[Release] anthropics/claude-code v2.1.176: v2.1.176

Claude Code v2.1.176 introduces multilingual session titles, improved credential caching for AWS Bedrock, and enhanced footer link configuration via regex patterns. The release includes critical fixes for model enforcement, auto mode fallback logic, file path matching in hooks, and clipboard operations in tmux/SSH environments. Additionally, Remote Control stability, background session management, and Windows daemon initialization have been significantly improved.

Key Points

• •Session titles now auto-generate in the conversation's language; use `language` setting to pin a specific language
• •New `footerLinksRegexes` setting enables regex-matched link badges in footer rows, configurable via user or managed settings
• •AWS Bedrock credentials from `awsCredentialExport` now cache until their `Expiration` time instead of fixed 1-hour expiry
• •Model allowlist enforcement strengthened: alias model picks cannot redirect to blocked models via `ANTHROPIC_DEFAULT_*_MODEL` env vars; `/fast` refuses toggles outside allowlist
• •Auto mode fallback improved: classifier now falls back to best available Opus model when Opus 4.8 unavailable (fixes Fable 5 failures)
• •Hook `if` conditions fixed for Read/Edit/Write tool paths: patterns like `Edit(src/**)`, `Read(~/.ssh/**)`, `Read(.env)` now match correctly
• •Linux sandbox symlink handling fixed: `.claude/settings.json` as absolute-target symlink no longer causes startup failures
• •Clipboard operations in tmux over SSH fixed: `/copy` and mouse-selection copy now reach system clipboard; tmux paste buffer loads on v3.2+
• •Remote Control stability enhanced: prevents silent model switching, shows human-readable disconnect reasons, handles account sign-in properly
• •Background session improvements: clearer guidance on auto-update conflicts, better respawn error handling, Windows network path neutralization, daemon startup with ReadOnly attributes
