I recently did an overhaul to the Notice template to allow for the border to be any color as well as making the code more effecient.
Most pages using this template shouldn't see any change, however, the pages that use the Notice template with 2 different colors for the border may have to be updated.
For example, consider the Notice template with a left border of red while the rest of the border is #e6e6e6.
OLD:
To achieve this before now, the template would have had to be used like so:
{{Notice|style = border: 1px #e6e6e6 solid;|border = red}}
NEW:
To achieve this now after the update, the template would need to be used like so:
{{Notice|border = #e6e6e6|left_border = red}}
Take note that the "border" parameter would now need to use the color that was previously specified in the "style" parameter while the "left_border" parameter now uses the color that was previously specified in the "border" parameter.
I apologize for the inconvenience, but until notices that are affected by this breaking change are updated, they will at least continue to display with a border color of whatever is currently specified in their "border" parameter.
