# Claude Code 2.1.133

Captured: 2026-05-10T08:59:01.770Z

- Added `worktree.baseRef` setting (`fresh` | `head`) to choose whether `--worktree`, `EnterWorktree`, and agent-isolation worktrees branch from `origin/<default>` or local `HEAD`. **Note:** the default `fresh` changes `EnterWorktree`'s base back to `origin/<default>` (it has been local `HEAD` since 2.1.128) — set `worktree.baseRef: "head"` to keep unpushed commits in new worktrees
- Added `sandbox.bwrapPath` and `sandbox.socatPath` managed settings (Linux/WSL) to specify custom bubblewrap and socat binary locations
- Added `parentSettingsBehavior` admin-tier key (`'first-wins' | 'merge'`) to let admins opt SDK `managedSettings` (parent tier) into the policy merge
- Hooks now receive the active effort level via the `effort.level` JSON input field and the `$CLAUDE_EFFORT` environment variable, and Bash tool commands can read `$CLAUDE_EFFORT`
- Improved focus mode behavior
- Improved memory usage by releasing warm-spare background workers under memory pressure
- Fixed parallel sessions all dead-ending at 401 after a refresh-token race wiped shared credentials
- Fixed `Edit`/`Write` allow rules scoped to a drive root (`C:\`) or POSIX `/` matching incorrectly and always prompting
- Fixed an unhandled rejection (`ECOMPROMISED`) when a history or session-log file lock is compromised by clock skew or slow disk
- Fixed pressing Esc during conversation compaction showing a spurious "Error compacting conversation" notification
- Fixed `HTTP(S)_PROXY` / `NO_PROXY` / mTLS not being respected for the full MCP OAuth flow including discovery, dynamic client registration, token exchange, and token refresh
- Fixed Read/Write/Edit being denied on mapped network drives passed via `--add-dir` / SDK `additionalDirectories`
- Fixed Remote Control stop/interrupt from claude.ai not fully canceling the CLI session the same way local Esc does, causing queued messages to never advance after interrupting a stuck tool or prompt
- Fixed `/effort` in one session unexpectedly changing the effort level of other concurrent sessions, and a related issue where an IDE effort change could be silently dropped
- Fixed subagents not discovering project, user, or plugin skills via the Skill tool
- `claude --help` now lists `--remote-control` alongside `--remote-control-session-name-prefix`
- [VSCode] Fixed `claudeCode.claudeProcessWrapper` failing with "Unsupported platform" when the extension build doesn't bundle a Claude binary
