The examine window was an easy change this time around, as folks have mentioned.
Dolby hasn't posted compares in a while unfortunately. Nowadays I just use https://www.diffchecker.com/
or something similar. For best results sometimes you've got to jigger with the whitespace to keep it from presenting a ton of changes.
Another easy way to compare major changes / additions is to open the current and the old version (or live and beta) in your text editor of choice side by side and scroll down both. It's pretty easy to see when line numbers start getting off etc.
