Release date: 27 April, 2026
Version: 2.0.378
FastNetMon Advanced 2.0.378 improves flexible counters by fixing a minor degradation issue in the underlying fcli component. The release also enhances BGP processing with up to 2x faster table loading, additional profiling, and expanded support for standard BGP attributes. ClickHouse integrations have been strengthened with TLS connectivity, improved cloud compatibility, and reliability updates for metrics storage. In addition, new traffic database fields have been introduced to extend packet metadata collection.
