Update Means that Something about the Current CARD has Changed..
Could be a new Tag was added, or Could be a Bad Animation was fixed.. Or could be a name change..
If you Do not have any issues with the current card as it is, No Need to Update it..
Many of the cards are now Being Processed with a New Encoder, so this means all the animation files are New, but the same resolution.
Example: All New 720p encoded files for a 720p card.
Cards that have a new Resolution will have the RESOLUTION sticker.
so Update sticker means different than Resolution..
