Roo Code 3.19 Release Notes (2025-06-09)

This release series focuses on streamlining the user interface with intelligent context condensing enabled by default, improved mode organization, enhanced file protection, experimental multi-file reading capabilities, and numerous quality-of-life improvements.

Provider Updates​

  • OpenRouter Latency: Replaced explicit caching with implicit caching for Gemini models via OpenRouter to significantly reduce latency (#4488)

  • Bedrock: Improved model information detection for custom Bedrock ARNs, ensuring better compatibility (thanks adamhill!)

QOL Improvements​

  • Fix reading PDF, DOCX, and IPYNB files in read_file tool: Ensures reliable reading of these file types (thanks samhvw8!)
  • History Preview: Buttons in the history preview now fade when there is no interaction, providing a cleaner UI (thanks samhvw8!) (#4458)

Bug Fixes​

  • Mermaid Diagrams: Fixed Content Security Policy (CSP) errors for Mermaid diagrams by implementing an enhanced bundling strategy (thanks KJ7LNW!)
  • LiteLLM Provider: Fixed a bug that caused an error when the LiteLLM provider URL contained a trailing slash (thanks kcwhite!) (#4275)

Documentation Updates​

  • Concurrent File Reads: Clarified that the default concurrent file read limit is 15, not the maximum (thanks olearycrew!) (#4474)

Misc Improvements​

  • OpenAI Compatible Embedder: Added a new embedder for codebase indexing that is compatible with the OpenAI API, expanding options for local and custom embedding models (thanks SannidhyaSah!)
  • Enforce codebase_search as primary tool: Roo Code now always uses codebase_search as the first step for code understanding tasks, improving accuracy and consistency (thanks hannesrudolph!)
  • Build Scripts: Removed unnecessary npx usage from some npm scripts (thanks user202729!) (#4003)
  • Storybook: We've removed unused Storybook components and dependencies to reduce the bundle size. (#4517)
  • ESLint: We've added a data-testid ESLint rule to improve our testing standards (thanks elianiva!). (#4505)
  • Dependencies: We've updated our development dependencies, including eslint, knip, @types/node, i18next, fast-xml-parser, and @google/genai.
  • CI: We've improved our CI infrastructure with GitHub Actions and Blacksmith runner migrations. (#4472, #4507)
