+### 2025-09-22 Update tooltip colors
+
+We've updated the tooltip colors to use the foreground color for the background and the background color for the foreground.
+
+Replace `bg-primary text-primary-foreground` with `bg-foreground text-background` for both `<TooltipContent />` and `<TooltipArrow />`.
