Kubeshark rebuilt its backend for V2 and is redrawing the free tier around it.
Kubeshark is mid-transition from V1 to V2, announced for January 2026. The v52.11.0 release rewrote the backend entirely — V2 runs on the new implementation while V1 stays on the legacy one — and added cluster-wide L4 PCAP export plus L7-to-L4 mapping that ties API calls back to the TCP and UDP connections carrying them. Since then the releases have been smaller: connectivity map performance, per-flow PCAP files in snapshot archives, and a migration of every service domain from kubehq.com to kubeshark.com.
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.

Since then the releases have been smaller: connectivity map performance, per-flow PCAP files in snapshot archives, and a migration of every service domain from kubehq.com to kubeshark.com.
The product is moving down the stack. It started as an API-level traffic viewer and the recent work is all about L4 — connectivity maps, raw PCAP export, mapping L7 calls onto the connections beneath them — which puts it closer to a cluster-wide packet capture tool than a service-mesh observability dashboard. The licensing is moving in the opposite direction of the feature set: an almost-unlimited complimentary licence through the end of 2025 was replaced by one capped at 100 nodes, so the free tier is being defined rather than left open. Two releases also mention agentic infrastructure being staged but not yet usable.
Expect V2 to consolidate onto the new backend and the legacy V1 path to be dropped once the transition completes, since the release notes already describe V1 as being sunset. The staged agentic infrastructure is the most likely candidate for the next substantive feature, given it has been shipped inert twice.

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.
