1.1.0 - Tools inside the dock:
- All sixteen analysis tools now live in a new Tools tab of the
02Route 3D dock instead of the Processing Toolbox. Pick a group and a
tool, fill its form, run it in the background with progress and
cancel, and open the HTML or DXF it wrote.
- The tools are pre-filled from the dock: Point A and B, the DEM, the
road network, the building layer, the last route layer and the
selected mobility profile.
- The plugin no longer registers a Processing provider, so 02Route 3D
tools are not available in the Graphical Modeler, batch dialog or
processing.run().

1.0.0 - Engineering and honesty:
- Tested on QGIS 3.28, 3.34, 3.44 LTR and QGIS 4.2 (Qt6) in CI,
including a check that every QGIS and Qt name the plugin uses exists
in each version.
- Fix: the MCDA Friction Surface crashed on QGIS 3.28 to 3.38 (it used
a QGIS 3.40 enum).
- The 3D viewer places the sun for a chosen date and solar time (same
formula as the shade analysis): building and tree shadows follow it;
at night the sun light switches off.
- Download failures (Overpass, Open-Elevation), cancelling and
projected CRSs are covered by tests; the viewer has unit, smoke and
pixel-baseline tests.
- Documentation no longer claims what the plugin does not do: the
elevation download is Open-Elevation (SRTM-based, not Copernicus 30
m), the viewer opens in the browser, the Pareto heat objective needs a
temperature raster.

0.9.0 - Deeper analysis:
- New algorithm Transit + Walk Route (GTFS): earliest-arrival journeys
by public transport (RAPTOR) with walking legs routed on the street
network; wheelchair users only get accessible stops and trips.
- Turn costs at junctions for cars, vans, trucks, bikes, scooters,
wheelchairs and strollers (left turns across traffic, sharp turns,
U-turns; trucks cannot take hairpins); drive-on-left option.
- Departure time: after dark walkers and cyclists avoid unlit streets
and main roads without sidewalks; the heat weight follows the sun.
- Isochrones follow the streets (land within a corridor of reachable
streets) instead of a hull that covered blocks, rivers and rail lines.
- Solar exposure computes real building shadows from a footprint layer
with heights, for any day of the year.
- Pareto routes prune with a lower bound for every objective (NAMOA*).
- Fix: two points beside the same long street segment no longer fail
to route.

0.8.0 - A truthful 3D viewer:
- Real terrain: heights sampled from the selected DEM around the
routes (sampled in the background task); without a DEM the viewer says
its surface is approximate.
- Elevation chart with distance and height axes, coloured by slope;
hovering it moves the walker in 3D and playback moves its cursor.
- Other profiles are drawn as coloured ribbons, with a comparison
table (distance, time, climb, max slope and differences).
- Routes now sit on the terrain: the route ribbon was squashed to 12
percent of its height and sank under hills.
- Renders only when something changes; trees instanced and buildings
merged (about half the draw calls).
- Basemap tiles placed correctly in Web Mercator, uploaded in batches,
with a DEM hillshade when offline.
- Live link to QGIS by server-sent events instead of polling every 1.5
s; unreadable route files and lost links are shown.
- Keyboard control (Space, arrows, Home/End, R), visible focus,
reduced motion, screen-reader labels.
- Snapshot at 2x or 4x and video with a caption and the map credit;
MP4 in Safari.
- Fixes: route ends at 0 m without a DEM (false 400 percent slopes),
chart values read at the wrong places, exaggeration not applied to the
route, capture buttons hidden behind the bottom panel.

0.7.0 - Faster routing:
- A 50 x 50 OD matrix on a 10,000-edge network takes about 7 s instead
of over a minute: one search per origin instead of one per pair.
- Routes on the same network reuse the built graph and every evaluated
edge cost (another profile, the OD matrix, a second click).
- Tighter, still exact A* bound; edge costs and raster samples
computed once per edge instead of on every visit; raster coordinate
transforms built once per layer.
- Snapping finds the nearest node per network component in one pass
and now covers the full snap radius at high latitudes.
- Pareto routes keep paths as parent pointers instead of copying them
into every label.
- Benchmark suite (1k/10k/100k edges) with a CI speed gate.

0.6.0 - QGIS no longer freezes:
- Route calculation, the OD matrix, OpenStreetMap downloads and the
DEM download run in the background with progress and a cancel button
in the QGIS task bar.
- DEM download budget: large extents use a coarser grid (the real cell
size is shown in the layer name) and ask before many requests or when
a DEM layer is already selected.
- Processing algorithms can be cancelled during the OpenStreetMap
download.
- The dock remembers profiles, weights and playback settings between
sessions; layer choices are saved in the project.
- Scenarios: save points, profiles, weights and results to a JSON
file, load them later and compare the new routes with the saved run.

0.5.0 - Correct routes for every profile:
- Pedestrians may walk against one-way streets; cyclists only where
oneway:bicycle=no; vehicles never.
- Wheelchair and stroller routes never use slopes above 8.33 percent /
10 percent (previously only penalised).
- Pareto routes: admissible time bound from each profile's real top
speed, correct epsilon dominance, and a warning when the search is cut
short.
- Nodes without elevation take their neighbours' height instead of 0
m; DEM slopes are measured over at least 10 m, so DEM noise on short
segments no longer blocks routes.
- Vehicles respect posted speed limits (maxspeed) in cost and travel
time.
- GPS map matching: metric projection, nearest candidates and network
distances between candidates.
- Alternative routes penalise the primary route instead of forbidding
it, so they also work across single bridges.
- Overpass and Open-Elevation failures now show their real cause; the
local viewer server no longer exposes the route to other web pages;
QGIS 4 (Qt6) QAction import.

0.4.1 - Repository moved to GitHub:
- The repository and issue tracker are now on GitHub
(github.com/YusufEminoglu/zero2route3d); the user manual stays at
geophilo.com/zero2route3d.
- Clearer plugin description.

0.4.0 - Profile-Aware Routing & Network QA:
- Added modal access filtering for pedestrians, bicycles and motor
vehicles using OSM-style tags and road-class defaults.
- Added Routing Network Readiness Audit as the fifteenth Processing
algorithm.
- Added bounded network snapping, route diagnostics, weak-component
topology fixes, real convex-hull isochrone area, and projected-center
CRS correction.

0.3.0 - Official QGIS Hub Release & UX Urban Mobility Evolution:
- Transitioned out of experimental status for official QGIS Plugin Hub
publication.
- Enhanced metadata, shortest path descriptions, and added formal
research acknowledgment for Transform Transport inclusive mobility
inspiration.

0.2.9 - Full Map Extent DEM & -5m Relative Skirt Extrusion:
- Query Open-Elevation DEM for the full map canvas extent and
normalized Web 3D terrain skirts to scene minimum elevation with -5m
base plinth.

0.2.8 - Point A & Point B 3D Billboard Text Sizing:
- Dynamically measured text width and scaled the pill textbox
background and sprite aspect ratio so that "Point A (Origin)" and
"Point B (Destination)" fit with comfortable margins.

0.2.7 - Rollback to Verified Web Basemap Milestone:
- Reverted Web 3D studio and codebase back to v0.2.1 basemap milestone
while preserving updated transparent 3D diorama brand icons.

0.2.1 - Web Basemap Coverage & Geolocator A/B Pin Enhancements:
- Resolved Web 3D basemap tile cutoff by dynamically choosing optimal
zoom levels and loading all bounding tiles without artificial
truncation.
- Added lettered A/B geolocator pins and billboard badges in WebGL 3D,
and composite font marker symbology and halo labeling in QGIS.

0.2.0 - Correctness and honesty release:
- Removed fabricated data: the NDVI, LST and NDBI rasters labelled as
Copernicus Sentinel-2 products were generated from a hash of the pixel
indices and fed into the routing cost; the 3D studio displayed a
built-in demo route as if it were real; trees were placed
procedurally; four algorithms substituted a hard-coded line in Izmir
when input geometry was missing.
- Missing elevation, heat and greenery data are now reported as absent
instead of being replaced by 0.0, 0.5 and 0.4, which made a network
with no DEM look flat and fully barrier-free compliant.
- Corrected the Minetti metabolic cost equation, which overstated
walking energy roughly fivefold.
- Fixed field construction that raised TypeError on QGIS 4, so every
algorithm producing a layer failed there before writing a feature.
- Added coordinate reprojection throughout: projected inputs were
being
consumed as WGS84 degrees.
- Fixed the isochrone profile list, which mapped Passenger Car to a
mountain bike and left six profiles unreachable.
- Fixed the accessibility, walkability, cost surface, DXF, HTML and
solar algorithms, each of which crashed, produced nothing, or scored
against invented inputs.
- The standalone HTML export rendered a blank page for every user.
- Processing outputs now carry symbology, field aliases and metadata.
- Closing the dock no longer deletes the route layers you just added.
- Restored the complete GPL-2 licence text and corrected the
documented
algorithm identifiers, 11 of which were wrong.

0.1.0 - Initial release:
- Interactive card-based QGIS Dock with adaptive dark/light styling.
- 15 mobility profiles across pedestrian, micromobility and vehicle
