@@ -40,6 +40,7 @@ changelog.txt uses a syntax similar to RST, with a few special sequences:
 - Core: ``alt`` keydown state is now cleared when DF loses and regains focus, ensuring the ``alt`` modifier state is not stuck on for systems that don't send standard keyup events in response to ``alt-tab`` window manager events
 
 ## Misc Improvements
+- `buildingplan`: now displays which items are attached and which items are still missing for planned buildings
 - `tiletypes-here`, `tiletypes-here-point`: add --cursor and --quiet options to support non-interactive use cases
