Claude Code v2.1.176: Bedrock Credential Caching & 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.
