The other guys listed a bunch -- here are some additional things:

1) download w/ playlist directories
2) download filename with variable replacement (i.e. {title}-{tracknr}-{artist}.mp3)
3) Layered soup playlist (By Artist then By Album)
4) Colorized dirty nodes
5) Search for containers (i.e. find all playlist that CONTAIN matches, rather than the matches themselves -- for finding all the playlists that contain a certain tune)
6) Download w/ Hijack (much faster than Empeg protocol download)
7) Variable replacement playlist directories {genre}/{title}.mp3 (for downloads from the soup)
8) Internationalized sorting + Sort articles in the back ("The Birds" sorts as "Birds, The") -- I don't think Emplode does this? (maybe does i18n sorting)
9) Faster release cycle

Those are the things from the release notes anyway ... I'm sure there are other little things.
