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 Retool?

Retool is retiring standalone Assist while folding the same capability into the app builder.

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

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.

5.0

Retool is retiring standalone Assist while folding the same capability into the app builder.

◆ Current state

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

◆ Where it's heading

The agent is being consolidated into the app builder rather than offered as a separate assistant, and Assist's removal is the clearest statement of that. Alongside it, the controls an administrator needs before letting an agent touch production data are arriving in the same cadence — resource-level policies, token management, permission migrations. Retool is treating agent capability and agent governance as one shipping problem.

◆ Prediction

Access policies should extend past PostgreSQL to other resource types as they exit beta, and the app-building agent will likely gain review or approval steps of its own.
