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.
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.

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.
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.
