- Fixed an issue when using Opus 4.8 where thinking blocks were modified, leading to API errors.

- Opus 4.8 is here! Now defaults to high effort · /effort xhigh for your hardest tasks - Introducing dynamic workflows: ask Claude to create a workflow and it orchestrates work across tens to hundreds of agents in the background, so you can take on larger, more complex tasks.

- Fixed the Bash tool returning exit code 127 on every command for some users (a regression introduced in 2.1.147)

- Pinned background sessions (`Ctrl+T` in `claude agents`) now stay alive when idle, are restarted in place to apply Claude Code updates, and are shed under memory pressure only after non-pinned sessions - Renamed `/simplify` to `/code-review`. It now reports correctness bugs at a chosen effort level (e.g., `/code-review high`); pass `--comment` to post findings as inline GitHub PR comments. The old cleanup-and-fix behavior has been removed - Improved auto-updater: retries transient network failures, reports specific error categories and OS error codes on failure, and shows the current version...

- Improved Agent tool `subagent_type` matching to accept case- and separator-insensitive values (e.g. `"Code Reviewer"` resolves to `code-reviewer`) - Updated agent color palette - Fixed `/goal` silently hanging when `disableAllHooks` or `allowManagedHooksOnly` is set — now shows a clear message instead of an indicator that never resolves - Fixed a regression in settings hot-reload where symlinked settings files caused misattributed change events and spurious `ConfigChange` hooks - Fixed `claude --bg` failing with "connection dropped mid-request" when the background service was about to idle-e...

- Added `worktree.baseRef` setting (`fresh` | `head`) to choose whether `--worktree`, `EnterWorktree`, and agent-isolation worktrees branch from `origin/ ` or local `HEAD`. **Note:** the default `fresh` changes `EnterWorktree`'s base back to `origin/ ` (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 S...
