iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
iPod Classic and Nano Update 1.0.2
The new update comes without any description, but a couple of early reports:
- Improved Cover Flow
- Faster menu navigation
- Compilation Album Art displayed only once in Cover Flow
- Video Out Fix
Overall, it appears to address many of the performance concerns that many had when the Classic iPod first came out.
