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 Nomad?

Nomad's July release closed two Docker CVEs that let tasks escape their own driver configuration.

HashiCorp is cutting 1.11.x and 1.10.x Enterprise releases in matched pairs, seconds apart, with identical content. July's pair carried two Docker CVEs — one where allowed_modes or allow_privileged was not enforced before setting host namespace modes, one where a symlink let a task bypass volumes.enabled=false — plus a dynamic host volume bug that let a namespace-scoped delete permission remove another namespace's claims.

Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.

◆ 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.

Nomad

5.0

Nomad's July release closed two Docker CVEs that let tasks escape their own driver configuration.

◆ Current state

HashiCorp is cutting 1.11.x and 1.10.x Enterprise releases in matched pairs, seconds apart, with identical content. July's pair carried two Docker CVEs — one where allowed_modes or allow_privileged was not enforced before setting host namespace modes, one where a symlink let a task bypass volumes.enabled=false — plus a dynamic host volume bug that let a namespace-scoped delete permission remove another namespace's claims.

◆ Where it's heading

All three July fixes are the same failure: a boundary that was declared in configuration but not enforced at the point of use. Alongside that, the improvements are about degraded-mode operation — falling back to the client agent's Consul token when workload identity is unavailable, Vault token renewal retries, an optional Init hook for task driver plugins. Nomad is hardening the seams between the scheduler and the systems it delegates to.

◆ Prediction

Expect the paired Enterprise releases to continue at monthly cadence, with further fixes concentrated in the Docker driver and dynamic host volumes, where the isolation boundaries are newest.
