iTunes 10.0.1 official with Ping sidebar, fixes
Apple overnight released iTunes 10.0.1 (84MB). The patch adds the previously hinted at Ping sidebar and gives listeners a way of tracking artists and friends while still looking at the iTunes library. It's also now possible to Like or Post from the library instead of just the iTunes Store.
The release otherwise emphasizes fixes. iTunes 10.0.1 fixes an issue that changed video quality depending on whether or not the on-screen controls were up; it similarly patches a crash bug which would close iTunes while interacting with album art in a separate window. Apple has resolved a flaw that would sometimes show the library and playlists as empty. Third-party support rounds out the updates and sees improved performance with unofficial visualizers as well as better compatibility with third-party iTunes sources.
The update is available for both Macs as well as 32-bit and 64-bit Windows users.
