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 k0s?
k0s ships another four-branch patch round, with an IPv6 service CIDR fix on 1.37 and 1.36.
On November 3 k0s released v1.37.2, 1.36.6, 1.35.10 and 1.34.13 within minutes of each other. The 1.37 and 1.36 releases remove a size limit on IPv6 service CIDRs and update containerd to 2.3.6; 1.37.2 also bumps kine, ORAS and troubleshoot. The 1.35 and 1.34 branches take only Kubernetes patch updates.

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.

5.0INFRA · APIS
k0s ships another four-branch patch round, with an IPv6 service CIDR fix on 1.37 and 1.36.
◆ Current state
On November 3 k0s released v1.37.2, 1.36.6, 1.35.10 and 1.34.13 within minutes of each other. The 1.37 and 1.36 releases remove a size limit on IPv6 service CIDRs and update containerd to 2.3.6; 1.37.2 also bumps kine, ORAS and troubleshoot. The 1.35 and 1.34 branches take only Kubernetes patch updates.
◆ Where it's heading
k0s now maintains four branches on a shared patch cadence, roughly one coordinated round a week after the 1.37 line opened on October 27. Fixes and dependency updates land on the newest two branches, while older ones receive only Kubernetes patches, which indicates where active support is concentrated.
◆ Prediction
Expect the next coordinated round to follow upstream Kubernetes patch releases, with 1.34 likely to stop receiving updates as 1.37 matures.
