Audit Logging & Compliance

Sim v0.5.93 ships a persistent audit log system with comprehensive route instrumentation to track user actions across the platform. The audit log now captures events for templates, billing, credentials, environment variables, deployments, and password changes—essential for enterprises requiring compliance tracking and security visibility.

Enterprise Access Controls

The release adds several security-focused features for enterprise deployments:

• Usage limit visibility: Non-admin enterprise members can no longer see usage limits and seats information, restricting sensitive billing data to administrators
• Integration allowlisting: A new ALLOWED_INTEGRATIONS environment variable enables self-hosted operators to restrict which integration blocks are available
• MCP domain allowlisting: The ALLOWED_MCP_DOMAINS environment variable allows administrators to control which domains MCP can connect to

Canvas & Locking Improvements

Locked blocks in the canvas now support outbound connections, providing more flexibility for workflow design. A critical fix prevents socket crashes when locking agent blocks, improving stability during collaborative editing.

Additional Fixes

The patch also addresses a Copilot shortcut conflict, updates integration normalization checks to handle lowercase values, and fixes redirect handling for Beluga tracking in shortlinks.
