@ag-ui/claude-agent-sdk@0.0.9

• Fixed clone() of ClaudeAgentAdapter, which previously lacked state maps and threw "Cannot read properties of undefined (reading 'has')" in hosts that clone agents per request, such as CopilotKit runtime.
• Clones now share per-thread state (bindings, admitted, activeQueries, sessions) with the original.
• Frontend tool parameter schemas are now converted from JSON Schema recursively, preserving nested object properties, array item schemas, required fields, enums, const, nullable/union types and descriptions.
• Nested objects no longer strip undeclared keys during parsing.
• Preserved raw frontend outcomes during native recovery and replay saved tool results after executor failure.
• Preserved final assistant identity without streaming and reconciled superseded recovery deliveries.
• Accept public interrupt answers and saved-result retries.
• Recover child dependency graphs, internal state, parallel root and frontend results across restarts from canonical history.
• Clear completed diagnostics after child results and keep recovery guards across interrupted bridges.
• Recover native child approvals without event storage.

Breaking changes

• Frontend tool parameter schemas now carry nested structure instead of collapsing to any[] or open records; verify agents relying on the previous loose shapes.

@ag-ui/a2ui-middleware@0.0.16

• Maintenance release; no consumer-facing changes identified.

Breaking changes

None.

Python (PyPI) - published at 01:54:55 UTC

ag_ui_strands@1.0.4

• Fixed run handling so each run is driven from a single task, allowing OpenTelemetry spans to detach correctly.
• Prevents OTel context token reset errors caused by spanning multiple contextvars Contexts.

Breaking changes

None.

ag-ui-claude-sdk@0.2.4

• Stopped sending threadId/runId on TEXT_MESSAGE_* and TOOL_CALL_* events, which the AG-UI 1.0 schema rejects; avoids [ag-ui][enforce] strip warnings.
• Task tool calls now open an ActivitySnapshotEvent/ActivityDeltaEvent activity so frontends can render dispatched subagents distinctly; activities close on teardown and matching tool results.
• Preserve raw frontend outcomes and replay saved tool results during native recovery after executor failure.
• Preserve final assistant identity when not streaming.
• Reconcile superseded recovery deliveries and accept public interrupt answers and saved-result retries.
• Recover child dependency graphs, internal state, parallel root results, and native child approvals across restarts.
• Clear completed diagnostics after child results; keep recovery guards across interrupted bridges.

Breaking changes

• TEXT_MESSAGE_* and TOOL_CALL_* events no longer include threadId/runId; consumers relying on those fields must read them from RUN_STARTED or other run-level events.
