GravityKit folds every GravityView extension into one Pro plugin.
A side-by-side editorial comparison of Microcks and Shuffle — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Shuffle tags builds almost daily, but the notes are empty.
Shuffle has tagged six 2.3.1 builds since November 3: release candidates 4 to 6 and three nightly builds. Only rc4 lists a change, a fix for a frontend crash; the rest link to commit comparisons. The more substantive rc1 in October handled AI agent actions in hybrid worker setups.

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.
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.

The project is iterating toward 2.3.1 with frequent builds, and the October notes show the work is about making AI agent steps run reliably in workflows. The empty release notes make it hard to see what each build changes.
A 2.3.1 final release looks close given the run of release candidates and nightlies, though the entries do not say what it will contain beyond fixes.
