What is Argo Rollouts?

An RC-only feed where 1.9's headline change was reverted before it shipped.

Every entry in this window is a release candidate; no GA tag appears at all. The 1.9 line spent three RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn. That change would have narrowed .status.selector to report only the stable ReplicaSet for traffic-routed canaries so HPA stopped counting canary pods in its desired-replica math. The 1.10.0-rc1 notes are dominated by build and dependency work.

What is Prowler?

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

Argo Rollouts
INFRA · APIS
0.0

An RC-only feed where 1.9's headline change was reverted before it shipped.

◆ Current state

Every entry in this window is a release candidate; no GA tag appears at all. The 1.9 line spent three RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn. That change would have narrowed .status.selector to report only the stable ReplicaSet for traffic-routed canaries so HPA stopped counting canary pods in its desired-replica math. The 1.10.0-rc1 notes are dominated by build and dependency work.

◆ Where it's heading

The visible direction is operational rather than behavioural: notifications broadened to Teams workflows and NATS.io, a build system parameterized for company forks, CI skipped for docs-only changes, a move to pnpm. The selector revert says the project would rather live with awkward HPA math than break autoscaling for existing users, so progressive-delivery mechanics stay where they are.

◆ Prediction

1.10.0 looks likely to land close to rc1 — dependency, CVE and notification work with no controller-semantics change — and the HPA selector question stays open unless it returns behind an opt-in flag.

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

◆ Current state

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

◆ Where it's heading

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.

◆ Prediction

Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.
