.8.0Perth−0.6Coverage changeR-Codes/CPS2/heritage layers refetched from live services — small live-vs-local deltas, but no specific amendment was identified/dated; our local copy catching up to an already-current live service, not a new change in the law2026-07-20
1.8.0Brisbane+0.0Methodology refinementBCC/Moreton Bay zoning+heritage refetched. Fixed a ZONE_PREC_ field-collision bug that turned out to be a no-op (old export already resolved it the same way); the real bug was NULL-vs-zero handling on no-precinct zones, which briefly (mis)moved le-2-storey to 60.6% before Ethan traced it and the fetch script was fixed to zero-fill — final le-2-storey is back at 82.64%, unchanged from pre-#590.2026-07-20
1.8.0Melbourne−0.3Real-world reformVIC zones/heritage overlay/register refetched; new PRZ zone classified Mixed Use / unknown-height rather than excluded.2026-07-20
1.8.0Sydney−0.1Coverage changeNSW Zones/HOB/FSR/Heritage refetched from live services — small live-vs-local deltas, but no specific amendment was identified/dated; this reads as our local copy catching up to an already-current live service, not a new change in the law2026-07-20

1.5.0Brisbane+0.4Methodology refinementPDA re-add clipped to exclude open-space/recreation base — golf course/parks no longer counted as unrestricted residential2026-07-13
1.4.0Sydney−0.4Methodology refinementR2-in-TOD carved out of low_density — TOD R2 gets the SEPP apartment/22m uplift, no longer low-density; union −0.15pp, ≤2-storey unchanged2026-07-12
1.3.1Sydney−0.0Methodology refinementHOB overlap precedence fix — overlapping HOB polygons are same-control precinct stacking, most-permissive wins; GCCSA HR ticks 86.9% → 86.8% on the rounding boundary, all moves sub-0.01pp citywide2026-07-12
