Apple has released iTunes v8.0.2. As of this writing it is only available via Software Update; I prefer to download the installer from the download page, so I’ll wait a bit. According to the release notes, iTunes 8.0.2:
- Addresses a quality issue creating MP3s on some computers.
- Fixes a connectivity issue with the iTunes Store when using some Internet proxies with Mac OS X.
- Improves accessibility with VoiceOver.
More info when and if available.
