Canonical has released Ubuntu Core 26, a new long-term support (LTS) version of its immutable, snap-based OS. Among the changes Ubuntu Core 26 brings is smaller over-the-air updates, with download sizes reduced by up to 90% for most snaps thanks to a new snap-delta format. Updates to the Core base snaps specifically drop from 16 MB to 1.5 MB. Installation times are faster as the initramfs-based installer skips redundant reboots during provisioning. Core 26 also enables live kernel patching on ARM64 devices so that critical and high vulnerability kernel security fixes are applied without the need for a device reboot.
