Yes so recently I upgraded my xbox media centre to a november cvs version and found some interesting new features. The biggest change comes in the way of apple itunes support. Using the daap which is used by itunes 4.x, xbmc is able to not only play everything in the library but also all the different playlists. Which I have to say is pretty awesome and has prompted me into downloading itunes on to my tabletpc. If only winamp had support for this too, i would consider switching because itunes is a beast on cpu usage and does not have the plugin support like winamp. Anyway some more screen shots are here and here.
Some other interesting things have also been better intergrated and updated. The great xlink kai client has been updated so now you can type in a chat room using the onscreen keyboard or if your like me, you can use an usb adapter and a real keyboard. So pretty much now the xbmc xlink client is equal to the win32 client. You still need to run the kai engine on a pc or another device but hey you cant have it all.
Like the daap:// protocal there is now a shoutcast:// protocal too which basiclly goes to shoutcast.com and cache's the top 500 shoutcast broadcasts. Another screenshot at 500. Shoutcast being intergrated into xbmc is great and I'm hoping to see more intergration with some of the new scripts poping up. Oh by the way its good to see someone else in the bloggerosphere is keeping up with xbmc. Oh by the way we play here
