Some of the more interesting points:

• transition from dbus-daemon to dbus-broker
• package-agnostic App Center
• simplified installation experience that dramatically reduces complexity during partitioning and storage configuration
• new onboarding experience that moves personalization and system setup into a dedicated first-boot experience. Rather than asking users to make every decision during installation
• on-device speech-to-text engine integrated as a native desktop input method, providing a foundation for fast, private, and offline voice interaction
