Released in late November 2012, Apple today updated iTunes to version 11.0.3. The new version, available through the Mac App Store's Software Update panel, brings a redesigned MiniPlayer, an improved songs view, support for multi-disc albums, and performance improvements.
The biggest change of iTunes 11.0.3 is the new MiniPlayer. Sporting a progress bar, the MiniPlayer now also comes with a larger artwork view that can be activated by clicking on the artwork thumbnail in the bottom left corner. The new artwork view will turn the MiniPlayer into a widget reminiscent of desktop music controllers like Bowtie and CoverSutra, with the usual controls to adjust volume, hide/view Up Next, and access an additional contextual menu. In the image above, you can see a composited screenshot of the new MiniPlayer views.
iTunes 11.0.3 is available now on Software Update and through Apple's website.
