 # Changelog
 
+## 0.14.24
+
+- Public Custom Charts fetch chart metadata before language assets, so a chart loads only its selected language pack; missing chart IDs fall back to English.
+- Public Custom Charts support pinch-to-zoom, one-finger horizontal panning while zoomed and per-metric visibility toggles through the legend.
+- Missing public chart IDs now return `chart id not found`, the favicon is no longer redundantly pre-cached, and invalid Access Tokens show an inline authentication error.
+
 ## 0.14.23
 
 - Code cleanup and small UX changes.
