So I'm debugging today, and decide I want to see a window of ten lines around the current line of code, and enter "w." I get some strange error about a watch expression. Obviously, I've entered some "add a watch expression" mode I didn't know about and need to get out of it so the w key can regain its normal meaning. I monkey around a bit, finally realize I'm not in any such mode, and the "window" function is now accessed with "v."
It's change, and I don't like it. (Which means at the moment I'm a bit sullen but I trust you people so I know 5.8.0 has a good reason for driving me nuts with debugger changes.)
