+new 3

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

~changed 7

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
