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 Jackett?
Jackett keeps up its daily indexer fixes, adding trackers and chasing domain moves.
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release about every day. The November 11 and 12 builds added the private sites bytepeer and an API-based cyanbug and worked around snowpt's removed download links; the November 13 build moves dontorrent to a new domain.

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.
Jackett
5.0INFRA · APIS
Jackett keeps up its daily indexer fixes, adding trackers and chasing domain moves.
◆ Current state
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release about every day. The November 11 and 12 builds added the private sites bytepeer and an API-based cyanbug and worked around snowpt's removed download links; the November 13 build moves dontorrent to a new domain.
◆ Where it's heading
The work stays reactive: trackers change domains, logins and page layouts, and Jackett adjusts definitions within a day. A recurring sub-pattern is moving sites to API-based connections, as with magnetz last week and cyanbug now.
◆ Prediction
More trackers moving from page scraping to API or API-key connections is the most visible pattern to continue, alongside the usual daily domain fixes.
