 # Changelog
 
+## 1.1.0
+
+He gets a life.
+
+- **Weather**: `denWeather('rain'|'snow'|'clear')`. Rain sends him to shelter under
+  the nearest POI, where he sulks until it passes. Snow delights him and makes his
+  prints linger 3x longer.
+- **Treats**: `denTreat(x, y)` or the `treat` shell command. He sprints for it, eats
+  it, and it counts toward trust. Hunger builds over a session and he'll say so.
+- **Scroll reaction**: he's carried by the page when you scroll, scrambles back to
+  your cursor, and arrives winded.
+- **Personality drift**: idle mutterings change based on hunger, and on whether a
+  returning visitor has ever actually touched him.
+- Trust is now pets + treats throughout (gift threshold, resting behaviour, emotes).
+
 ## 1.0.0
