What is Microcks?

Microcks is quietly wiring LLM example generation into an API mocking tool built for Kubernetes.

Three release candidates are visible — 1.14.0-rc1 and rc2 in March 2026, then 1.15.0-rc1 in June. The 1.14 line added Sync-to-Async triggers with trigger info propagated to the async minion, pushed the Helm chart as an OCI artifact, fixed API health checks under bad connection configuration, and extended OpenAI-based example generation to the GPT-5 family. 1.15.0-rc1 is largely platform upkeep: Angular upgraded to v21, netty explicitly embedded in the native image, GraphQL extensions, paginated topic ARN lookup, and a corrected OpenAPI overlay export shape.

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.

Microcks is quietly wiring LLM example generation into an API mocking tool built for Kubernetes.

◆ Current state

Three release candidates are visible — 1.14.0-rc1 and rc2 in March 2026, then 1.15.0-rc1 in June. The 1.14 line added Sync-to-Async triggers with trigger info propagated to the async minion, pushed the Helm chart as an OCI artifact, fixed API health checks under bad connection configuration, and extended OpenAI-based example generation to the GPT-5 family. 1.15.0-rc1 is largely platform upkeep: Angular upgraded to v21, netty explicitly embedded in the native image, GraphQL extensions, paginated topic ARN lookup, and a corrected OpenAPI overlay export shape.

◆ Where it's heading

Two threads run in parallel. The deployment story keeps getting tightened for Kubernetes — OCI-packaged Helm charts, native-image reflection registration, an Uber distribution — which is where a mock server has to live to be useful in CI. The more interesting thread is example generation: authoring realistic mock data is the actual work of using a mocking tool, and Microcks is putting a model behind it rather than asking users to write it. That work is still surfacing as commit lines rather than headline features.

◆ Prediction

The 1.15 line should reach a final release given the pre-release pattern, and the LLM example generation is the thread most likely to move from plumbing to a named capability if it keeps expanding.

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.
