Red Hat Enterprise Linux 8.1 Released With Kernel Live-Patching Support
Arguably most notable with RHEL 8.1 is that kernel live-patching is now officially supported on RHEL for applying kernel security updates without reboots. This comes after Red Hat for years has worked on Kpatch and the in-kernel live-patching infrastructure.
Red Hat Enterprise Linux 8.1 is also shipping with container-centric SELinux profiles, new Red Hat Enterprise Linux Systems Roles, various hybrid cloud improvements, and other updates.
