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.

What is Nextflow?

Nextflow 26.10.6 fixes caching and Wave retries as the 26.10 line settles.

Nextflow ships dated edge builds plus 25.10, 26.04 and 26.10 stable lines for backports. October was dominated by the Bitbucket Cloud token leak, patched across all three lines. Since then 26.10 has returned to normal maintenance: 26.10.5 added Wave SOCI lazy loading, and 26.10.6 on 12 November fixes resume for enums in modules, includes typed-process stage directives in the task hash, and retries Wave connection failures longer.

7.5

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.

5.0

Nextflow 26.10.6 fixes caching and Wave retries as the 26.10 line settles.

◆ Current state

Nextflow ships dated edge builds plus 25.10, 26.04 and 26.10 stable lines for backports. October was dominated by the Bitbucket Cloud token leak, patched across all three lines. Since then 26.10 has returned to normal maintenance: 26.10.5 added Wave SOCI lazy loading, and 26.10.6 on 12 November fixes resume for enums in modules, includes typed-process stage directives in the task hash, and retries Wave connection failures longer.

◆ Where it's heading

The 26.10 line is in steady patching, with most fixes touching the new typed-process and type-system features and the Wave container service. Several fixes affect task hashing and resume, which suggests the typed syntax is still being hardened for real pipelines.

◆ Prediction

Expect further 26.10.x patches around typed processes and Wave, with new features arriving first in edge builds.
