Google published Gemini CLI 0.66.0 and 0.67.0-preview.0 on October 27. They are separate release channels, combined in one update here.
Stable 0.66
The stable release checks the active binary during updates to avoid reporting success when a different executable shadows it on PATH. It also adjusts terminal rendering, preserves user-level Git configuration and supports opt-in private-network endpoints for MCP OAuth flows.
What remains preview-only
The 0.67 preview bridges the IDE companion into container sandboxes over exec stdio and adds a models command and list-models flag. Cancellation handling and MCP permission metadata also change.
Do not attribute these preview capabilities to the stable release. A CLI version is not a new Gemini model, and the release notes do not establish universal free hosted-model access or performance improvements.
