Version 0.17.1 (2026-10-08) - Updated comparison module
Version 0.17.0 (2026-10-05) - Updated junction matrix calculation,
highlighting selected legs.
Version 0.16.10 (2026-10-02)- Powered-model rays now span +/- 6 sigma
with 1000 rays (was 4 sigma / 500), stated in the report and marked by
ticks on the tangent line.
Version 0.16.9 (2026-10-01) - New Category I start zone setting
(Causation factors, default on 10 percent): in-lane hits right after
the origin waypoint are ignored. Result layers, the results Markdown
and the View breakdown name legs as in the route table (LEG_1_2_b East
going) instead of leg_9_0.
Version 0.16.8 (2026-09-28) - Compare tab can add difference layers (B
- A) showing where on the map the accident probability changed between
two runs.
Version 0.16.7 (2026-09-25) - Added distribution on the map,
auto-pop-up of junction matrix after fetching AIS data
Version 0.16.6 (2026-09-23) - South LineEdit box is now visible for
the drift rose.
Version 0.16.5 (2026-09-23) - Adding the feature to supress and move
traffic from one leg to others.
Version 0.16.4 (2026-09-22) - Added a custom ship type mapping (IMO /
MMSI -> category) kept as a table in the AIS database and managed from
Settings > Ship type mapping (CSV import/export); the external vessel
lookup ship type column is now honoured.
Version 0.16.3 (2026-09-21) - Added a one-at-a-time sensitivity
analysis (Run Analysis tab) that ranks the inputs by their effect on
the accident totals.
Version 0.16.2 (2026-09-21) - Split the result presentation of powered
accidents. IWRAP export now writes each direction's position check
interval (ai) and expresses ai = 0 as a zero leg extension; import
maps both back.
Version 0.16.1 (2026-09-18) - AIS-derived junction matrices now
survive file load and leg edits, and a single-leg Update AIS skips the
junction pass when every junction already has AIS evidence.
Version 0.16.0 (2026-09-17) - Legs now hang on shared waypoints:
dragging a junction moves every leg on it and clicks snap to existing
nodes. Vertex edits are captured after Stop route / edit-mode toggles
(they were lost before). New routes number their legs from 1 without
touching existing legs. A project saved before its first AIS pass
loads again, and schema errors are shown instead of silently ignored.
AIS-derived junction matrices now survive file load and leg edits, and
a single-leg Update AIS skips the junction pass when every junction
already has AIS evidence.
Version 0.15.1 (2026-09-08) - Minor bugs fixes and added new ways of
presenting the results
Version 0.15.0 (2026-09-03) - Powered grounding and allision now
include IWRAP Category I (obstacle inside the lane) next to the
Category II missed-turn model, with separate Cat I causation factors,
IWRAP XML mapping and report split.
Version 0.14.3 (2026-09-03) - Made it possible to move the tangent
along the leg and fix saving and copying traffic.
Version 0.14.2 (2026-09-02) - Improved result presentation and compare
presentation.
Version 0.14.1 (2026-09-02) - Now added tangent layer in QGIS when
loading model
Version 0.14.0 (2026-08-28) - Corrected the crossing and bend
collision formulas IWRAP XML export now writes the project's own
causation factors, instead of hardcoded constants Documentation
reviewed end to end.
Version 0.13.5 (2026-08-19) - Bugfixes and improved documentation
Version 0.13.4 (2026-08-18) - Bugfixes and improved documentation
Version 0.13.3 (2026-08-17) - Improved speed while handling of depth
data.
Version 0.13.2 (2026-08-13) - Minor bugfixes and flake8 fixes
Version 0.13.1 (2026-07-07) - Now splits overlapping legs
Version 0.13.0 (2026-07-06) - Some minor bug fixes.
Version 0.12.3 (2026-06-18) - Minor bugfix.
Version 0.12.2 (2026-06-18) - Updated documentation, some
visualization issues and other details.
Version 0.12.1 (2026-06-17) - Added notifiers in QGIS message bar
Version 0.12.0 (2026-06-01) - Added the possibility to scale the AIS
traffic
Version 0.11.2 (2026-05-19) - Updated documentation and help section,
renamed the LEG to reflect the routes.
Version 0.11.1 - Minor code comments updates and some checks regarding
junctions.
Version 0.11.0 - Added consequences to calculate the risk of maritime
accidents
Version 0.10.1 - Fixed some minor bugs
Version 0.10.0 - Added ingestion of AIS data
Version 0.9.3 - Improved visualization of the result and improved the
documentation

Version 0.9.0 - Major rework of the drifting calculation and updated
documentation
Version 0.4.1 - Refactored the run_calculation and updated
documentation
