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.
What is Ably?
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.

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.

Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
◆ Current state
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
◆ Where it's heading
The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.
◆ Prediction
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
