It says "the youtube flash API was officially deprecated on Jan 27, 2015"?

what does this mean. it appears on my youtube channel and its never appeared before. i clicked on it and it brings me to the terms and conditions and i dont understand what they mean. do they just want to tell you that their just updating how the videos are played or is it something i did. like did i download the one thing?
