KubeArmor vs rgm: at a glance
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 rgm?
A microbiome network model that got itself un-archived by deleting the dependency that killed it.
rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

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.
rgm
0.0INFRA · APIS
A microbiome network model that got itself un-archived by deleting the dependency that killed it.
◆ Current state
rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.
◆ Where it's heading
Three tags shipped inside two hours on one day, and the notes are candid about why: 1.1.0 held the actual work but was never released, 1.2.0 restated it under a higher version to signal the size of the change, and 1.2.1 answered CRAN pre-test feedback. Beyond the archival recovery, the visible work is housekeeping that had accumulated — a shadowed rmvnorm() definition, roxygen import tags that were silently emitting nothing, leftover C++ template scaffolding, and build artifacts under version control. The diagnostics function is the only genuinely new user-facing capability in the window.
◆ Prediction
The immediate task was restoring availability, and that is done; the open question the entries raise is whether losing the graphical-lasso warm start affects convergence in practice, which the new diagnostic plots are positioned to answer.
