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.
PocketBase v0.40.6 caps thumbnail memory and says releases will leave GitHub.
PocketBase v0.40.6 limits the source image size for thumbnail generation (about 262 megapixels by default, set via PB_THUMBS_MAX_SOURCE_PIXELS) to cut out-of-memory risk, adds extra file-bucket escape checks, and bumps Go for the eMudhra CA fix. It also switches the update command to a new host, and the maintainer says this is probably the last release published on GitHub. v0.22.57 backports the thumbnail cap and Go bump to the older line.

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.
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.
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.

It also switches the update command to a new host, and the maintainer says this is probably the last release published on GitHub. v0.22.57 backports the thumbnail cap and Go bump to the older line.
PocketBase continues to ship paired releases on v0.40 and the v0.22 LTS line, mostly security and stability fixes. Moving releases off GitHub to the maintainer's own host is the larger change, and it affects how every self-hoster updates.
The next release should arrive through the new host rather than GitHub; expect continued backports to v0.22 and further work on thumbnail memory use.
