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.
Helm 4.3.2 is a small patch; 4.4 is set for January 13.
Helm runs two trains: 3.22 was the last Helm 3 minor, and Helm 4 carries development. 4.3.0 in September brought concurrent status computation, ownership checks before uninstall and reproducible archives. 4.3.2 on November 13 fixes registry clients so Helm can always configure the transport, corrects help text and bumps golang.org/x/net. The notes put 4.4.0 on January 13, 2027 and repeat that no Helm 3 minor releases will follow.

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.
Helm runs two trains: 3.22 was the last Helm 3 minor, and Helm 4 carries development. 4.3.0 in September brought concurrent status computation, ownership checks before uninstall and reproducible archives. 4.3.2 on November 13 fixes registry clients so Helm can always configure the transport, corrects help text and bumps golang.org/x/net. The notes put 4.4.0 on January 13, 2027 and repeat that no Helm 3 minor releases will follow.
Helm 4 is in a quiet patch phase between minors, and Helm 3 only gets dependency and security updates as it winds down. Users are being steered to Helm 4.
Expect a Helm 3 patch for dependency CVEs and a 4.4.0 release candidate in late December ahead of the January 13 date.
