Oh, uh, I just updated the currently existing download, as per my usual. I'm not in the habit of making separate downloads unless there's some kind of event attached to the release.
Though, adding a new download would bump the page as far as being on the "Latest downloads" section is concerned, and the total download count might be retained. I guess the only disadvantage to setting a new download to be the "main" download is that the "Download Now" counter would, necessarily, be reset to 0?
*Edit: Overwriting an old download might also mess up Misao voting/nomination as well, but, I don't really know. Nor particularly care.
