About 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.
