What is Ably?
Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.
What is Helm?
Helm runs two trains while v3 walks toward end-of-life
Helm maintains parallel v3.21.x and v4.2.x lines, releasing patches on both within minutes of each other. The v3 releases now carry an explicit end-of-life warning directing users to v4. Release notes are mostly boilerplate community links, with a short Notable Changes list when anything is worth naming.

◆ Current state
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.
◆ Where it's heading
The pattern is a realtime messaging company treating agent runs as the thing its network transports. Each AI Transport release closes a gap that would otherwise force developers to build around the channel — history reconciliation, crash recovery, changing direction mid-response, and now speaking a specific model provider's wire format. The LiveObjects work runs on a slower track and points the same way: path-based subscriptions that survive structural change are aimed at the fast-mutating state agents and collaborative apps produce.
◆ Prediction
Expect the codec pattern to extend to other model provider APIs beyond OpenAI Responses, and the LiveObjects path-based API to keep propagating across the remaining SDK languages after Java.
Helm
5.0INFRA · APIS
Helm runs two trains while v3 walks toward end-of-life
◆ Current state
Helm maintains parallel v3.21.x and v4.2.x lines, releasing patches on both within minutes of each other. The v3 releases now carry an explicit end-of-life warning directing users to v4. Release notes are mostly boilerplate community links, with a short Notable Changes list when anything is worth naming.
◆ Where it's heading
Both trains are in maintenance rather than feature mode. The recurring work is keeping the Kubernetes client libraries current — v1.36 in this window — and fixing concurrency defects in the v4 waiter and kube-client code that surface when install, upgrade, rollback and uninstall run against the same client. Where v4 does add anything, it is small and toolchain-shaped: goreleaser builds, a mustToToml template function, flag deprecations.
◆ Prediction
The dual-patch pattern will continue in lockstep until v3 reaches its announced end-of-life, after which only the v4 line should keep receiving releases. Nothing in these entries indicates a date for that cutover.
