Released yesterday for download.
They've cleaned up the interface and you get some nice new views:
http://www.apple.com/uk/itunes/overview/ A few other improvements:
1) Your iPod settings are now easy to get to by clicking on the iPod in the device list on the left
2) iTunes now automatically recognises and thus supports gapless playback of albums designed that way. For example Dark Side of the Moon by Pink Floyd. If you have already ripped a CD like that to your hard drive, no problem, iTuens will analyse all your music and work out which ones should be played gapless, you need do nothing.
3) You can now sync any purchased music to other iTunes registered computers via your iPod. ie, if you have a computer at home and download a track from the iTuens store and want to listen to it at work you previously had to find it on your hard drive and copy it to a disc or whatever, take it to work and add it to iTunes there. Now, once it syncs that song to your iPod simply take the iPod to work and it will automatically copy the song to your work machine (assumng your work machine is authorised with the iTunes store).
4) Downloaded videos are now in 640x480 instead of 320x240 so they look sharper.
5) If the songs you have in your library were ripped from CD but you thus don't have the album artwork iTunes will download it automatically from the iTunes store for free (if the iTunes store carries the album in question) which saves you a job of going to amazon.com and swiping their album art...
Oh and they now sell movies (but to the USA only, we have to wait until Q1 2007).
They also announced upgrades to the video iPod as well as a price drop, and NEW iPod Nanos and an even smaller, cheaper, iPod Shuffle.
