The KaZaa Media Desktop is a second-generation peer-to-peer file-sharing service with which you can search and download media files from other KaZaa users. You can also organize and play/view your media files through an integrated media jukebox, publish your own work, reach an audience, and communicate with other KaZaa users.
No noted changes on the Kazaa website.
