The Claude Code development team has released version 2.1.176, delivering significant improvements to internationalization, credential management, and background session reliability. This update focuses on enhancing the user experience across different languages and platforms while fixing numerous edge cases that affected power users.

What’s New

Multilingual Session Titles

Session titles are now automatically generated in the language of your conversation. You can pin a specific language by setting the language configuration option, giving you full control over how your sessions are organized and displayed.

The new footerLinksRegexes setting allows you to add regex-matched link badges to the footer row. This feature is configurable through both user and managed settings, providing flexibility for team environments and personal workflows.

Improved AWS Bedrock Integration

Bedrock credential caching has been significantly enhanced. Credentials from awsCredentialExport are now cached until their actual Expiration time instead of a fixed 1-hour limit, reducing unnecessary authentication requests and improving performance.

Model Access Security

The availableModels enforcement has been strengthened. Alias model selections can no longer bypass blocked models through ANTHROPIC_DEFAULT_*_MODEL environment variables, and the /fast command now properly refuses to toggle when it would switch to a model outside the allowlist.

Auto Mode Fallback Improvements

Auto mode now gracefully handles organizations without Opus 4.8 enabled. The classifier intelligently falls back to the best available Opus model, ensuring Fable 5 compatibility across different organizational configurations.

Comprehensive Bug Fixes

This release addresses numerous issues including:

  • File path matching for Read/Edit/Write tool hooks
  • Linux sandbox startup with symlinked configuration files
  • Clipboard operations in tmux over SSH environments
  • Remote Control session management and disconnect notifications
  • Background session state persistence and respawn reliability
  • Windows-specific path handling and service daemon startup
