TPM-backed full-disk encryption and expanded memory-safe components are the headline security upgrades for 26.04 LTS.
Livepatch support now extends to Arm systems, enabling live kernel patching without reboots on Arm servers.
New application permission controls add a privilege management layer to desktop and server installs.

Nine official flavors including Kubuntu, Xubuntu, and Ubuntu Studio ship simultaneously with the main release.
Hacker News Comment Review
Long-timers praise OOB hardware support and production reliability, but Snap friction and perceived loss of community spirit are pushing some toward Debian as a first recommendation.
Rust coreutils and sudo-rs inclusion draws pointed commentary: fine print on the rewrite scope is surfaced, and at least one commenter frames their continued presence as likely intentional rather than an oversight.
Practical UX regressions reported: middle-click paste is broken, and full-screen password prompts during encrypted volume unlocks block password manager access entirely – a workflow gap for the new FDE feature.
Notable Comments
