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 Payload CMS?
Payload 4.0 beta 9 keeps old image versions and labels each login session.
Payload 4.0 is in public beta. Beta 8 added an OAuth server to the MCP plugin and moved image crops to request-time edits on the original file. Beta 9 builds on both: restoring a version brings back its upload variants and replays its crops, sessions carry labels and device details, and Node 24.22.3 becomes the minimum.

Ably
7.5INFRA · APIS
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.
Payload CMS
5.0INFRA · APIS
Payload 4.0 beta 9 keeps old image versions and labels each login session.
◆ Current state
Payload 4.0 is in public beta. Beta 8 added an OAuth server to the MCP plugin and moved image crops to request-time edits on the original file. Beta 9 builds on both: restoring a version brings back its upload variants and replays its crops, sessions carry labels and device details, and Node 24.22.3 becomes the minimum.
◆ Where it's heading
The 4.0 betas are finishing two systems: an auth model with refresh tokens and visible sessions, and an upload model that stores the original and replays edits. Each beta also nudges the minimum Node and framework versions up.
◆ Prediction
Expect a sessions management screen in the admin and more upload-transform fixes before a release candidate.
