Gemini CLI v0.63.0 focuses primarily on stability and robustness improvements across various core components. A significant enhancement is the enablement of autonomous plan execution in non-interactive mode, allowing for more flexible automation workflows without direct user intervention. Several critical fixes address potential disruptions: a retry progress indicator now displays during connection recovery, improving user feedback during network issues. The CLI also now correctly distinguishes between missing and malformed MCP enablement configurations, preventing misdiagnoses. Input handling has been made more resilient by restoring paused stdin after capability detection, ensuring smooth user interaction. Core agent loops benefit from optimized memory lifecycle and bounded tool output sizes, which should lead to more stable and efficient long-running operations. Temporary directories created during background shell execution are now reliably cleaned up, preventing resource leaks. ACP sessions are resolved before config initialization, and same-minute filename collisions are avoided, enhancing session management. Policy redirection gates, path validation, and workflow parsing have been aligned for more consistent and secure policy enforcement. Authentication stability is improved by preventing infinite auth loops caused by file contention, headless keyring issues, and supervisor state drops. Finally, tool output truncation logic has been refined to disable truncation when `maxChars` is less than or equal to 0, providing more control over output display. This release is recommended for all users to benefit from increased stability and improved automation capabilities.
