What is Ably?
Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.
Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.
What is Nautobot?
Nautobot ships SSO group control and a Saved View permissions rework to both branches at once.
Nautobot maintains two branches in parallel and cuts them minutes apart. The 08-31 pair carries the same core work to both: an SSO_SYNC_GROUPS setting that restricts which claimed groups are synced, group sync that now properly revokes memberships and staff status when the claim empties, a Saved View set-default endpoint that needs no Saved View permissions, and two GitPython security bumps. The 3.2 branch alone takes a filterset overhaul that stops many filters returning duplicate rows.

Ably
7.5INFRA · APIS
Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.
◆ Current state
Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.
◆ Where it's heading
The direction is Ably as AI agent infrastructure. LiveObjects' own documentation positions it explicitly for 'AI agents, live configurations, and collaborative experiences.' The AI Transport SDK is a purpose-built layer for agentic workflows — durable sessions, multi-turn conversations, tool execution — layered on Ably's realtime primitives. This is a deliberate expansion from realtime messaging platform into the transport layer that agents run on.
◆ Prediction
The AI Transport SDK will add more model provider codecs — the OpenAI Responses integration suggests Anthropic or Gemini support is next. LiveObjects needs to reach stable across remaining SDKs (Python, .NET) before the feature can be adopted uniformly.
Nautobot
5.0INFRA · APIS
Nautobot ships SSO group control and a Saved View permissions rework to both branches at once.
◆ Current state
Nautobot maintains two branches in parallel and cuts them minutes apart. The 08-31 pair carries the same core work to both: an SSO_SYNC_GROUPS setting that restricts which claimed groups are synced, group sync that now properly revokes memberships and staff status when the claim empties, a Saved View set-default endpoint that needs no Saved View permissions, and two GitPython security bumps. The 3.2 branch alone takes a filterset overhaul that stops many filters returning duplicate rows.
◆ Where it's heading
The permissions surface is where the sustained attention is. Saved Views get ownership and permission checks applied consistently across form, API and default-setting paths, an old association endpoint is deprecated in favour of a scoped one, and the documentation is filled in around who actually needs which grant. Alongside it, SSO group handling is being tightened from both ends — restricting what syncs in, and correctly revoking what should no longer apply.
◆ Prediction
With the user-saved-view-associations endpoints now deprecated and the filter distinct flag derived rather than defaulted, expect the next releases to remove those endpoints on the 3.x line and continue the app-facing filterset test rollout.
