Key Features

Sim Studio v0.6.2 introduces several developer-facing improvements:

• Iframe Embedding: The chat UI can now be embedded in iframes through updated Content Security Policy (CSP) headers, enabling integration with external applications and dashboards.
• Knowledge API Enhancement: New upsert document operation allows atomic document updates without managing separate create/delete operations.
• UI Improvements: Resizable divider between the chat and resource panels provides better layout control for users with varying workflow needs.
• Request ID Tracking: Enhanced mothership API now includes request IDs for better logging and debugging support.

Fixes & Infrastructure

This release addresses production stability issues:

• Database Connection Pool: Reduced connection pool sizes to prevent exhaustion under load
• File Uploads: Fixed mothership file upload functionality that was failing in the previous release
• Workspace Switching: Corrected an issue where stale placeholder data could corrupt the workflow registry when switching workspaces
• Durable Execution Diagnostics: Foundation work added for improved execution logging and troubleshooting

Developer Guidance

If you're embedding Sim Studio's chat UI in external applications, update your iframe integration to take advantage of the new CSP compatibility. For knowledge base operations, consider migrating to the new upsert operation to simplify your document management logic.
