Summary

This release introduces workflow validation for StopEvents, adds Measure Space tools, and provides several bug fixes for OpenAI, Anthropic, and Google GenAI integrations.

⚠️ Breaking Changes

  • The 'reasoning_effort' keyword argument in OpenAIResponses has been moved into the 'reasoning_options' dictionary. Update code passing 'reasoning_effort' directly to use the new dictionary structure.

Migration Steps

  1. Update OpenAI integration code to wrap 'reasoning_effort' inside a 'reasoning_options' dictionary.

✨ New Features

  • Added StopEvent step validation in workflows to ensure only one step handles the event.
  • Added support for passing static AWS credentials to Anthropic Bedrock.
  • Introduced new weather, climate, air quality, and geocoding tools from Measure Space.
  • Added headers handling to BasicMCPClient in MCP tools.

🐛 Bug Fixes

  • Added compatibility check for 'tool_required' LLM argument.
  • Implemented batch size validation (limit 96) for Cohere embeddings API.
  • Fixed tool configuration handling for Anthropic when no tools are provided.
  • Corrected function calling mode to use proper 'auto' mode for Google GenAI.
  • Resolved field typing issues in OpenAI LLM API.
  • Fixed broken 'reasoning_effort' parameter in OpenAIResponses.
