What is Logstash?

PQ compression and ES|QL preview land while weekly plugin churn drives the release cadence.

Logstash is in a steady maintenance phase across the 9.0–9.3 lines, with most weekly releases dominated by plugin dependency bumps (Netty, Avro, kotlin-stdlib) and small fixes. The substantive 9.x work — Persistent Queue compression via ZSTD, batch-size metrics, and ES|QL support in Technical Preview for the Elasticsearch input/filter — represents real capability gains for operators tuning throughput and storage. Security and credential-handling hygiene (sasl_jaas_config redaction, encoded API-key formats) shows up consistently across plugin updates.

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.

PQ compression and ES|QL preview land while weekly plugin churn drives the release cadence.

◆ Current state

Logstash is in a steady maintenance phase across the 9.0–9.3 lines, with most weekly releases dominated by plugin dependency bumps (Netty, Avro, kotlin-stdlib) and small fixes. The substantive 9.x work — Persistent Queue compression via ZSTD, batch-size metrics, and ES|QL support in Technical Preview for the Elasticsearch input/filter — represents real capability gains for operators tuning throughput and storage. Security and credential-handling hygiene (sasl_jaas_config redaction, encoded API-key formats) shows up consistently across plugin updates.

◆ Where it's heading

The product is consolidating its role as the configurable ingest tier of the Elastic stack rather than chasing new categories. Investment is concentrated on operational efficiency — PQ compression, average batch metrics, JDBC concurrency lifts — and on tightening integration with newer Elasticsearch capabilities like ES|QL. Plugin maintenance burden is high but treated as first-class, suggesting the team has accepted the long tail of integrations as the durable surface area.

◆ Prediction

Expect ES|QL support to graduate from Technical Preview to GA in the next minor, and PQ compression to become the default once the rollback-barrier risk has aged out. Watch for further telemetry surfaces aimed at sizing — the batch-metrics work points toward a guided-tuning story.

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.
