The default /boot partition size has been increased from 1 GiB to 2 GiB to accommodate larger initramfs images and firmware blobs, ensuring sufficient space for future kernel updates. Existing smaller partitions can still be reused, or the size can be reduced manually if needed.

The greenboot package is now built from greenboot-rs upstream project. The previously existing greenboot health check framework was enhanced as greenboot-rs, a reimplementation designed for improved maintainability and supportability. The new version is fully compatible with existing greenboot functionality and custom health checks. As a result, system rollbacks during upgrades are more robust.
