This version comes with several new features, support for Secure Boot, a Software-defined Network stack, a new flexible notification system, and many further enhancements and bug fixes. Proxmox VE 8.1 is based on Debian 12.2 (“Bookworm”), but uses a newer Linux kernel 6.5 as stable default, and includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 8.
