A side-by-side editorial comparison of Glances and NetObserv — release velocity, themes, recent moves, and the top alternatives to consider.
Glances 4.5.9 closes out the 4.x line as a 5.0 beta opens for testing.
Glances 4.5.9 replaces the python-jose library, which carried a CVE, with PyJWT and updates every dependency. The notes say it is the last 4.x release and point users to a Glances 5.0.0 beta on Test PyPI and a dev Docker image. Most 4.5 releases this year were security and correctness fixes.
NetObserv hit 2.0 without breaking changes, then started renaming its metrics.
NetObserv's operator reached 2.0.0 in September, labelled entirely non-breaking: BGP ASN enrichment through FRRConfiguration CRDs, DNS names in metrics, DNS port configuration in the FlowCollector API, stricter RBAC and network policies for the operator itself, and TLS settings taken from the OpenShift API server. 2.0.1 was fixes and dependency bumps. 2.0.2 fixes ASN labels and IPSec metrics, captures OpenSSL socket tuples at event time in the eBPF agent, and renames filtered_flows_total to filtered_packets_total.

After a year of CVE patches and alert correctness work on 4.5, the project is ending the 4.x line and moving to 5.0. The feed does not yet describe what changes in 5.0.
Expect further 5.0 betas and then a 5.0.0 release; whether it changes the plugin model, web UI or API is not visible in these entries.

The 2.0 line adds routing context (BGP ASNs) and DNS identity to flows, which moves the tool from 'which pod talked to which' toward 'which network and service.' The operator's own security posture, with RBAC, network policies and TLS profiles, is getting as much attention as the data. The TLS thread continues inside the eBPF agent, with OpenSSL tracking narrowed to packet mode in 2.0.2.
Expect 2.0.x fixes around the new ASN and TLS enrichment, which both needed corrections in 2.0.2. The metric rename is a signal that dashboards built on older names may need updating in later releases too.
