The 2.11 branch is pure upkeep — two CVEs and a CONNECT rework in three weeks.
Traefik's 2.11 line is on maintenance duty and every release in the window is either an advisory or a dependency bump. Two GHSA-tracked CVEs landed three weeks apart, and 2.11.53 reworked CONNECT handling — deferring the payload until the backend accepts the tunnel, and keeping CONNECT requests out of the connection pool — with a migration note attached because the behaviour change is visible to users.
Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.
Traefik's 2.11 line is on maintenance duty and every release in the window is either an advisory or a dependency bump.

This is a long-term support branch behaving like one: security response, Kubernetes CRD correctness, and library currency across tracing, gRPC, compression and TLS dependencies. The one substantive change, the CONNECT rework, is a proxying-correctness fix rather than a feature, and the fact it needed a migration guide entry says the old behaviour was being relied on.
Expect 2.11.x to keep producing small advisory-and-dependency releases at a two-to-three week cadence, with anything new landing on the newer major instead.
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.
The pattern is a realtime messaging company treating agent runs as the thing its network transports. Each AI Transport release closes a gap that would otherwise force developers to build around the channel — history reconciliation, crash recovery, changing direction mid-response, and now speaking a specific model provider's wire format. The LiveObjects work runs on a slower track and points the same way: path-based subscriptions that survive structural change are aimed at the fast-mutating state agents and collaborative apps produce.
Expect the codec pattern to extend to other model provider APIs beyond OpenAI Responses, and the LiveObjects path-based API to keep propagating across the remaining SDK languages after Java.
