Release date: 7 April, 2026
Version: 2.0.376
FastNetMon Advanced 2.0.376 introduces protocol parsing improvements, enhanced flow visibility, and platform lifecycle updates, while continuing to refine analytics and integrations. This release adds PPPoE IPv6 parsing and expanded counter handling for the sFlow plugin, alongside a new option to process counters delivered via sFlow. Flow Spec workflows are improved with richer flow tracking information in notifications and cleaner email output, while remote attack handling gains new integration groundwork and callback propagation. ClickHouse metrics are extended with remote top talker exports, NAT event tracking is improved for NetFlow v9, and parser observability is enhanced with detailed error tracking. The release also upgrades GoBGP to version 4.4.0. Support for Ubuntu 18.04 and 20.04 is now deprecated as these operating systems are no longer under security support; users are strongly advised to upgrade to a supported Ubuntu version to ensure continued security updates and compatibility.
