v0.4.2

Key Changes

New utility for multiple MCP server management

Starting with this version, there is a new, convenient way to manage multiple MCP server instances. See #901 and examples/mcp/mcp-servers-example.ts

New import path for aisdk() from @openai/agents-extensions

If you've been using the @openai/agents-extensions package for aisdk() helper, we now recommend importing it from @openai/agents-extensions/ai-sdk. Both import paths still work for now, but the top-level import is deprecated and will be removed in v0.5.0.

AI SDK's useChat compatibility utility under @openai/agents-extensions/ai-sdk-ui

createAiSdkUiMessageStreamResponse from @openai/agents-extensions/ai-sdk-ui enables server routes in React/Next.js apps to stream data that can be consumed by useChat on the frontend. See #899 and examples/ai-sdk-ui.
