What is Ably?
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
What is Gitea?
Gitea has switched to version 28 numbering; its feed has caught only the dev tags.
Gitea's feed captures release candidates and development tags, not final releases. The newest entry is a v29.0.0-dev tag on September 29 that adds the changelog for 28.0.0, which means Gitea has switched from 1.x numbering to major versions. Before that the visible entries were 1.26.0-rc0 in April, with Actions concurrency and a Terraform state registry, and 1.27.0-rc0 in June, with owner-level and global workflows and access-control fixes.

Ably
7.5INFRA · APIS
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
◆ Current state
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
◆ Where it's heading
The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.
◆ Prediction
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
Gitea
0.0INFRA · APIS
Gitea has switched to version 28 numbering; its feed has caught only the dev tags.
◆ Current state
Gitea's feed captures release candidates and development tags, not final releases. The newest entry is a v29.0.0-dev tag on September 29 that adds the changelog for 28.0.0, which means Gitea has switched from 1.x numbering to major versions. Before that the visible entries were 1.26.0-rc0 in April, with Actions concurrency and a Terraform state registry, and 1.27.0-rc0 in June, with owner-level and global workflows and access-control fixes.
◆ Where it's heading
Actions has been the main area of change across the 1.26 and 1.27 candidates, with reusable and scoped workflows, alongside repeated access-control fixes. The move to 28.0.0 numbering marks a new release scheme, but the feed has not captured its releases.
◆ Prediction
The feed is likely to keep showing dev tags rather than finals; the next visible entry may be a v29 release candidate.
