When the backend emits RunErrorEvent via the AG-UI protocol, several
components did not handle it:
- ProxiedCopilotRuntimeAgent: isRunning stayed true, causing
data-copilot-running to never transition to false (infinite spinner)
- StateManager: activeRun entries were never cleaned up, runFinished
flag never set (stale state on subsequent runs)
- Angular CopilotKitAgent: same isRunning bug as the proxy agent
- useAgentNodeName: node name stuck at last step instead of "end"
onRunErrorEvent is distinct from onRunFailed — the former handles
protocol-level RUN_ERROR events from the backend, the latter handles
local exceptions (network errors, deserialization failures).
Incorporates the V1/V2 flat package consolidation (96885b595). All our
thread-isolation changes auto-merged to the new package paths. Three
content conflicts resolved (import paths updated from @/ aliases to
relative paths and @copilotkitnext/* to @copilotkit/*):
- packages/react-core/src/v2/hooks/use-agent.tsx
- packages/react-core/src/v2/hooks/use-render-custom-messages.tsx
- packages/react-core/src/v2/components/chat/CopilotChatMessageView.tsx
File location conflict resolved: use-agent-thread-isolation.test.tsx
moved from packages/v2/react/... to packages/react-core/src/v2/...
Flatten all packages from packages/v1/* and packages/v2/* into packages/* —
every package now lives directly under the @copilotkit/ scope with no v1/v2
subdirectories.
- Move all v1 packages (react-core, react-ui, runtime, shared, etc.) from
packages/v1/* to packages/*
- Absorb v2 react code into packages/react-core/src/v2/ (exported via /v2 subpath)
- Absorb v2 agent code into packages/runtime/src/agent/ (exported via /v2 subpath)
- Move v2 packages (core, angular, demo-agents, etc.) to packages/*
- Replace all @copilotkitnext/* imports with @copilotkit/* equivalents
- Keep @copilotkitnext/angular as the sole exception (angular remains on next)
- Update CI workflows, renovate config, release scripts for flat structure
- No public API surface changes — all exports fields are preserved
