Preview release: v0.33.0-preview.1

Released: March 04, 2026

Our preview release includes the latest, new, and experimental features. This release may not be as stable as our latest weekly release.

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.
