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.
WireMock 4.0 beta.42 can record every request header, still in beta.
WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. After a quiet month, beta.42 and beta.43 arrived on November 12 and 13: recording can now capture all request headers with exclusions, a new extension point lets code react to served messages, and the rest is Dependabot bumps.

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.
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.
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.

The 4.0 betas are still mostly fixes and dependency updates, with small additions to recording and message channels. Nothing signals a final release yet.
Expect more numbered betas with recording and message-channel fixes; when 4.0 goes final is not visible from these entries.
