Proxmox 8.3 "Virtual Environment"

This version is based on Debian 12.8 (Bookworm), but uses the Linux kernel 6.8.12-4 as stable default, and allows for opt-in use of kernel 6.11. The software includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 9.0.2, LXC 6.0.0 , and ZFS 2.2.6 (with compatibility patches for Kernel 6.11). Alignment of the Software-Defined Networking (SDN) stack with the firewall: The SDN technology allows users to create virtual zones and networks (VNets), enabling them to effectively manage and control complex networking configurations and multitenancy setups via the web interface of Proxmox VE. The SDN stack is now more closely integrated with the firewall, with the ability to automatically generate IP sets for VNets and virtual guests managed by the IP address management plugin. Referencing IP sets in the firewall rules simplifies their creation and maintenance. In addition, the opt-in firewall based on nftables now has the capability to filter forwarded network traffic at the host and at the virtual network (VNet) level. For example, this can be used to restrict SNAT traffic or traffic flowing from one Simple Zone to another. Official announcement Download Proxmox
