SphireOS Release Notes

SphireOS 261.18 (October 2023)

GA: 19th October 2023

What's New

• We added a new feature that allows full agent bypass. This means that when full agent bypass is enabled, SphireOS will not process any Connect application or extension traffic, improving appliance performance.
• We added Intel’s Out-Of-Tree igb driver into SphireOS.

SphireOS 260.13 (July 2023)

GA: 26th July 2023

What's New

• We added a new feature that allows for the inclusion of a group in an On network bypass list. This means that when agent filtering on the network is enabled, and the group device is connected to the school network, SphireOS will filter the device instead of relying on the Agents.
• We made updates to the Prerouting and Postrouting advanced configuration settings. As a result, SphireOS will now dynamically enable these options for an Appliance when necessary, based on your School Manager configuration.
• We updated the default Advanced Configuration values to help streamline the Linewize Appliance build process.
