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.
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.

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.
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.
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.

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.
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.

One commit per release, and most of them are closing security holes in the Cloud Code and query paths.
Three branches patched in lockstep for an unauthenticated takeover — then patched again for the fix's regression.
Two maintained branches, a paired-release rhythm, and a window with no new features in it.
Three branches tagged on one day, with the actual release notes published somewhere else
Two supported branches, every release a bot-driven cherry-pick — authentik is in pure maintenance here
