In this release you should notice reduced audio latency, i.e. the delay between changing something like the frequency or mode and the resulting change in audio. This is especially true for local connections. A connection where the Kiwi and computer running the browser are on the same local subnet. The audio buffering is reduced even more for this case.
To switch back to the previous behavior click on the "Snd" button (above the "More" button) so it shows white instead of green and then reload the page. This setting is saved in a cookie across reloads like some of the other buttons are.
