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.
Routinator 0.16 now validates ASPA and BGPsec, and runs strict, by default
Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. 0.16.0 shipped on 6 November with the candidate's defaults: ASPA and BGPsec on, strict validation on, the old flags replaced by --disable-aspa, --disable-bgpsec and --relaxed, plus RSC (RFC 9323), SLURM v2 and a new repository logging scheme that changes the /status JSON. Three days later 0.16.1 fixed a crash on start when TLS is enabled for the HTTP or RTR servers.

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.

Three days later 0.16.1 fixed a crash on start when TLS is enabled for the HTTP or RTR servers.
After a year of security fixes, Routinator has moved route-origin hardening from opt-in to default, which shifts the work onto operators who must now opt out. The quick 0.16.1 suggests the new release is meeting more varied deployments than the candidate did.
Further 0.16.x fixes as operators upgrade into the new defaults are the likely next releases; nothing in the entries points to new features soon.
