+## Highlights of v6.2.1
+
+- **BUG FIX**: Fixed `findCurrentPriceIndex()` to return the correct current interval.
+- Problem: At 17:57, it returned index for 18:00 instead of 17:45, causing display to show hour 18 instead of hour 17.
+- Fix: Now calculates next 15-minute boundary and finds the last entry before that boundary.
