 The steady-state routing assumption is appropriate for small basins under intense storms; larger basins where peak attenuation along the channel matters will see biased-high peak Q and biased-high flood depths. If you need full physics, look at [LISFLOOD-FP](https://www.bristol.ac.uk/geography/research/hydrology/models/lisflood/), [HEC-RAS 2D](https://www.hec.usace.army.mil/software/hec-ras/), or [WFlow](https://github.com/Deltares/Wflow.jl).
 
+### What's new in v0.2.1
+
+- New optional module `floodpath.interactive` — ArcSWAT-style outlet picker on a leafmap widget. `pick_outlet(lat, lon)` shows a hillshaded DEM + Strahler-coloured stream network on a Carto Positron basemap; clicks auto-snap downstream to the nearest stream cell, the upstream basin is delineated and overlaid, and the marker is draggable for fine-tuning. Install via `pip install floodpath[interactive]`.
+- New `floodpath.hydrology.snap_to_stream` helper underpins the picker; surfaces outside-DEM-bbox clicks as a clean `ValueError` so callers handle one branch.
+- New end-to-end example notebook at [`examples/pick_outlet.ipynb`](examples/pick_outlet.ipynb), walking the full DEM → flow → streams → outlet → HAND → flood → population → damage chain at Kigali, Rwanda.

 ### What's new in v0.2
 
 - New modules: `floodpath.landuse` (ESA WorldCover + Manning's roughness), `floodpath.soil` (SoilGrids 2.0 + NEH 630 Ch7 hydrologic soil group), `floodpath.precip` (uniform synthetic; pluggable for any user-supplied grid), `floodpath.runoff` (NEH 630 Ch9 SCS Curve Number + Ch10 SCS-CN equation), `floodpath.routing` (steady-state hydrologic + Manning hydraulic closure)
