New Jaikoz 4.0 NGS Beta 3 now available that fixes some issues and adds some enhancements to Jaikoz Beta 2.
MusicBrainz NGS is now live, and this beta points to the live server (if you upgrade from beta 2 it will still say http://ngs.musicbrainz.org in preferences but now this actually points to http://www.musicbrainz.org)

This will be the final beta, and expect the Jaikoz 4.0 to be fully released with no more changes on May 19th.
