Sorry. :-) It's just been a while since the last release and I didn't want you guys thinking nothing was happening with the software.
tandemrx: I did not add a preference for the "confirm on manual round changes". I've had it in my development version for a while now, and believe me, I do a lot of the same thing you do. Honestly it hasn't been much of a hassle, especially since you can confirm with just another quick keystroke. I added this as a "better safe than sorry" feature. Manually advancing (or retreating?) the round is undo-able in the sense that you can go right back to the previous (or next) round, but if no one was paying attention to the clock, you can't go back to the correct time left in that round. And even though it isn't drastic, it could be painful if someone accidentally presses the wrong hotkey (or a button on the screen) and advances the round. Just better to have a confirmation.
