iTunes 7.3 unexpectedly, shockingly available

Since I installed this update I keep getting the following error: "The iTunes Library file cannot be saved. An unknown error occured (-50)." I only have 10.74 GB available for us on my Macbook at the moment - is that why I'm getting the error?

To some of you having problems with it quitting right after launch:

Make sure you don't have any 3rd party plugins or (especially) visualizers loaded. I know the visualizers have caused that problem for me multiple times when updating iTunes.

Best of luck.

Also added is Coverflow, in podcasts.

"Playlists" now has a collapse icon.

@30 Roman:
The lighter buttons are not a mistake. It's pretty apparent that they've changed them to increase the contrast for their sight-impaired users. I love seeing changes like this.

Rejoice to fixed Coverflow! I've been wanting an update for months since 7 came out.

Problem is being disused on support at apple

There's also a new importing setting for the AAC Encoder: 'Higer Quality (256 kbps)'

@Pete Umm my Bluetooth icon in the menu bar seems to have moved ...

Hold down Command over the and you can drag the bluetooth icon to reorder its position!

There's something very wrong with the buttons at the bottom of new iTunes (shuffle, repeat, etc). They appear to be a shade of gray too light.
Oh and there's a new pane in Preferences to back up iPhones.
