XCP-ng 8.3 LTS: Refreshed Installation ISOs

Update Aug 14, 2026

We are releasing updated installation images ("ISOs") that include installer improvements and all updates published since the previous release. These are not a new version of XCP-ng, but simply installation media containing most updates available to date. An up-to-date XCP-ng server already includes all updates contained in this ISO.
