Release overview 

Linux for x360Recover Agent 3.5.0 is a feature release. The primary focus of this release is to add support for the latest Red Hat and Debian distributions, as well as address bugs found during support escalations.

Summary of enhancements

• Snapshot driver updated to support Linux kernel 6.5 and 6.7
• Agent installer supports Red Hat Enterprise 9¹
• Agent installer supports Debian 12
• Agent installer supports ElementaryOS 6 and 7
• Agent supports backup and recovery of protected systems virtualized on Xen Server or XCP-ng
• Smart Recovery is enhanced to support Linux Virtualization²

¹Agent for Linux 3.5.0 supports Red Hat Enterprise Linux versions (RHEL) 7, 8, and 9, including Red Hat clone distributions like CentOS, AlmaLinux, Oracle, and Rocky.  

• Due to a Linux kernel compatibility issue, RHEL 9 distributions using XFS filesystems cannot currently be supported by the server backend. 
• The Linux kernel version 5.14 included with RHEL9 creates an XFS file system that cannot be mounted under previous Linux kernel versions. 
• Work is in progress to upgrade x360Recover appliances and vaults to Ubuntu 20.04 LTS, to be released in 2024 Q1, which will enable full support for RHEL9.

² Linux virtualization is hidden under a feature flag in the appliance and vault UI while we evaluate currently supported and unsupported Linux configurations.  Once testing is completed, this feature will be released in the UI.
