We're proud to present the next iteration of our Proxmox Virtual Environment platform. This new version 9.1 is the first point release since our major update and is dedicated to refinement.
This release is based on Debian 13.2 "Trixie" but we're using the newer Linux kernel 6.17.2 as new stable default. In addition to the main system enhancements, this update incorporates the latest versions of core technologies, including QEMU 10.1.2, LXC 6.0.5, ZFS 2.3.4, and Ceph Squid 19.2.3, all fully tested and integrated.
Please review the key highlights below, and thank you, as always, for your invaluable support.
