Resend
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
A side-by-side editorial comparison of Prowler and Thanos — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.
Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.

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.
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.

The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.
The centre of gravity is multi-tenant operation. Per-endpoint configuration and tenant lifecycle handling are what an operator needs to run one Thanos install for many teams rather than one per team, and the Query fanout view is the observability that makes such a topology debuggable. The parallel fixes to multi-tier query setups — preserving external label matchers across Query A → Query B → Sidecar chains — point at the same reality: deployments are getting deeper, not just wider.
A 0.42.0 stable should follow once the *os.Root regressions settle. The RC notes are cumulative and the feed is quiet since June, so treat cadence here as release-train artefact rather than a slowdown in the project.
