Key Changes

This minor release does not introduce a breaking change, but it includes a notable Realtime default update plus new MCP capabilities and runtime stability fixes. Highlights are:

  • The default websocket Realtime model is now gpt-realtime-1.5, so new Realtime agent setups use the newer model without extra configuration.
  • MCPServer now exposes list_resources(), list_resource_templates(), and read_resource(), and MCPServerStreamableHttp now exposes session_id so streamable HTTP sessions can be resumed across reconnects or stateless workers.
  • Chat Completions integrations can now opt into reasoning-content replay via should_replay_reasoning_content, improving provider-specific reasoning/tool-call continuity for adapters such as LiteLLM/DeepSeek.
  • Fixed several runtime and session edge cases, including concurrent first writes in SQLAlchemySession, compaction requests with orphaned assistant message IDs after reasoning stripping, remove_all_tools() leaving MCP/reasoning items behind, and a race in the function-tool batch executor.
