# Preview release: v0.51.0-preview.0
Released: July 8, 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
- **Caretaker Cloud Run Services**: Implemented a Cloud Run webhook ingestion
service and egress service skeleton to support advanced caretaker features.
- **Enhanced Security & Sandbox Hardening**: Enforced a case-insensitive
sensitive path blocklist and VS Code human-in-the-loop (HITL) checks, resolved
a directory escape vulnerability in the memory import processor, and marked
`~/.gitconfig` as read-only within the macOS sandbox.
- **Improved Thought Leakage and Escape Handling**: Resolved potential thought
leakage by stripping thinking/thought processes from scrubbed history turns,
and ensured escape sequences in string literals are correctly preserved for
modern models.
- **Robust Path & API Updates**: Enhanced defensive path resolution for
at-reference files, and updated the Vertex AI base URL configuration to
support the latest API updates.
