This release may not be as stable as our [latest weekly release](latest.md). To install the preview release: ``` npm install -g @google/gemini-cli@preview ``` ## Highlights - **Simplified Modes:** Merged existing Auto modes into a single, unified Auto mode for a more streamlined user experience. - **Enhanced Agent Registration:** Improved agent registration logic to prioritize project-specific agents using a first-wins strategy. - **New Developer Skills:** Introduced `agent-tui` and `tui-tester` skills to empower developers with better terminal UI testing and automation capabilities. - **Expanded Editor Support:** Added support for Sublime Text and Emacs Client, providing more flexibility for external editing tasks. - **Session Management:** Added new session invocation types (`LocalSessionInvocation`, `RemoteSessionInvocation`) and improved context recovery across sessions. ## What's Changed -
