Claude Code v2.1.98

What's changed

• Added interactive Google Vertex AI setup wizard accessible from the login screen when selecting "3rd-party platform", guiding you through GCP authentication, project and region configuration, credential verification, and model pinning
• Added CLAUDE_CODE_PERFORCE_MODE env var: when set, Edit/Write/NotebookEdit fail on read-only files with a p4 edit hint instead of silently overwriting them
• Added Monitor tool for streaming events from background scripts
• Added subprocess sandboxing with PID namespace isolation on Linux when CLAUDE_CODE_SUBPROCESS_ENV_SCRUB is set, and CLAUDE_CODE_SCRIPT_CAPS env var to limit per-session script invocations
• Added --exclude-dynamic-system-prompt-sections flag to print mode for improved cross-user prompt caching
• Added workspace.git_worktree to the status line JSON input, set whenever the current directory is inside a linked git worktree
• Added W3C TRACEPARENT env var to Bash tool subprocesses when OTEL tracing is enabled, so child-process spans correctly parent to Claude Code's trace tree
• LSP: Claude Code now identifies itself to language servers via clientInfo in the initialize request
• Fixed a Bash tool permission bypass where a backslash-escaped flag could be auto-allowed as read-only and lead to arbitrary code execution
• Fixed compound Bash commands bypassing forced permission prompts for safety checks and explicit ask rules in auto and bypass-permissions modes
• Fixed read-only commands with env-var prefixes not prompting unless the var is known-safe (LANG, TZ, NO_COLOR, etc.)
• Fixed redirects to /dev/tcp/... or /dev/udp/... not prompting instead of auto-allowing
• Fixed stalled streaming responses timing out instead of falling back to non-streaming mode
• Fixed 429 retries burning all attempts in ~13s when the server returns a small Retry-After — exponential backoff now applies as a minimum
• Fixed MCP OAuth oauth.authServerMetadataUrl config override not being honored on token refresh after restart, affecting ADFS and similar IdPs
• Fixed capital letters being dropped to lowercase on xterm and VS Code integrated terminal when the kitty keyboard protocol is active
• Fixed macOS text replacements deleting the trigger word instead of inserting the substitution
• Fixed --dangerously-skip-permissions being silently downgraded to accept-edits mode after approving a write to a protected path via Bash
• Fixed managed-settings allow rules remaining active after an admin removed them, until process restart
• Fixed permissions.additionalDirectories changes not applying mid-session — removed directories lose access immediately and added ones work without restart
• Fixed removing a directory from additionalDirectories revoking access to the same directory passed via --add-dir
• Fixed Bash(cmd:*) and Bash(git commit *) wildcard permission rules failing to match commands with extra spaces or tabs
• Fixed Bash(...) deny rules being downgraded to a prompt for piped commands that mix cd with other segments
• Fixed false Bash permission prompts for cut -d /, paste -d /, column -s /, awk '{print $1}' file, and filenames containing %
• Fixed permission rules with names matching JavaScript prototype properties (e.g. toString) causing settings.json to be silently ignored
• Fixed agent team members not inheriting the leader's permission mode when using --dangerously-skip-permissions
• Fixed a crash in fullscreen mode when hovering over MCP tool results
• Fixed copying wrapped URLs in fullscreen mode inserting spaces at line breaks
• Fixed file-edit diffs disappearing from the UI on --resume when the edited file was larger than 10KB
• Fixed several /resume picker issues: --resume <name> opening uneditable, filter reload wiping search state, empty list swallowing arrow keys, cross-project staleness, and transient task-status text replacing conversation summaries
• Fixed /export not honoring absolute paths and ~,
