Search servers now output the new format

http://search.musicbrainz.org/ws/2/release/?query=fred&fmt=jsonnew

but webservice interface needs to support setting fmt=json and translating it to jsonnew for search server ( we cannot use fmt=json because that returns the internal json format currently used by the website)

i.e
http://musicbrainz.org/ws/2/release/?query=fred&fmt=json

goes to

http://search.musicbrainz.org/ws/2/release/?query=fred&fmt=jsonnew
