Changeover to API 0.4 on Saturday 05 May 2007 - If you get Sunday's josm-latest.jar from the link below, you will not need not change your preferecnes file - API 0.4 is the default now. Note that you cannot read OSM files saved with old versions unless you manually change the <osm version="0.3"> into <osm version="0.4"> at the top of the file. Some issues with 0.4 remain, notably how to handle the new fields provided by the API and how to support reading 0.3 files; expect these to be dealt with shortly.
