Release Notes - Barracuda NAC/VPN Client 5.3 for Windows

  • Last updated on

Barracuda NAC 5.3 for Windows

This is a 5.3.x Feature Release containing several architectural changes. Before starting a production rollout, please consider whether a Maintenance Release or a Feature Release is the best version for your requirements balanced against risk. We always recommend that you test the client in your own environment and then do a staged iterative rollout in order to quickly identify any issues running the client in your specific environment.

Before installing the new software version, back up your configuration and read all of the release notes that apply to the versions that are more current than the version that is running on your system.

Do not manually reboot your system at any time while the update is in process, unless otherwise instructed by Barracuda Networks Technical Support.
