Elastic moves to 9.5 and takes cross-project search GA on Serverless.
Elastic Stack is now maintained on the 9.5, 9.4 and 8.19 lines, with patch releases arriving together across branches. The one substantive move is cross-project search reaching GA on Serverless, which links projects and queries them from one Discover or ES|QL session.
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.

Serverless is where the feature work shows up: cross-project search and Azure Private Link both landed there in about a month. The self-managed lines are getting steady patch trains, which keeps 8.19 viable as a long-lived branch.
Expect further Serverless parity with self-managed cluster features, and continued patch trains across branches. The patch notes shown here do not support a more specific call.

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.
