The changes will be significant; they should not, however, either make it harder to read or turn this blawg into something that it's not. Think of them more like the two-years-into-life-cycle "facelifts" that Detroit used to give passenger cars. It'll be the same engine and transmission under the hood I'm not going hybrid but the interior should be a little more up-to-date. I might even install a built-in cupholder so you've got somewhere to put your coffee before spewing it on the keyboard.
