v0.6.9...02304da

Release call:

🟢 GREEN LIGHT TO SHIP Minor-version bump aligns with the user-facing behavior changes; risks are manageable.

Scope summary:

• 40 files changed (+3013/-391); key areas touched: src/agents/mcp/, src/agents/run.py, src/agents/realtime/, src/agents/models/, tests/, examples/, CI workflows, docs, version bump.

Risk assessment (ordered by impact):

1. Handoff/session behavior defaults changed
   • Risk: MODERATE. Default nest_handoff_history now disabled and list inputs auto-append to history, which can change downstream prompts and tool usage for existing apps.
   • Files: src/agents/run.py, tests/test_agent_runner.py, tests/test_run_step_processing.py, tests/test_session.py
2. Default model settings for gpt-5.1/5.2
   • Risk: MODERATE. Switching to reasoning effort none alters model behavior/quality/cost expectations for default settings.
   • Files: src/agents/models/default_models.py, tests/models/test_default_models.py
3. MCP lifecycle and cancellation semantics
   • Risk: LOW. New manager and explicit CancelledError handling could surface previously suppressed cancellation in edge cases.
   • Files: src/agents/mcp/manager.py, src/agents/mcp/server.py, tests/mcp/test_mcp_server_manager.py

Notes:

• Working tree clean; tags are local only per instructions (latest tag v0.6.9).
• TARGET is HEAD at 02304da9e74ed9b614441d49cb6c9ad6d3af7113.
• CI/test status not verified here; assume $code-change-verification handled in CI for this release candidate.
