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 Parse Server?
Parse Server's alphas close an account-takeover bug and open 9.12 with Keycloak audience checks.
Parse Server spent November 4 to 10 on 9.11.1 security alphas. The latest close a bug where changing another user's password returned that user's session token, a Google Play Games adapter that accepted foreign player IDs, and a default upload filter that let RSS and Atom files through. 9.12.0 opened on November 10 with a Keycloak audience check, and alpha.2 fixes a LiveQuery event-loop block.

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.
Parse Server
5.0INFRA · APIS
Parse Server's alphas close an account-takeover bug and open 9.12 with Keycloak audience checks.
◆ Current state
Parse Server spent November 4 to 10 on 9.11.1 security alphas. The latest close a bug where changing another user's password returned that user's session token, a Google Play Games adapter that accepted foreign player IDs, and a default upload filter that let RSS and Atom files through. 9.12.0 opened on November 10 with a Keycloak audience check, and alpha.2 fixes a LiveQuery event-loop block.
◆ Where it's heading
Most releases are security fixes, many tied to published GHSA advisories, and they cluster around auth adapters, triggers and query limits. The new features also tighten auth, so the project is hardening its identity surface more than adding capability.
◆ Prediction
Expect more auth-adapter and LiveQuery advisories in the 9.12 alphas before a stable cut bundles them.
