What is kOps?

kOps is tightening cluster defaults and dropping the platforms it no longer wants to carry.

kOps publishes alpha and beta tags rather than finals to this feed, with long commit lists dominated by provider-specific work. The 1.36 cycle removed Amazon Linux 2 support outright and changed omitted authorization to default to RBAC instead of AlwaysAllow. The 1.37 alpha continues along provider lines: Azure node identity now uses the IMDS attested metadata document, AWS reconciles target group health check changes on existing groups, GCE does the same for HTTP health checks, and Linode gained SSH key management.

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.

kOps is tightening cluster defaults and dropping the platforms it no longer wants to carry.

◆ Current state

kOps publishes alpha and beta tags rather than finals to this feed, with long commit lists dominated by provider-specific work. The 1.36 cycle removed Amazon Linux 2 support outright and changed omitted authorization to default to RBAC instead of AlwaysAllow. The 1.37 alpha continues along provider lines: Azure node identity now uses the IMDS attested metadata document, AWS reconciles target group health check changes on existing groups, GCE does the same for HTTP health checks, and Linode gained SSH key management.

◆ Where it's heading

Two patterns run through these tags. The first is reconciliation — kOps is closing the gaps where it created a resource but never re-checked it, which is what turns a provisioning tool into something that can be run continuously. The second is deliberate narrowing: dropping Amazon Linux 2 and defaulting authorization to RBAC both trade compatibility for a safer, smaller supported matrix.

◆ Prediction

The health check reconciliation pattern has now landed for AWS and GCE in the same cycle, so Azure and the smaller providers are the likely next targets.

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.
