Apple on Friday released iTunes 12.3.2. The update is of particular interest to classical music listeners. According to the release notes:
This update allows you to see works, composers, and performers while browsing Classical music in the Apple Music catalog.
Even if you don’t listen to classical music, you’ll want to install the update anyway, since it also includes “stability and performance improvements.”
To update iTunes, launch the App Store app in your Mac’s Application folder. Click on Updates, and iTunes 12.3.2 should appear after the App Store polls Apple’s servers.
