Base OS

A list of the improvements for the operating system and GUI usability changes that have been introduced in this release.

• Recurring downstream sensor software update schedules can be managed from Central Management Console (CMC).
• In certain cases, such as simultaneous human interventions, multiple concurrent install_update commands might have been issued. This update resolves those cases by implementing a new process to prevent multiple instances of the install_update command from being executed simultaneously. If this new process is actively trying to prevent multiple simultaneous updates while no update is actually in progress, it means the sensor's ability to update has been impacted. In this case, a rebooting of the sensor will disengage this process and will return the sensor's ability to update to a fully functional state.
• CMC users can now manage backup schedules for downstream sensors.
• With Nozomi Networks Operating System (N2OS) 22.4.0, we upgraded the algorithms used for decrypting software licenses, because the ones used before were identified as unsafe. Towards the end of 2024, Nozomi Networks will distribute only licenses encrypted with the new set of algorithms. This means that starting from the end of 2024, all new N2OS software licenses and renewal software licenses will only work with sensors running at least N2OS 23.0.0. Users must upgrade their sensors to N2OS version 23.0.0 or higher to ensure compatibility with new licenses and avoid license renewal issues.
