1.0.0b2 (2026-04-24)

Breaking Changes

• Re-platformed onto agentserver-core 2.0 + agentserver-responses 1.0.
  • CopilotAdapter no longer extends FoundryCBAgent (removed in core 2.0).
  • Uses AgentHost + ResponseHandler composition model instead.
  • Hypercorn replaces uvicorn as the ASGI server.
  • _copilot_response_converter.py and _copilot_request_converter.py removed — replaced by ResponseEventStream builders from the responses package.

Features Added

• SSE streaming now uses correct RAPI event ordering (text_done → content_part.done → output_item.done → completed). The workaround of emitting completed before text_done is no longer needed.
• Built-in SSE keep-alive via ResponsesServerOptions(sse_keep_alive_interval_seconds=...). Custom heartbeat logic removed.
• ResponseEventStream builders provide typed, state-machine-validated RAPI event construction.
• Usage tracking (input/output tokens) included in response.completed event.
• Foundry model discovery with 24-hour disk cache.
• MCP OAuth consent event handling.

Bugs Fixed

• SSE streaming truncation on ADC (Envoy proxy) — fixed by Hypercorn + correct event ordering.
• Duplicate text in streaming responses — only ASSISTANT_MESSAGE_DELTA events emit deltas, not the final ASSISTANT_MESSAGE.
