Claude Code v2.1.153 Release Notes

The Claude Code team has released version 2.1.153, packed with useful improvements for power users managing complex AI workflows. This update focuses on enhancing Git operations, streamlining update management, and fixing several critical issues that improve overall stability.

What’s New

Git LFS Performance Optimization

A new skipLfs option has been added to github/git plugin marketplace sources, allowing you to skip Git LFS downloads during clone and update operations. This can significantly speed up repository operations when LFS files aren’t needed.

Improved Update Management

Claude Code now displays a one-time notice when your npm global installation can’t auto-update, with /doctor providing specific fixes. The claude doctor command also shows the result of your last update attempt, making troubleshooting easier.

Enhanced Terminal Integration

Status line commands now receive COLUMNS and LINES environment variables, enabling scripts to dynamically size their output to match your terminal width for better readability.

Agent Management Improvements

Autocomplete in claude agents dispatch input now suggests native slash commands and bundled skills alongside project skills
PR column displays PR #N for single PRs or N PRs for multiple pull requests
macOS background agents now appear as “Claude Code” in Privacy & Security settings and retain permissions across upgrades

Authentication Streamlining

The previously separate “needs authentication” notifications for MCP servers and connectors have been combined into a single, cleaner message.

Critical Bug Fixes

Fixed stateful MCP servers without optional GET SSE stream from reconnect-looping
Resolved regression where custom API gateways received incorrect OAuth credentials
Fixed subagent MCP server configuration inheritance issues
Corrected Windows PowerShell installer false success reporting
Resolved excessive memory usage when resuming sessions by transcript file path
Fixed CLI hanging when stdin was closed without EOF in stream-json mode
Multiple background session and file handling improvements

How to Update

Update Claude Code using your preferred installation method:

# npm installation
npm update -g claude-code

# or use the built-in update command
claude update

After updating, run claude doctor to verify your installation and check for any configuration issues.
