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.
GoCD's changelog is one maintainer keeping a 2010s CI server running on current runtimes.
The visible work is almost entirely platform upkeep, and nearly all of it is authored by a single contributor. The baseline has been walked forward repeatedly — Java 17 minimum, then building and packaging on Java 21, then Java 21 as the hard minimum with macOS x64 support dropped — while container images moved from Alpine and CentOS Stream to Wolfi and Chainguard, Rails went from 6.1 through 7.1, and Hamcrest was replaced by AssertJ across the test suite. 26.1.0 is the exception in substance: it carries security fixes described as affecting all prior GoCD versions, with an explicit recommendation to upgrade as soon as possible.

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.
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.

This is a mature product in custodial maintenance rather than development. The pattern across releases is dependency deduplication, dead code removal, deprecation cleanup and base image swaps — the work that keeps a large Rails and Java codebase installable and patchable on current operating systems. Feature entries are rare enough that their absence, rather than any particular change, is the signal.
Given the security advisory in 26.1.0 covers all earlier versions and the release notes point offsite for detail, the practical next step for operators is that upgrade. The entries show no queued feature work to project from.
