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 Argo Rollouts?
An RC-only feed where 1.9's headline change was reverted before it shipped.
Every entry in this window is a release candidate; no GA tag appears at all. The 1.9 line spent three RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn. That change would have narrowed .status.selector to report only the stable ReplicaSet for traffic-routed canaries so HPA stopped counting canary pods in its desired-replica math. The 1.10.0-rc1 notes are dominated by build and dependency work.

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.
Argo Rollouts
0.0INFRA · APIS
An RC-only feed where 1.9's headline change was reverted before it shipped.
◆ Current state
Every entry in this window is a release candidate; no GA tag appears at all. The 1.9 line spent three RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn. That change would have narrowed .status.selector to report only the stable ReplicaSet for traffic-routed canaries so HPA stopped counting canary pods in its desired-replica math. The 1.10.0-rc1 notes are dominated by build and dependency work.
◆ Where it's heading
The visible direction is operational rather than behavioural: notifications broadened to Teams workflows and NATS.io, a build system parameterized for company forks, CI skipped for docs-only changes, a move to pnpm. The selector revert says the project would rather live with awkward HPA math than break autoscaling for existing users, so progressive-delivery mechanics stay where they are.
◆ Prediction
1.10.0 looks likely to land close to rc1 — dependency, CVE and notification work with no controller-semantics change — and the HPA selector question stays open unless it returns behind an opt-in flag.
