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 DatoCMS?
DatoCMS is trading admin theming freedom for a guaranteed readability floor.
The dated feed has been quiet since late April, when the CLI work landed — npx datocms running without setup, and OAuth-based project linking. The live change is undated in this feed: from 25 August, new projects lose the custom admin palette and get only the monochromatic system, which derives every colour from one hue at WCAG AA contrast. Existing projects keep what they have. April also raised the Developer Plan CMA limit, added a plugin scaffold to the starter kits, and turned on antivirus scanning for every Media Area upload.

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.
DatoCMS
0.0INFRA · APIS
DatoCMS is trading admin theming freedom for a guaranteed readability floor.
◆ Current state
The dated feed has been quiet since late April, when the CLI work landed — npx datocms running without setup, and OAuth-based project linking. The live change is undated in this feed: from 25 August, new projects lose the custom admin palette and get only the monochromatic system, which derives every colour from one hue at WCAG AA contrast. Existing projects keep what they have. April also raised the Developer Plan CMA limit, added a plugin scaffold to the starter kits, and turned on antivirus scanning for every Media Area upload.
◆ Where it's heading
The pattern across this window is DatoCMS narrowing the decisions it hands users, and doing it deliberately. Antivirus scanning became automatic rather than optional; the CLI stopped requiring setup; and now admin theming stops being freeform for new projects because editors reported that freeform produced unreadable interfaces. Each of those removes a configuration surface and replaces it with a guaranteed outcome, which is a defensible direction for a CMS whose users are editors rather than the developers who set the project up. The agent-facing work — the Remote MCP Server and Agent Skills — sits on the same axis, giving models a fixed interface rather than a configurable one.
◆ Prediction
Expect the monochromatic system to eventually reach existing projects too, since a quality bar that applies only to new ones leaves the reported problem in place wherever it already exists. When that happens, or whether it will, is not stated here.
