Mar 1, 2026March 2026: Delivered security-focused sandboxing improvements, UX and reliability enhancements for google-gemini/gemini-cli. Key features include direct extension installation from the Registry View and enhanced MCP server listing with disabled/blocked status. Implemented Linux sandboxing using Bubblewrap and seccomp to strengthen process isolation; added governance files write-protection inside the sandbox and blocked access to secret files (.env) at the workspace root. Resolved a Plan Mode deadlock by ensuring the plans directory exists to support sandboxed file operations. These changes collectively improve security, stability, and user experience, reducing risk while enabling safer, more predictable workflows.
