Dashboard widgets now accept lowercase hex color codes and properly handle widget configurations created before version 2.5. After updating to 2.5, some widgets — such as the "Average scatterplot" with specified colors for median, average, or metric — crashed due to validation errors for _FigureRequest.
This fix resolves the issue by correctly processing older widget configurations and accepting hex color codes with lowercase letters. No further user action required.
