v1.67.1

CopilotKit v1.67.1

A patch release on the 1.67 line. No source changes to the 16 monorepo packages — they are republished so the 1.67 line ships alongside Channels v0.8.1, which fixes managed Channels sessions getting stuck in reconnecting after an error-only websocket failure (#6443).

Install

npm install @copilotkit/react-core@1.67.1 @copilotkit/react-ui@1.67.1 @copilotkit/runtime@1.67.1

Channels fixes (shipped as Channels v0.8.1)

• Channels recover from error-only websocket failures (@copilotkit/channels-intelligence) — Node 22's built-in WebSocket can report a failed HTTP upgrade (including a transient 502) as an error event with no matching close. Phoenix schedules socket reconnects only from its close handler, so a managed Channels session could stay in reconnecting until the process restarted. An established transport that emits error without close now starts a 100 ms fallback that cycles the Phoenix socket; the fallback is cancelled on a normal close, a successful open, or an intentional disconnect, so an error followed by a close does not double-reconnect and Phoenix's own rejoin behavior is preserved. Hosts recover automatically — no new public options or host configuration. Initial-connect diagnosis, Phoenix backoff, connection states, and the reconnect give-up window are unchanged. (#6443)

Repository

• ~56 MB of unreferenced git-LFS assets removed — four files under assets/ that nothing in the tree referenced (demo.gif, animated-banner.gif, travel-planner-gif.gif, proejct-perplexity-clone.png) are gone, so a fresh clone no longer pays for them. assets/license-badge.svg — the only asset still referenced from the README — is untouched. Credit to @VZBYang, who identified assets/demo.gif in #4314. (#6448)

Dependencies

• Runtime's Channels dependencies resolve to 0.8.1 — the published @copilotkit/runtime picks up @copilotkit/channels-core@^0.8.1 / @copilotkit/channels-intelligence@0.8.1 from the concurrent Channels release.
• @ag-ui/* unchanged from 1.67.0 — @ag-ui/langgraph at 0.0.42, @ag-ui/a2ui-middleware at 0.0.10, @ag-ui/mcp-apps-middleware at 0.0.3, @ag-ui/mcp-middleware at 0.0.1, @ag-ui/core / @ag-ui/client / @ag-ui/encoder at 0.0.57.
• @copilotkit/license-verifier stays at ~0.5.0.
