Noteworthy Changes

Task Timeline Visualization

Available in: v4.39.0 | Contributor: @hassoncs
Enhanced in: v4.43.0

Finally—a visual way to navigate your chat history. The timeline displays your conversation flow and allows you to click to jump to specific moments. It’s perfect for understanding what happened during long coding sessions.

It’s enabled by default, but you can disable it in Display Settings. In v4.43.0, we added colorful gutters that connect timeline events to actual chat messages.

Workspace Root Environment Variable

Available in: v4.40.0 | Contributor: @hassoncs

Terminal sessions now automatically include $WORKSPACE_ROOT pointing to your current workspace. No more navigating back to root for every command:

cd $WORKSPACE_ROOT && npx jest

Especially useful in deeply nested directories or multi-workspace setups.

Claude Code Provider Support

Available in: v4.44.0 | Contributor: @kevinvandijk | via Roo, inspired by Cline

Much requested direct integration with Claude Code!

Gemini CLI Provider Support

Available in: v4.44.0 | Contributor: @kevinvandijk | via Roo, inspired by Cline

Direct integration with Google's Gemini CLI for seamless local-to-cloud AI workflows.

Cerebras API Provider

Available in: v4.39.0 | Contributor: @markijbema | via Cline

Added support for Cerebras' lightning-fast inference API. Because sometimes you need your AI responses yesterday.

Developer Experience Improvements

Multi-Language Localization

Available in: v4.43.0 | Contributor: @chrarnoldus

We had a massive wave of new users from the Philippines and Thailand! Of course, added support for them, as well as for the Ukrainian, Czech, Greek, and Swedish languages. Because good tools should speak your language!

Is that your native language? Help the community by reading through the files, and let us know if we did well. We don’t have native speakers in the core team!

Context Window Progress Bar Enhancement

Available in: v4.43.0 | Contributor: @hassoncs

The progress bar now turns red when you're approaching token limits. No more mysterious context window errors—you'll see them coming.

Mermaid Diagram Auto-Fix

Available in: v4.43.1 | Contributor: @markijbema

Broken Mermaid diagram? Hit the fix button and let AI correct the syntax errors. Because debugging diagram syntax is nobody's favorite hobby.

Enhanced Multi-File Operations

Available in: v4.39.0 | Contributors: @samhvw8, @daniel-lxs | via Roo Code

• Experimental multi-file edits for complex refactoring

• Better diff error handling and UI feedback

• Fixed multi-file diff operations with proper start line handling

Copy Prompt Button
Available in: v4.45.0 | Contributors: @Juice10 | via Community @vultrnerd

A convenient way to copy your prompt to the clipboard!
