 - [Backup] Implement file cache for listing the backups of a VM (PR [#6220](https://github.com/vatesfr/xen-orchestra/pull/6220))
 - [Backup] Add setting `backups.metadata.defaultSettings.unconditionalSnapshot` in `xo-server`'s configuration file to force a snapshot even when not required by the backup, this is useful to avoid locking the VM halted during the backup (PR [#6221](https://github.com/vatesfr/xen-orchestra/pull/6221))
 - [XO Web] Add ability to configure a default filter for Storage [#6236](https://github.com/vatesfr/xen-orchestra/issues/6236) (PR [#6237](https://github.com/vatesfr/xen-orchestra/pull/6237))
+- [Backup] VMs with USB Pass-through devices are now supported! The advanced _Offline Snapshot Mode_ setting must be enabled. For Full Backup or Disaster Recovery jobs, Rolling Snapshot needs to be anabled as well. (PR [#6239](https://github.com/vatesfr/xen-orchestra/pull/6239))
