Roo Code 3.15.2 Release Notes (2025-05-02)

This release updates the Boomerang Orchestrator mode, improves Mermaid diagram rendering and error handling, enhances terminal performance, adds provider configuration options, and includes various UI fixes.

Boomerang Orchestrator Mode​

  • Enhanced Orchestrator (Boomerang) mode strictly orchestrates tasks.
  • No longer reads, writes, executes commands, or utilizes MCP servers; offloads these tasks to other modes.
  • Provides more predictable and secure task automation.

Inline Mermaid Rendering​

  • Made troubleshooting easier with clearer, multi-language error messages instead of displaying the invalid Mermaid markdown inline.

  • Added a convenient button to copy the diagram code for fixing or sharing.

  • Added Custom OpenAI API Base URL Support

    • Enabled users in restricted regions or with custom infrastructure to connect to OpenAI services.
    • Added a new configuration option in settings (thanks gongzhongqiang!).

  • Added Custom Header Support for OpenAI-Compatible Providers

    • Increased flexibility by allowing custom headers to be added, edited, or removed directly in settings.

Misc UI Improvements​

    • Resolved an issue where the chat input box height could jump unexpectedly when resizing the Roo Code window.
    • Provides a more stable and less distracting chat experience (thanks zhangtony239!).
  • Corrected Chat Layout Padding Issues
