The latest Claude Code update brings version 2.1.153 to developers with 36 command-line interface changes.
Anthropic released this version to address performance issues, security vulnerabilities, and terminal rendering bugs. Notably, the release occurs just one day after the previous version.
Developers can now use the skipLfs option within the Git and GitHub plugin marketplace sources. Consequently, this option skips Git LFS downloads during clone and update processes to reduce bandwidth. Meanwhile, the update resolves a credential exposure risk in custom API gateways.
Security Enhancements in the Release
Specifically, the custom API gateway now uses its own token instead of the user’s Anthropic OAuth credential. This change prevents accidental credential exposure during active sessions. In addition, the startup notifications for MCP servers and connectors are now combined into a single message.
On macOS, background agents now appear as “Claude Code” in the Privacy and Security settings. Furthermore, these agents retain their permission grants across software upgrades. These changes aim to improve the overall cybersecurity posture of the tool.
Key Features of the Claude Code update
The **Claude Code update** also introduces a one-time notice when global npm installations cannot auto-update. Users can run the doctor command to view a list of available fixes. Additionally, the doctor command now displays the result of the last update attempt.
For terminal interactions, the grep tool description now specifies that it is powered by ripgrep. The system prompts developers to prefer this tool for search tasks. Moreover, the update adds a new empty model option to the CLI surface.
Bug Fixes and Performance Improvements
The release addresses excessive memory usage when users resume sessions by transcript file paths. Previously, this action consumed multiple gigabytes of memory on machines with many stored sessions. Furthermore, the update fixes a hang where the CLI failed to exit when stdin closed without EOF.
Windows users receive an update rollback fix that restores the original executable if an update fails. Additionally, the installer no longer reports a successful installation when the process actually fails in PowerShell. These fixes resolve critical platform-specific issues.
Future Outlook and Developer Impact
This release demonstrates the rapid development cycle of developer tools utilizing artificial intelligence. By addressing 36 distinct issues, the update refines the command-line experience for engineering workflows. Developers can install the latest version through their configured release channels.
As apps and software continue to integrate deeper terminal capabilities, security remains a primary focus. The separation of gateway tokens represents a necessary step in securing local development environments. Consequently, users are encouraged to run the doctor command to verify their installation status.
