# Preview release: v0.33.0-preview.4

Released: March 06, 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

- **Plan Mode Enhancements**: Added support for annotating plans with feedback
  for iteration, enabling built-in research subagents in plan mode, and a new
  `copy` subcommand.
- **Agent and Skill Improvements**: Introduced the new `github-issue-creator`
  skill, implemented HTTP authentication support for A2A remote agents, and
  added support for authenticated A2A agent card discovery.
- **CLI UX/UI Updates**: Redesigned the header to be compact with an ASCII icon,
  inverted the context window display to show usage, and directly indicate auth
  required state for agents.
- **Core and ACP Enhancements**: Implemented slash command handling in ACP (for
  `/memory`, `/init`, `/extensions`, and `/restore`), added a set models
  interface to ACP, and centralized `read_file` limits while truncating large
  MCP tool output.
