• Gateway model discovery is now opt-in. If you relied on the /model picker listing your gateway's models (automatic since 2.1.126), set CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1 to restore it (more below).

• Ctrl+R history search scopes to all projects again. Press Ctrl+S inside the picker to narrow by project or session, reversing the 2.1.124 default (more below).

• Plugin themes and monitors must move under an experimental key in the manifest. Top-level declarations still work but claude plugin validate now warns.

• skillOverrides setting now works: control which skills the model sees. Set individual skills to off, user-invocable-only, or name-only in your settings.

New in 2.1.129

2.1.129 (May 6, 2026)

• Added --plugin-url <url> flag to fetch a plugin .zip archive from a URL for the current session
• Added CLAUDE_CODE_FORCE_SYNC_OUTPUT=1 env var to force-enable synchronized output on terminals that auto-detection misses (e.g. Emacs eat)
• Added CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE: when set on Homebrew or WinGet installations, Claude Code runs the upgrade command in the background and prompts to restart
• Plugin manifests: themes and monitors should now be declared under "experimental": { ... }. Top-level declarations still work but claude plugin validate will warn
• Gateway /v1/models discovery for the /model picker is now opt-in via CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1 (was automatic in 2.1.126-2.1.128)
• Ctrl+R history picker now defaults to searching all prompts across all projects, matching pre-2.1.124 behavior. Press Ctrl+S to narrow to the current project or session
• Third-party deployments (Bedrock, Vertex, Foundry, or ANTHROPIC_BASE_URL gateway) no longer see spinner tips pointing at first-party Anthropic surfaces
• skillOverrides setting now works: off hides from model and /, user-invocable-only hides from model only, name-only collapses description
• The claude_code.pull_request.count OTel metric now counts PRs/MRs created via MCP tools, not just shell commands
• Policy refusal error messages now include the API Request ID for easier support debugging
• Fixed API errors with unrecognized 400 status codes showing raw JSON instead of the underlying error message
• Fixed /clear not resetting the terminal tab title after a conversation
• Fixed session title chip from /rename disappearing while a permission or other dialog is active
• Fixed agent panel below the prompt being hidden when subagents are running (regression in 2.1.122)
• Fixed external-editor handoff (Ctrl+G) blanking the conversation history above the prompt
• Fixed /context dumping its rendered ASCII visualization grid into the conversation, wasting ~1.6k tokens per call
• Fixed /agents Library list arrow-key navigation: the highlighted agent now stays visible when the list exceeds the viewport
• Fixed /branch success message not including the new branch's session id for /resume
• Fixed bold headers with keycap/ZWJ/skin-tone emoji losing trailing characters in fullscreen mode
• Fixed server-managed settings policy not applying for enterprise/team users whose stored OAuth credentials lacked the user:inference scope
• Fixed OAuth refresh race after wake-from-sleep that could log out all running sessions
• Fixed 1-hour prompt cache TTL being silently downgraded to 5 minutes
• Fixed cache-miss warning appearing spuriously after /clear or compaction when changing /effort or /model
• Fixed Bash(mkdir *), Bash(touch *) and similar allow rules not being honored for in-project paths
• Fixed deniedMcpServers patterns with a *:// scheme wildcard not matching mixed-case hostnames
• Fixed harmless WebSocket warning being logged as an error in --debug during voice mode
• [VSCode] Fixed /clear not clearing the conversation context and displayed transcript
