Roo Code 3.14.0 Release Notes (2025-04-23)

This release introduces Gemini prompt caching, improves several tools, and includes numerous bug fixes and enhancements across the extension.

Apply Diff and Other Major File Edit Improvements

• Improve apply_diff to work better with Google Gemini 2.5 and other models
• Automatically close files opened by edit tools (apply_diff, insert_content, search_and_replace, write_to_file) after changes are approved. This prevents cluttering the editor with files opened by Roo and helps clarify context by only showing files intentionally opened by the user.
• Added the search_and_replace tool. This tool finds and replaces text within a file using literal strings or regex patterns, optionally within specific line ranges (thanks samhvw8!).
• Added the insert_content tool. This tool adds new lines into a file at a specific location or the end, without modifying existing content (thanks samhvw8!).
• Deprecated the append_to_file tool in favor of insert_content (use line: 0).
• Correctly revert changes and suggest alternative tools when write_to_file fails on a missing line count
• Better progress indicator for apply_diff tools (thanks qdaxb!)
• Ensure user feedback is added to conversation history even during API errors (thanks System233!).
• Prevent redundant 'TASK RESUMPTION' prompts from appearing when resuming a task (thanks System233!).
• Fix issue where error messages sometimes didn't display after cancelling an API request (thanks System233!).
• Preserve editor state and prevent tab unpinning during diffs (thanks seedlord!)

Context Mentions

• Use material icons for files and folders in mentions (thanks elianiva!)

• Improvements to icon rendering on Linux (thanks elianiva!)

• Better handling of aftercursor content in context mentions (thanks elianiva!)

  

Footgun Prompting

• Context Variables: Added the ability to interpolate context variables ({{workspace}}, {{mode}}, {{language}}, {{shell}}, {{operatingSystem}}) into custom system prompt override files, allowing for more dynamic prompts (thanks daniel-lxs!). See the Footgun Prompting documentation for details.

• Override Warning: Roo Code now displays a warning indicator in the chat input when a system prompt override is active for the current mode.

  

MCP Tweaks

• Support injecting environment variables in MCP config (thanks NamesMT!)
• Fix MCP hub error when dragging extension to another sidebar
• Improve display of long MCP tool arguments
