+
+* Read network data. 
+
+  - Filter national sub-network automatically (with warning) rather than stop on nodes off-boundaries. (#44)
+
+  - Warn (instead of error) if all links are unidirectional. Danger: assuming directionality when in reality the data is non-directional. (#41)
+  
+  - Automatically aggregate volumes for multiple links (with warning,
+  rather than error).
+  
+  - Stricter check consistency of nodes coordinates. Before, we
+  checked (and errored) whether the same node had different
+  coordinates. Check also for the same coordinates havind different
+  nodes. It is likely a typo in the name of a locality, and we don't
+  want to treat them as different nodes.
+  
+* Accept grd/gri files as raster format.
+
+* New vignette: animal mobility file-format cheatsheet (https://umr-astre.pages.mia.inra.fr/mapMCDA/articles/animal_mobility.html).
+
 * shiny interface v2 with several improvements (#8)
 
-* several bugfixes
+* several bug- and doc-fixes
