Release Notes
- 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 $CLAUDEEFFORT environment variable, and Bash tool commands can read $CLAUDEEFFORT
- 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 / NOPROXY / 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
