Roo Code 3.20 Release Notes (2025-06-12)

This release introduces the experimental Marketplace for extensions and modes, concurrent file edits and reads, and numerous other improvements and bug fixes.

MCP & Mode Marketplace (experimental)​

We've introduced an experimental Marketplace for discovering and installing community-contributed extensions and modes. This feature allows you to:

  • Browse and search for new modes and MCP servers
  • Install items at project or global scope
  • Manage installations directly from the Marketplace view

To enable: Open Roo Code settings (gear icon) → Experimental Settings → Enable "Marketplace"

(thanks Smartsheet-JB-Brown, elianiva, monkeyDluffy6017, NamesMT, daniel-lxs, and more!) (#4538, #4604)

Concurrent Edits (aka multi-file)(experimental)​

You can now perform edits across multiple files at once, dramatically speeding up refactoring and multi-file changes. Instead of approving each file edit individually, you can review and approve all changes at once through a unified batch approval interface. Check out our concurrent file edits documentation for more details.

To enable: Open Roo Code settings (gear icon) → Experimental Settings → Enable "Enable multi-file edits"

(thanks samhvw8!) (#4608)

Concurrent Reads (aka multi-file)​

The setting for concurrent reads has been moved to the context settings, with a default of 5. This feature allows Roo to read multiple files from your workspace in a single step, significantly improving efficiency when working on tasks that require context from several files. Learn more in our concurrent file reads documentation.

Prompt History​

Navigate your prompt history with a terminal-like experience using the arrow keys. This feature makes it easy to reuse and refine previous prompts, whether from your current conversation or past tasks. See our keyboard shortcuts documentation for usage details.
