iTunes 9.1 Released with Changes
Apple has released iTunes 9.1 just in time for your iPad's arrival on Saturday.
Looks like AppleScript Application Bundles are still not displaying in the iTunes Script menu. I'm wondering now if this is permanent. (They still display in the system-wide Script Menu when placed in (or aliased to) your ~/Library/Scripts/Applications/iTunes/ folder.)
The "Audiobooks" master library is now "Books" and its special kind is changed from Audiobooks to Books. AppleScripts that use the old Audiobooks special kind will need to be updated to use Books in iTunes 9.1 and better. However, it looks like your audiobook files will remain in a "Audiobooks" folder for those of us using iTunes Media organization. Presumably, eBooks will go in a separate folder--"Books"? "eBooks"? "iBooks"? Our first eBook download for the iPad and eventual iTunes sync will tell the tale.
So far, this is the only change I've seen. More as it develops
[UPDATE: After a re-start, AppleScript app bundles were back in the Script menu!]
