What is L1centrality?

A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.

L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.

What is oVirt?

A virtualization manager coasting on backports, with releases years apart

oVirt Engine's release feed is sparse and slowing: 4.5.5 in late 2023, 4.5.6 and a pair of 4.5.3.x backports in early 2024, then nothing until 4.5.7 in December 2025. Almost every entry is a list of targeted fixes and backports rather than features — OVF import edge cases, template handling, NVRAM save/restore logic, CA generation as a non-root user, Keycloak group handling. One CVE, CVE-2024-0822, appears in 4.5.6 and its 4.5.3 backport.

A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.

◆ Current state

L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.

◆ Where it's heading

The package has moved from defining measures to operationalizing them. 0.5.0 was the inflection: parallel local computation and list-valued group input both target users running these measures over many vertex sets or large graphs rather than illustrating them on one. The same release renamed weight_transform and eta to edge_weight_transform and vertex_weight, and added an explicit message when a distance matrix is received — the signature of a maintainer fielding the same misuse repeatedly.

◆ Prediction

The last two releases carry no functional change, so the near-term path is maintenance rather than new measures; a 0.6.0 would most likely extend parallelism beyond L1centLOC to the other computationally heavy variants.

◆ Current state

oVirt Engine's release feed is sparse and slowing: 4.5.5 in late 2023, 4.5.6 and a pair of 4.5.3.x backports in early 2024, then nothing until 4.5.7 in December 2025. Almost every entry is a list of targeted fixes and backports rather than features — OVF import edge cases, template handling, NVRAM save/restore logic, CA generation as a non-root user, Keycloak group handling. One CVE, CVE-2024-0822, appears in 4.5.6 and its 4.5.3 backport.

◆ Where it's heading

This reads as a mature platform in maintenance rather than one being developed. The parallel 4.5.3.x stream exists purely to carry fixes back to deployments that cannot move, and the two-year gap between 4.5.6 and 4.5.7 says more about the project's momentum than any individual change does. Nothing in these entries points toward new capability.

◆ Prediction

The entries do not support a confident call on where this goes next; the only observable pattern is long gaps punctuated by accumulated fix rollups, so another such rollup is the most that can be inferred.
