Specifically, command blocks with delayed ticks will only work if still powered when the command would execute. If a command were delayed to 15s after redstone is activated, and on the 10s mark the redstone signal was removed, it would not go off. In previous versions, so long as the command block received any redstone at all, whether it was for the entire duration or not, the command would still fire.
