Claude Code v2.1.176: Language-Aware Sessions, Bedrock Credential Caching, and Dozens of Fixes

Claude Code v2.1.176 is out, bringing language-aware session titles, better Bedrock credential caching, and a large batch of fixes — especially for Remote Control, model enforcement, and tmux clipboard behavior.

New Features

• Language-aware session titles: Session titles are now generated in the language of the conversation. You can pin a specific language via the language setting.
• Footer link badges via regex: New footerLinksRegexes setting lets you add regex-matched link badges to the footer row. Configurable via user or managed settings.
• Improved Bedrock credential caching: Credentials from awsCredentialExport are now cached until their Expiration time, instead of a fixed 1-hour window. This reduces unnecessary re-authentication.

Model and Enforcement Fixes

• Fixed availableModels enforcement: Alias model picks could previously be redirected to a blocked model via ANTHROPIC_DEFAULT_*_MODEL environment variables. This is now enforced correctly.
• /fast now refuses to toggle if it would switch to a model outside the allowlist.
• Auto mode fallback for Fable 5: Organizations without Opus 4.8 enabled no longer break auto mode. The classifier now falls back to the best available Opus model instead of failing.

Hooks and Sandbox

• Fix hook if conditions for Read/Edit/Write tool paths: Patterns like Edit(src/**), Read(~/.ssh/**), and Read(.env) now match correctly.
• Linux sandbox: Fixed a crash when .claude/settings.json is a symlink with an absolute target.

Clipboard and Terminal

• /copy and mouse-selection copy now work inside tmux over SSH — populating the system clipboard. Previously they failed to reach the clipboard.
• tmux paste buffer now loads correctly on versions older than 3.2.

Remote Control

• Fixed silent model switching when connecting from web/mobile.
• Disconnect notifications now show a human-readable reason instead of a bare numeric code.
• Connection failures no longer add a duplicate line to the conversation transcript.
• Fixed sessions not disconnecting when signing into a different account.

Git and Worktree

• /cd and worktree moves no longer leave the session reporting the previous directory's git branch.

Background Sessions and Agents

• Pressing back in one agent window no longer detaches other windows attached to the same session.
• Fixed backgrounded sessions showing "Working" forever when /bg mid-turn had nothing left to continue.
• Background agent search by PR URL now works — PRs opened during scheduled wakeups or while a job was blocked appear in claude agents search.
• Fixed the agents view input showing no text cursor on Windows.
• claude --bg -cn <name> now correctly seeds the session name.
• Windows network paths in persisted state are neutralized before respawn.
• Malformed resume IDs from corrupted state files are now rejected instead of causing crashes.
• Fixed the Windows background-service daemon not starting when ~/.claude/daemon has the ReadOnly attribute set.

Cloud Sessions and Daemon

• Fixed cloud sessions failing with "Could not resolve authentication method" when idle for too long before being claimed.
• Background sessions now show clearer guidance when a window left open across an auto-update can't submit a reply, and claude daemon status explains version-skew behavior.

As always, update via the launcher or download from the releases page.
