Roo Code 3.39 Release Notes (Combined)

Roo Code 3.39 includes task-level provider profile persistence, improved multimodal workflows, new provider/model options, and reliability fixes across tool calling.

Features​

  • Task-level API configuration profiles: Roo can persist the selected provider profile per task so follow-up sessions keep using the same provider/model settings.
  • Image file @mentions: You can mention images in your workspace to give the model visual context directly from chat.
  • Headless Roo Code (CLI + VS Code shim): Run Roo Code in a headless environment with a basic CLI, plus an installer and an option to use the CLI for evals.
  • Debug proxy routing: Adds debug-mode proxy routing to help troubleshoot API calls.

QOL Improvements​

  • BRRR naming update: Renames YOLO to BRRR.
  • Smarter file @mention search: Filters file @mention results using .rooignore.
  • Better tooling docs: Improves the native read_file tool description and examples.
  • Web evals usability: Remembers your last model selection in web evals and adds an evals skill.

Bug Fixes​

  • Fixes PowerShell ENOENT issues on Windows.
  • Fixes shell-aware command chaining examples for Windows.
  • Fixes tool-result preservation/deduplication issues that could lead to API errors.
  • Fixes issues around tool protocol UI and provider configuration details.
