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.
Four maintenance branches move in lockstep, with the actual changes hidden behind a link.
ansible-core is in pure maintenance mode across four concurrent branches — 2.18, 2.19, 2.20 and 2.21 — each cut on the same day within minutes of the others. The published release notes carry no feature text at all: every entry is a stub pointing at an external changelog plus wheel and tarball checksums. From the feed alone, the only observable signal is cadence and branch topology, not capability.

The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
Ably is treating agent conversations as a transport problem — sessions, resumability, and multi-client reconciliation — rather than as a model-integration problem, and the primitives shipping in AI Transport keep pointing that way. The Pub/Sub line is being pulled along behind it: LiveObjects path APIs and React hooks are the state layer those agent sessions need. The pre-1.0 SDK will keep breaking as the shape settles, which is a reasonable trade while the category is unsettled.
Expect AI Transport to keep adding provider codecs beyond OpenAI Responses and to approach an API freeze as breaking changes get more expensive. LiveObjects support should continue spreading across the language SDKs, following the Java path-based API with other platforms.
ansible-core is in pure maintenance mode across four concurrent branches — 2.18, 2.19, 2.20 and 2.21 — each cut on the same day within minutes of the others. The published release notes carry no feature text at all: every entry is a stub pointing at an external changelog plus wheel and tarball checksums. From the feed alone, the only observable signal is cadence and branch topology, not capability.
The pattern is a stable, heavily backported LTS-style train: release candidates for all live branches go out together on one day, then the finals land as a batch a week later. Two of the four RCs cut on 3 August (2.18.19rc1, 2.19.12rc1) promoted to finals on 10 August, while 2.20.8 and 2.21.3 remain in candidate state. That rhythm suggests a release process driven by a shared backport queue rather than per-branch feature work.
Expect 2.20.8 and 2.21.3 to promote from rc1 to final on the next batch date, with a fresh round of rc1 tags across all four branches shortly after. What lands inside them isn't visible from these entries.
