| 1 | +# Roo Code 3.20 Release Notes (2025-06-12) |
| 2 | + |
| 3 | +This release introduces the experimental Marketplace for extensions and modes, multi-file edits, and numerous other improvements and bug fixes. |
| 4 | + |
| 5 | +## MCP & Mode Marketplace (experimental) |
| 6 | + |
| 7 | +We've introduced an experimental [Marketplace](/features/marketplace) for discovering and installing community-contributed extensions and modes. This feature allows you to browse, search, and install new modes and MCP servers, extending Roo Code's functionality with community-driven components. You can install items at a project or global scope, and manage them directly from the Marketplace view. (thanks Smartsheet-JB-Brown, elianiva, monkeyDluffy6017, NamesMT, daniel-lxs, and more!) ([#4538](https://github.com/RooCodeInc/Roo-Code/pull/4538), [#4604](https://github.com/RooCodeInc/Roo-Code/pull/4604)). |
| 8 | + |
| 9 | +## Concurrent Edits (aka multi-file)(experimental) |
| 10 | + |
| 11 | +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. For more information, see the [documentation](/features/experimental/concurrent-file-edits). (thanks samhvw8!) ([#4608](https://github.com/RooCodeInc/Roo-Code/pull/4608)). |
| 12 | + |
| 13 | +## Concurrent Reads (aka multi-file) |
| 14 | + |
| 15 | +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. For more information, see the [documentation](/features/concurrent-file-reads). ([#4597](https://github.com/RooCodeInc/Roo-Code/pull/4597)). |
| 16 | + |
| 17 | +## Prompt History |
| 18 | + |
| 19 | +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. For more information, see the [documentation](/features/keyboard-shortcuts#command-line-style-prompt-history-navigation). ([#4580](https://github.com/RooCodeInc/Roo-Code/pull/4580)). |
