Release date: 17 April, 2026
Version: 2.0.376
FastNetMon Advanced 2.0.377 delivers a major refactor of the command line tool and API, making integrations more modern and maintainable. The release also improves IPv6 traffic visibility by fixing an issue that could prevent network traffic from being detected correctly. New operational controls have been added to give administrators more flexibility over traffic calculation and system permissions. In addition, several outdated configuration options have been deprecated or removed as part of ongoing efforts to simplify setup and reduce legacy complexity.
