What is RabbitMQ?

Two parallel trains, and the 'maintenance' label is now hiding real feature work

RabbitMQ is maintaining 4.2.x and 4.3.x side by side, cutting matching patches into both on the same day, and both trains raised their floor to Erlang/OTP 27. Most of the window is correctness work in the Raft-backed subsystems — quorum queues losing metrics after a restart, leaders committing log entries too optimistically, classic queue index paths accumulating slashes, topic bindings with empty routing keys matching everything. The newest 4.3.5, however, is labelled a maintenance release while carrying encrypted management-UI login tokens, a new authentication logging category, ETag support on the definitions endpoint, and a self-deleting Shovel TTL.

What is SigNoz?

SigNoz is rebuilding its surfaces so agents can drive them, not just humans.

SigNoz is in a broad platform-hardening phase: dashboards rebuilt on the CNCF Perses schema, PromQL brought into conformance with Prometheus, Infrastructure Monitoring rebuilt around Kubernetes investigation, and an integration catalog expanding almost weekly. GCP metrics now land next to the rest of a team's telemetry with pre-built dashboards rather than requiring a trip to Cloud Monitoring. The v1 alert history endpoints are being removed over a security issue, with a documented v2 migration path.

Two parallel trains, and the 'maintenance' label is now hiding real feature work

◆ Current state

RabbitMQ is maintaining 4.2.x and 4.3.x side by side, cutting matching patches into both on the same day, and both trains raised their floor to Erlang/OTP 27. Most of the window is correctness work in the Raft-backed subsystems — quorum queues losing metrics after a restart, leaders committing log entries too optimistically, classic queue index paths accumulating slashes, topic bindings with empty routing keys matching everything. The newest 4.3.5, however, is labelled a maintenance release while carrying encrypted management-UI login tokens, a new authentication logging category, ETag support on the definitions endpoint, and a self-deleting Shovel TTL.

◆ Where it's heading

The bug pattern remains the tell: nearly every fix is in quorum queues, Khepri or Raft, which is where RabbitMQ moved its metadata and durability story after 4.3.0 removed Mnesia and partition-handling strategies outright. Layered on top is a steady tightening of the operational perimeter — protocol parsers rejecting malformed input strictly across AMQP 1.0, MQTT 5.0 and STOMP, pre-authentication frame limits on stream connections, HTTP API endpoints validating node membership, and headers that stop disclosing supported methods. Feature work is arriving inside patch releases rather than waiting for a minor.

◆ Prediction

Expect the 4.2.x train to slow toward end-of-life while 4.3.x patches keep absorbing both Khepri edge cases and security-surface work. The encrypted login token, currently opt-in behind a shared cluster secret, is the kind of setting that gets promoted to a default once rolling-upgrade friction is behind it.

SigNoz is rebuilding its surfaces so agents can drive them, not just humans.

◆ Current state

SigNoz is in a broad platform-hardening phase: dashboards rebuilt on the CNCF Perses schema, PromQL brought into conformance with Prometheus, Infrastructure Monitoring rebuilt around Kubernetes investigation, and an integration catalog expanding almost weekly. GCP metrics now land next to the rest of a team's telemetry with pre-built dashboards rather than requiring a trip to Cloud Monitoring. The v1 alert history endpoints are being removed over a security issue, with a documented v2 migration path.

◆ Where it's heading

Two threads run through the quarter. The first is compatibility as a migration argument — matching Prometheus semantics exactly and adopting an open dashboard specification both lower the cost of moving to SigNoz from whatever is already installed. The second is agent-readiness: the dashboard rebuild explicitly targets structured, token-light agent edits, and Noz keeps picking up context handling, so the operator SigNoz designs for is increasingly not a person.

◆ Prediction

Expect the schema-first treatment to spread to the other configurable surfaces, with alerts and saved views the obvious candidates, and the onboarding catalog to keep growing at its weekly clip. The v1 alert history endpoints should disappear within a release or two.
