Apple Released iTunes 8.1 today (v8.0.2 was the previous version). Among the new features are its ability to handle larger libraries more speedily, iTunes Plus (256kbps AAC) importing via CD, and Genius playlists that will scour for video media.
I know of at least one AppleScript enhancement. A track's played date and skipped date properties can now be wiped by setting either to 0 (zero) or missing value. Before, you could never set these properties to anything but a date. While you could set played count and skipped count to 0, the only way to fudge the played or skipped date was to give it a date in the past, like date "January 1, 1970". Now, you can do this:
tell application "iTunes" set sel to selection repeat with aTrack in sel tell aTrack set played date to missing value set played count to 0 -- and/or set skipped date to missing value set skipped count to 0 end tell end repeat end tell
I'll have a look for any other changes.
