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 Gloo Gateway?
Gloo Gateway is running four branches in parallel and shipping nothing but upkeep to all of them.
Gloo Gateway is in pure maintenance across four supported lines — 1.18, 1.19, 1.20 and 1.21 — with releases landing in same-day batches that carry identical payloads. The last month produced Go and oras-go bumps, a Helm readiness-probe fix, and a revert of an admission-time upstream validation change that turned out to be breaking. The only additive change in the window was hostRewriteLiteral support in the shadowing plugin, and it landed on 1.21 alone.

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.
Gloo Gateway
5.0INFRA · APIS
Gloo Gateway is running four branches in parallel and shipping nothing but upkeep to all of them.
◆ Current state
Gloo Gateway is in pure maintenance across four supported lines — 1.18, 1.19, 1.20 and 1.21 — with releases landing in same-day batches that carry identical payloads. The last month produced Go and oras-go bumps, a Helm readiness-probe fix, and a revert of an admission-time upstream validation change that turned out to be breaking. The only additive change in the window was hostRewriteLiteral support in the shadowing plugin, and it landed on 1.21 alone.
◆ Where it's heading
The release stream reads as a supported-branch treadmill rather than a development line: each fix is authored once and fanned out to every branch within twenty minutes. That the team reverted its own admission-validation change rather than gate it suggests a low tolerance for behavioral risk on these branches. New capability is being held back from the maintenance stream, so whatever is being built is not visible in this feed.
◆ Prediction
Expect the same pattern to continue — paired dependency bumps and single-PR fixes replicated across 1.19 through 1.21, with any reworked upstream-validation behavior reappearing behind an opt-in rather than as a default.
