 ## Version Highlights
 
+### v6.2.3 - State-based display refresh logic  (critical fix of v6.2.2 update)
+- Problem: Screen would occasionally fail to update if the ESP32 was busy (fetching data or reconnecting WiFi) during the exact 00/15/30/45 minute mark.
+- Fix: Switched from "Event-Based" (refresh only AT minute X) to "State-Based" (refresh IF current time != last refresh time). This ensures the screen updates immediately even if the device was busy during the transition.
+
 ### v6.2.2 - Display Blank Lines Issue Fix  (critical fix of v6.2.1 update)
   - Problem: Sometimes rows 0 and 1 (current 15-min prices and current hour) were blank.
   - Cause: The "hour suppression" logic was hiding the current hour unexpectedly.
