What is CRI-O?

CRI-O ships patch releases across three branches with empty change notes

CRI-O's changelog is patch releases across supported branches, now including v1.35.x alongside v1.34.x. The three newest notes, v1.35.10, v1.34.15 and v1.34.14, list empty Dependencies and Feature sections with no items. Earlier 1.34 patches carried dependency updates and regression fixes.

What is Microcks?

Microcks 1.16 candidate adds IBM MQ mocking and moves to hardened images with faster startup

Microcks 1.16.0-rc1 is the first release candidate since June's 1.15.0-rc1. It adds AsyncAPI mocking and testing for IBM MQ, request/reply handling for Google Pub/Sub with Workload Identity auth, TLS on the HTTP endpoint and external references in the OpenAPI-to-MCP tool converter. The container images switch to Docker Hardened Images by default and replace Spring AOT with a Leyden AOT cache to cut startup time.

CRI-O ships patch releases across three branches with empty change notes

◆ Current state

CRI-O's changelog is patch releases across supported branches, now including v1.35.x alongside v1.34.x. The three newest notes, v1.35.10, v1.34.15 and v1.34.14, list empty Dependencies and Feature sections with no items. Earlier 1.34 patches carried dependency updates and regression fixes.

◆ Where it's heading

The project is in steady maintenance on several Kubernetes-aligned branches. The published notes have stopped describing changes, so users cannot see what a patch contains from the feed.

◆ Prediction

More patch releases on 1.34 and 1.35 are likely at the same cadence; whether notes will return is unclear.

Microcks 1.16 candidate adds IBM MQ mocking and moves to hardened images with faster startup

◆ Current state

Microcks 1.16.0-rc1 is the first release candidate since June's 1.15.0-rc1. It adds AsyncAPI mocking and testing for IBM MQ, request/reply handling for Google Pub/Sub with Workload Identity auth, TLS on the HTTP endpoint and external references in the OpenAPI-to-MCP tool converter. The container images switch to Docker Hardened Images by default and replace Spring AOT with a Leyden AOT cache to cut startup time.

◆ Where it's heading

The project keeps broadening the messaging systems it can mock, now reaching enterprise brokers like IBM MQ and Amazon MQ over TLS. In parallel it is reworking its runtime for faster cold starts and smaller attack surface, and the MCP tool converter shows it treating API specs as inputs for AI agents as well as tests.

◆ Prediction

Further 1.16 candidates are likely to fix AOT and hardened-image edge cases, since this candidate already carries several JVM crash and probe fixes tied to that switch.
