Release Notes

  • Last updated on

Important: Please Read Before Upgrading

Make a backup first. Before installing any firmware version, back up your configuration and read all release notes that apply to versions more recent than the one currently running on your system. 

Do not manually reboot your system at any time during an upgrade, unless otherwise instructed by Barracuda Networks Technical Support. The upgrade process typically takes only a few minutes after the upgrade is applied. If the process takes longer, please contact Technical Support for further assistance.

Firmware Version 16.0

Important: Please read the following before upgrading to version 16.0:

  • When upgrading the firmware from version 15.x version to 16.0 or higher, the Web Categorization Service (WCS) version is updated from version 2.x to 3.x (see Web Use Categories). All the existing Barracuda Web Security Gateway policies, Exceptions, Content Filters and the Barracuda Web Security Gateway web interface are updated to reflect WCS 3.x categories. Because mapping of WCS 2.x categories to WCS 3.x categories is not exactly 1:1, some policies will shift. Some categories will appear more granular in the latest version of WCS 3.x on firmware 16.0.

  • Reporting data is cleared.
  • The dashboard data is reset.

  • All data is cleared and starts from scratch after upgrading to 16.0.

  • Web Logs are cleared.  

  • If you revert back to firmware version 15.0, your data and configuration will be what it was before updating to version 16.0, whether you were running WCS 2.x or 3.x on version 15.0 before you updated to 16.0.
  • The Barracuda Chromebook Security Extension is not currently supported by the Early Release of firmware version 16.0. The extension will be supported in the General Release of the firmware.
