Features & Improvements

New Tools: Added enrichment functionality to expand the toolset available to agents and workflows.

Rate Limit Increases: Increased rate limits across all subscription plans alongside improved socket connections. Users will now receive reconnection notifications when socket connections are interrupted, improving visibility into connection state changes.

Bug Fixes & Optimizations

Workflow Optimization: Improved loop and parallel regeneration performance while preventing duplicate agent tools from being created during workflow execution.

MCP Tool Timeout Handling: Fixed an issue where the Model Context Protocol (MCP) SDK's callTool method now properly respects custom timeout configurations, overriding the previous 60-second default timeout.

What Developers Need to Know

If you're building agents or workflows with Sim Studio, upgrade to take advantage of the new enrichment tools. The rate limit increases mean you can make more API calls per minute depending on your plan tier. If you're using MCP integrations, you can now configure tool timeout durations without being constrained by the 60-second default.
