 ## Changelog
 
+### v1.2.4
+
+**Bug fixes**
+- Grid status dot restored — green (online) / red (offline) indicator next to the grid label, reads from `grid_status` entity.
+- Fixed copyright header to match MIT license.
+- Tooltip time calculation corrected (was rounding to minutes, now uses fractional hours for accurate timestamps).
+- History loading guard: `_loadHistory` now checks `this._h` exists before proceeding.
+
+**Visual improvements**
+- Smooth icon fade transitions (0.8 s) when power goes on/off — icons and values no longer snap instantly to dim/bright.
+- Flow snake lines fade in/out smoothly instead of appearing/disappearing instantly.
+- All flow animations synchronized — single shared speed based on the highest active power, all lines pulse in phase.
+- Removed animation delay staggering for cleaner coordinated flow.
+
+**Performance**
+- Sparkline max values cached on history load — tooltips no longer recalculate `Math.max(...data)` on every mousemove.
+- `downsample` extracted to class method — no longer recreated as a closure on every history refresh.
