Version: [4796] Cityseer 5.6.1 Experimental

5.6.1
- Demand Betweenness: new advanced Participation parameter (stay-home
outside option) making trip generation accessibility-elastic; 1 =
everyone travels (unchanged behaviour), walking mode shares suggest
0.15-0.3
- Demand Betweenness: origins and destinations are assigned via the
shared data-layer workflow (nearest street, offsets included in routed
distances) instead of a nearest-node snap
- All algorithms: representation-aware assignment on the dual graph
(single nearest street with direction-of-approach offsets), so
accessibility, mixed-use, and statistics distances shift slightly

5.5.0
- No change to plugin behaviour: the plugin pins the established
cleaning parameters, so networks, caches, and outputs are identical to
5.4
- The cityseer library gains construction-time cleaning parameters and
universal segment-length weighting (library API only)

5.4.1
- Python 3.14 support; the OS Open Roads reader moves from Fiona to
pyogrio
- rasterio bumped to >=1.4.4 (support for older Intel Macs dropped)

5.3.1
- Accessibility and Mixed Uses skip features with a missing land-use
category instead of erroring
- QGIS 4 compatibility: set qgisMaximumVersion and remove the
deprecated supportsQt6 flag

5.3.0
- New Demand Betweenness (OD Flow) algorithm: spatial-interaction flow
allocation from weighted origins to weighted destinations, routed
along shortest paths
- New Mixed Uses algorithm: Hill diversity (q=0,1,2), Shannon entropy,
and Gini-Simpson within distance thresholds
- Statistics accepts multiple numerical fields in one run and only
computes the selected statistics
- Advanced distance-decay expressions for Accessibility, Statistics,
and Mixed Uses
- Advanced time thresholds (minutes with walking speed) as an
alternative to metre distances on all algorithms
- Adaptive per-node sampling (polled reach pilot, Hoeffding
probabilities, work test) replacing the deterministic distance-based
schedule; off by default with an advanced epsilon control
- Hillier metric labelled "improved closeness"; default metric for
simplest-path closeness
- Compatibility with the QGIS 4.2 processing GUI (AlgorithmWidget
replaces AlgorithmDialog)

4.25.0
- New CityNetwork class-based API wrapping network construction,
centrality, and layers
- Fast dual graph builder bypassing NetworkX for direct
LineString-to-NetworkStructure construction
- Incremental diff-based network updates preserving unchanged node
indices
- Feature status tracking (active, deleted, invalid_geometry,
duplicate, short_self_loop)
- Save/load with parquet persistence and full state roundtrip
- Boundary polygon support for automatic live node assignment
- Construction from GeoDataFrame, WKTs, NetworkX, or OSM

4.24.1
- Fixes sampling behaviour for live vs dead nodes

4.24.0
- Endpoint-aware angular centrality using doubled state-space on dual
graphs
- Brandes multi-predecessor backpropagation for angular betweenness
- Dynamic slope penalty using Tobler's hiking function for z-aware
networks
- Cycles metric redefined as non-tree edges (circuit rank) in the
local reachable subgraph
- Add simplest-path tolerance using the same relative-percentage
semantics as shortest path

4.23.9
- Fix betweenness threshold to use agg_seconds consistently with
closeness
- Use prepared boundary geometry for faster containment checks

4.23.8
- Extract sampling module for lightweight imports in QGIS

4.23.7
- Set QGIS minimum version to 4.0

4.23.6
- Linting fixes

4.23.5
- Add Accessibility and Statistics algorithms
- Independent metric selection per centrality category

4.23.4
- Expose Hillier metric for angular closeness

4.23.3
- Update plugin homepage URL

4.23.2
- Fix betweenness tolerance: always update shortest distance on
improvement
- Default tolerance to 0 (exact shortest paths)

4.23.1
- Fix betweenness tolerance: accurate distance tracking prevents route
drift
- Fix betweenness overflow with tolerance-based path counting
- Switch metric output to f64 precision
- Add geometry validation and network cleanup on ingestion
- Default tolerance to 0 (exact shortest paths)
