Claude Code v2.1.5 Release Notes

Claude Code v2.1.5 is now available, bringing an important environment configuration feature for users who need custom temp directory locations.

What’s New

Custom Temp Directory

This release introduces the CLAUDE_CODE_TMPDIR environment variable, allowing users to override the temp directory used for Claude Code’s internal temp files.

This feature is particularly useful for:

• Containerized environments: When running in Docker or Kubernetes and needing to write temp files to specific mount points
• Restricted systems: Environments where the default /tmp directory has size or permission limitations
• Enterprise environments: Organizations that need centralized temp file management or specific partition placement
• Development and debugging: Easy tracking and inspection of temp files generated by Claude Code

Usage

Set the environment variable to point to your desired directory:

export CLAUDE_CODE_TMPDIR=/path/to/custom/temp

Or specify it at launch time:

CLAUDE_CODE_TMPDIR=/my/temp/dir claude

How to Update

Update to Claude Code v2.1.5:

npm update -g @anthropic-ai/claude-code

Or use your preferred package manager. Restart Claude Code after updating to ensure all changes take effect.
