What is Ably?
Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
What is ZoneMinder?
1.38.4 is a security release in all but name, closing ACL gaps across the API.
The 1.38 line is in maintenance, and 1.38.4 is almost entirely authorization work: per-monitor access control enforced on event, frame, zone, tag and media endpoints, two auth bypasses fixed in token validation, and SQL injection and overflow hardening. The 1.36 branch still receives backports, with 1.36.38 carrying its own SQL injection fix. The last feature release was 1.38.0 in February, which brought role-based access control, WebRTC and Go2RTC streaming, and the split of monitor function into separate capturing, analysing, and recording settings.

Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
◆ Current state
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
◆ Where it's heading
Ably is treating agent conversations as a transport problem — sessions, resumability, and multi-client reconciliation — rather than as a model-integration problem, and the primitives shipping in AI Transport keep pointing that way. The Pub/Sub line is being pulled along behind it: LiveObjects path APIs and React hooks are the state layer those agent sessions need. The pre-1.0 SDK will keep breaking as the shape settles, which is a reasonable trade while the category is unsettled.
◆ Prediction
Expect AI Transport to keep adding provider codecs beyond OpenAI Responses and to approach an API freeze as breaking changes get more expensive. LiveObjects support should continue spreading across the language SDKs, following the Java path-based API with other platforms.

1.38.4 is a security release in all but name, closing ACL gaps across the API.
◆ Current state
The 1.38 line is in maintenance, and 1.38.4 is almost entirely authorization work: per-monitor access control enforced on event, frame, zone, tag and media endpoints, two auth bypasses fixed in token validation, and SQL injection and overflow hardening. The 1.36 branch still receives backports, with 1.36.38 carrying its own SQL injection fix. The last feature release was 1.38.0 in February, which brought role-based access control, WebRTC and Go2RTC streaming, and the split of monitor function into separate capturing, analysing, and recording settings.
◆ Where it's heading
Every release since 1.38.0 has been consolidation of what that release opened up. RBAC shipped as a headline feature in February, and the four maintenance drops since have been finding the endpoints it did not cover — the familiar pattern when a permission model is retrofitted onto an API that predates it. Cadence is slow and irregular, months apart, with a 1.39 spec bump already visible in the repo but nothing from that series shipped.
◆ Prediction
Expect more per-endpoint ACL fixes on the 1.38 line before anything from 1.39 reaches release.
