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 MISP?

MISP extends instance-to-instance sync to collections while a security-hardening program runs underneath

MISP is shipping on a roughly two-week cadence, and three tracks run through every release. The first is federation: 2.5.43 added collection synchronisation between instances in both pull and push directions, with per-server toggles and feature negotiation. The second is a sustained security program — 2.5.40, 2.5.41 and 2.5.42 are all substantially security releases, with 2.5.42 alone closing two RCE vectors and a mass-assignment sweep across a 74-controller review. The third is the Overmind UI migration to Bootstrap 5, which lands a batch of converted views in nearly every release.

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.

MISP extends instance-to-instance sync to collections while a security-hardening program runs underneath

◆ Current state

MISP is shipping on a roughly two-week cadence, and three tracks run through every release. The first is federation: 2.5.43 added collection synchronisation between instances in both pull and push directions, with per-server toggles and feature negotiation. The second is a sustained security program — 2.5.40, 2.5.41 and 2.5.42 are all substantially security releases, with 2.5.42 alone closing two RCE vectors and a mass-assignment sweep across a 74-controller review. The third is the Overmind UI migration to Bootstrap 5, which lands a batch of converted views in nearly every release.

◆ Where it's heading

The security work reads as a deliberate audit rather than incident response — the fixes are systematic (mass-assignment and broken-access-control across the controller layer, OIDC hardening, ACL enforcement on cluster search) and credited to named external researchers across four consecutive releases. Alongside it, the interop surface keeps widening: TAXII 2 conformance and scheduled push, STIX moved onto the upstream misp-stix library, and now collection sync. The Overmind migration is the slow constant, converting the UI tab by tab rather than in one cutover.

◆ Prediction

The Overmind migration and the Pivotick pivot explorer are both mid-rollout, so the next releases should continue converting views and fill out Pivotick rather than open a new track. Given the pattern of the last four releases, expect further externally-reported security fixes to ship alongside them.
