Roo Code 3.19.6 Release Notes (2025-06-09)

This release introduces implicit caching for Gemini models to reduce latency, clarifies the concurrent file read limit, and includes several bug fixes and quality-of-life improvements.

Provider Updates

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

QOL Improvements

• History Preview: Buttons in the history preview now fade when there is no interaction, providing a cleaner UI (thanks samhvw8!) (#4458)

Bug Fixes

• MCP Server Management: Fixed a bug where the MCP server list would not update correctly after changes (like adding or deleting servers) without a full extension reload. The manual refresh button and automatic refresh on configuration changes now work reliably. (thanks taylorwilsdon!) (#4267)
• LiteLLM Provider: Fixed a bug that caused an error when the LiteLLM provider URL contained a trailing slash (thanks kcwhite!) (#4275)
• Copy Button: Fixed an issue with the copy button logic (thanks samhvw8!) (#4458)

Documentation Updates

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

Misc Improvements

• Build Scripts: Removed unnecessary npx usage from some npm scripts (thanks user202729!) (#4003)
