# Preview release: v0.44.0-preview.0

Released: May 22, 2026

Our preview release includes the latest, new, and experimental features. 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.
