0.6.1 - FETE can now optionally output the individual least-cost paths
as a line layer (one feature per point pair, with from_id/to_id/cost),
alongside the traversal-frequency raster. The paths were already
computed internally; they are now exposed via an optional output. No
change to the raster result.
0.6.0 - The pure numpy/scipy core is now also published as the
`itinera` PyPI library (pip install itinera), built single-source from
core/ via hatchling. No change to the QGIS plugin itself.
0.5.9 - Dev tooling: flake8 is now a CI check (max-line-length 88);
excluded maintainer/dev-only files (CLAUDE.md, setup.cfg, pytest.ini,
requirements-dev.txt) from the packaged zip. No runtime change.
0.5.8 - QGIS 4 / Qt6 runtime fixes: the settings dialog crashed on
QDialogButtonBox.Ok (now scoped StandardButton), and the LCP output
used QVariant.Int which PyQt6 removed (now QMetaType on Qt6, QVariant
on Qt5). Verified on QGIS 3.28 and 4.0.
0.5.7 - Code hygiene: removed unused imports (flake8 F401) and added a
setup.cfg ignoring W503/W504. No behaviour change.
0.5.6 - Declared QGIS 4 compatibility via qgisMaximumVersion=4.99
(without it QGIS assumed a 3.99 maximum and marked the plugin
incompatible on QGIS 4). Verified loading on QGIS 4.0.
0.5.5 - Documentation: added QGIS 3.28+/4.0 and Qt5/Qt6 compatibility
badges to the README.
0.5.4 - QGIS 4 / Qt6 compatibility: the settings dialog used exec_(),
which PyQt6 removed; switched to exec() (works on QGIS 3 and 4). No
other changes.
0.5.3 - The "Interactive LCP settings…" button now has its own gear
icon, distinct from the path icon of the LCP tool button.
0.5.2 - Replaced the blank placeholder plugin icon with a real,
visible one, so the two interactive-tool buttons are findable on the
Plugins toolbar. Clarified in the docs where those buttons live.
0.5.1 - Documentation only: README status badges, future-directions
wording, and removal of the internal publishing guide from the README
and the packaged zip. No code changes.
0.5.0 - New "Resample DEM (block mean)" algorithm and a memory
pre-flight warning for large DEMs; stochastic_lcp guards against
n_iter < 1; added a user manual (docs/MANUAL.md) and verified
references (docs/REFERENCES.md, references.bib). Corrected stochastic
citation to Lewis 2021.
0.4.0 - Interactive LCP tool is now configurable: an "Interactive LCP
settings…" toolbar/menu action picks the cost function and
neighbourhood (parity with the Processing algorithms); the graph cache
rebuilds only when settings change.
0.3.0 - New Stochastic least-cost path (Lewis 2023): N Monte-Carlo
realisations with spatially-correlated DEM error (RMSE-scaled) and/or
random edge dropping, accumulating a probabilistic corridor in [0,1].
Seed for reproducibility; supports the barrier/multiplier raster.
0.2.2 - Fix: xy_to_rowcol now floors instead of truncating, so points
just west/north of the raster are correctly out of bounds (not wrongly
snapped to row/col 0).
0.2.1 - Fixes: point layers are reprojected to the DEM CRS before cell
lookup (algorithms + map tool); barrier/friction rasters are validated
against the DEM CRS and geotransform (not just pixel count);
rotated/non-square rasters are rejected with a clear error. Documented
PDI limitations.
0.2.0 - Optional barrier / multiplier raster on the slope-based
algorithms (slope cost surface, LCP, LCC, FETE): edge cost is scaled
by the mean of the two cells' values (>1 discourages, <1 prefers, e.g.
known roads); NoData or <=0 cells are impassable (cliffs, deep wadis).
0.1.0 - Initial release: anisotropic LCP, LCC corridor, FETE, PDI
validation, slope & friction cost surfaces, interactive two-click LCP
map tool. Pure numpy/scipy/GDAL (no external pip dependencies).
