Alike v7.1.0 build 9167
Released: 5/4/2023
This is a major release. All users are encouraged to update.
Please Note
- Q-Hybrid, Physical, and Hyper-V agents must be reinstalled. Use this link to for the latest agent binary.

- CBT jobs will likely need to rebaseline after you upgrade. Prepare for longer-than-usual backup times for the first backup after upgrade

- Resolves all active issues with Hyper-V Backup
- Streamlines and improves Xen CBT codepath, making it more scalable and eliminating need for temporary disk
- Introduces new approach to ABD and Q-Hybrid replication (non-CBT) that leverages proven Quadric backup pathway
- Improves support of Linux filesysystems in file-level restore (specifically, support for disks without any partition table)
