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.
SuperTokens tags 12.0.12 three weeks after its seven-advisory security release.
SuperTokens is a self-hostable auth backend. v12.0.12 on Nov 5 ships with only a compare link and no notes. The previous release, 12.0.11, fixed seven advisories, added SAML replay protection and made IdP-initiated SAML login require an ACS URL allow-list. The v12.3.0 canary in September added an activity log of user lifecycle events.

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.

The stable 12.0 line is in patch mode, mostly security, while lifecycle events mature in the canary line. The gap between canary features and stable releases is still open.
It is unclear from the feed when the activity log reaches stable; more 12.0.x patches are the likely near-term output.
