Macworld Senior Contributor Kirk McElhearn lists Ten great AppleScripts for iTunes 10 at Macworld. Thanks!
Apple has released iTunes 10.0.1 which adds some new features to Ping and makes a few fixes. Kirk McElhearn has a good first-look at Macworld.
Re-Locate Selected will re-locate the files of the selected iTunes tracks from their current location to a new user-chosen folder. iTunes will be updated with each track's new location and all of each track's meta-data will be preserved. There's also an option to remove the files from their original location.
A quick fix for the problem of Automator Actions breaking with iTunes 10 is posted at Mac OS X Hints. It is related to the versioning routine I was talking about yesterday and iTunes' version "10.0" string.
Some AppleScripts from this site use a routine that checks for the version of iTunes you are running. Some of the scripts that use these routines are broken under iTunes 10. So when running a script with iTunes 10.0 you may run into a dialog that erroneously reports something like "This script requires iTunes 6.0.2 or better". This is not a bug in iTunes, but a problem with the way the script does the version check. (Long story short: the version number once was a number, but more modern versions of apps use a string. Thus "10.0" is not necessarily greater than "9.2.1" and the routine fails to accommodate this.) You can edit/comment out the version check routine yourself or wait until I get around to fixing the handful or so scripts that are affected. In that case, let me know if you see the error.
Apple released iTunes 10 yesterday, available from the iTunes download page and Software Update (it was about 8 hours between Steve Jobs' announcement and the release). iTunes 10 has a new look, an AirTunes reboot with AirPlay, and the new "Ping" social networking feature. As far as I can tell, current AppleScripts and apps from this site work as well as they always have on iTunes 10. I'll have more compatibility information if necessary after I check around with my iTunes Buddies.
