What is KubeArmor?

Every release in the feed is a candidate — the stable line is decided elsewhere.

KubeArmor's tracked feed contains only release candidates: three for 1.7.4 and one for 1.7.5, with no stable tag among them. The work divides into eBPF-level observability (DNS visibility moved from udp_sendmsg to udp_send_skb, DNS support and a verifier for kernel 6.17), platform compatibility (Ubuntu 26.04, openEuler 24.03 LTS-SP3, RHEL kernel iov handling), and supply-chain scoring — Renovate integration, workflow token permissions and provenance generation explicitly aimed at OpenSSF Scorecard numbers. Contribution is broad, with a dozen or more named authors per candidate.

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.

Every release in the feed is a candidate — the stable line is decided elsewhere.

◆ Current state

KubeArmor's tracked feed contains only release candidates: three for 1.7.4 and one for 1.7.5, with no stable tag among them. The work divides into eBPF-level observability (DNS visibility moved from udp_sendmsg to udp_send_skb, DNS support and a verifier for kernel 6.17), platform compatibility (Ubuntu 26.04, openEuler 24.03 LTS-SP3, RHEL kernel iov handling), and supply-chain scoring — Renovate integration, workflow token permissions and provenance generation explicitly aimed at OpenSSF Scorecard numbers. Contribution is broad, with a dozen or more named authors per candidate.

◆ Where it's heading

Kernel-version chase is the dominant constraint. An eBPF enforcement agent has to track kernel internals release by release, and a meaningful share of each candidate goes to keeping probes attached across new kernels and distributions rather than adding policy capability. The one genuine capability attempt in this window — TLD and subdomain enforcement — was merged and then reverted within the same release candidate, which suggests network-identity policy is being worked on and is not yet stable.

◆ Prediction

Expect TLD and subdomain enforcement to return once the regression behind the revert is resolved, and continued kernel and distribution matrix expansion. Whether 1.7.4 ever reached a stable tag is not visible in this feed.

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.
