Today, Apple released a preview of the latest update to iOS. After reaching version 8.4 with the last version, it seems like Apple is trending toward more incremental updates than in the past. It is nice to see them moving in this direction, unlike in some older releases where essentially only bugfixes were released between major versions.
Some interesting new features in this version, including a night mode that is similar to flux and multi-user mode for education. The education-specific features for iPad seem to signal to me that there will be a new iPad Air released alongside this update in the spring, as rumors have been suggested. Apple will want to market this new education features with a new iPad, and the iPad Pro is simply too expensive (and possibly too large) for education markets.
