kOps deletes gossip DNS and the protokube binary, and spends the room on Akamai.
kOps publishes alpha and beta tags to this feed rather than finals, and 1.37.0-beta.1 is the largest cut in its visible history. Gossip DNS is gone, along with the protokube binary that served it, Classic Load Balancer support for the API, and Kubernetes 1.31. In the same tag Akamai — renamed from Linode across the codebase — grows from SSH-key handling into a provider with its own network model, subnets, instance management and etcd block storage volumes.
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.

In the same tag Akamai — renamed from Linode across the codebase — grows from SSH-key handling into a provider with its own network model, subnets, instance management and etcd block storage volumes.
The deliberate narrowing this feed has shown since 1.36 has stopped being incremental. Removing gossip means every cluster now needs real DNS, which ends the configuration that let kOps stand up clusters without a hosted zone. The room that deletion frees is going two visible places: a genuinely new cloud provider in Akamai, and a smaller binary, via grpcnotrace, a forked text/template that lets the linker prune, and a minimal TOML writer replacing go-toml.
Akamai moved from SSH keys to subnets, instances and etcd volumes inside a single tag, so it is the provider most likely to keep gaining tasks next. With a gossip migration guide already written, the remaining 1.37 work is the removal reaching users rather than more subtraction.

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.
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
