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 HAProxy Kubernetes Ingress Controller?

HAProxy's ingress controller jumps to 3.4, drops Gateway API and config snippets.

After nineteen 3.2 patches, the controller released v3.4.0 on 12 November on top of HAProxy 3.4. It removes Gateway API support and config snippet annotations, announces further annotation deprecations, and retires the server-slot annotations by creating and deleting backend servers through HAProxy's runtime API. Custom resources that HAProxy rejects are now set aside and counted in a metric instead of breaking the config.

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.

H6.3

HAProxy's ingress controller jumps to 3.4, drops Gateway API and config snippets.

◆ Current state

After nineteen 3.2 patches, the controller released v3.4.0 on 12 November on top of HAProxy 3.4. It removes Gateway API support and config snippet annotations, announces further annotation deprecations, and retires the server-slot annotations by creating and deleting backend servers through HAProxy's runtime API. Custom resources that HAProxy rejects are now set aside and counted in a metric instead of breaking the config.

◆ Where it's heading

The project is narrowing its configuration surface to its own custom resources: snippets and Gateway API are gone, annotations are being deprecated, and the 3.2 line had already added Frontend amendments through a custom resource. Runtime API server changes and the rejected-resource handling point to fewer reloads and fewer config-wide failures.

◆ Prediction

Expect 3.4 patch releases fixing migration problems for users who relied on snippets or deprecated annotations, and a published removal schedule for the annotations announced as deprecated.
