持续追踪核心框架、最新模型规格与重要系统接口的更新迭代轨迹。

2.1.218

2.1.218

- Changed `/code-review` to run as a background subagent, so review work no longer fills your conversation and keeps stacked slash commands as its review target - Added screen-reader announcements of deleted text for word and line deletions (`Option+Delete`, `Ctrl+W`, `Cmd+Backspace`, `Ctrl+U`, `Ctrl+K`) in `--ax-screen-reader` mode - Fixed Windows paths with `\u`-prefixed segments (like `C:\Users\unicorn`) being corrupted into CJK characters in tool inputs, which made those files inaccessible - Fixed the left arrow key discarding the conversation with no undo: presses right after editing now ...

2.1.217

- Added emoji shortcode autocomplete in the prompt input: type `:heart:` to insert ❤️, or `:hea` for suggestions — disable with the `emojiCompletionEnabled` setting - Added warnings when transcript writes are failing (e.g. disk full) or when session saving is off due to an inherited environment variable, instead of losing transcripts silently - Fixed a memory leak where truncated MCP tool outputs kept the full untruncated result in memory for the rest of the session - Fixed Windows auto-update failures that could leave `claude.exe` missing; failed updates now restore the preserved executable a...

2.1.216

- Added `sandbox.filesystem.disabled` setting to skip filesystem isolation while keeping network egress control - Fixed a slowdown in long sessions where message normalization cost grew quadratically with the number of turns, causing multi-second stalls and slow resumes - Fixed auto mode denying commands with "HTTP 401" classifier errors after the OAuth token expired or rotated mid-session - Fixed AskUserQuestion telling Claude to continue even when your answer asked it to wait or explain first — free-text answers now get neutral wording - Fixed Claude Code on the web re-asking the same questi...

- Claude no longer runs the `/verify` and `/code-review` skills on its own; invoke them with `/verify` or `/code-review` when you want them

2.1.212

- `/fork` now copies your conversation into a new background session (its own row in `claude agents`) while you keep working; the in-session subagent it used to launch is now `/subtask` - Added `claude auto-mode reset` to restore the default auto-mode configuration, with a confirmation prompt (pass `--yes` to skip) - Added a session-wide limit on WebSearch tool calls (default 200, tunable via `CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION`) to stop runaway search loops - Added a per-session cap on subagent spawns (default 200, override with `CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION`) to stop runaway d...

2.1.211

- Added `--forward-subagent-text` flag and `CLAUDE_CODE_FORWARD_SUBAGENT_TEXT` environment variable to include subagent text and thinking in stream-json output - Fixed permission previews relayed to chat channels not neutralizing bidirectional-override, zero-width, and look-alike quote characters, so tool inputs cannot visually alter the approval message - Fixed auto mode overriding a PreToolUse hook's `ask` decision for unsandboxed Bash — a hook `ask` now floors the decision at a prompt - Fixed parallel Claude Code sessions all logging out simultaneously after wake-from-sleep when many sessio...

2.1.210

- Added a live elapsed-time counter to the collapsed tool summary line so long-running tool calls visibly tick instead of looking stuck - Added a startup warning for `Write(path)`, `NotebookEdit(path)`, and `Glob(path)` permission rules — use `Edit(path)` or `Read(path)` instead - Fixed `isolation: 'worktree'` subagents being able to run git-mutating commands against the main repo checkout instead of their own isolated worktree - Fixed the `ultracode` keyword opt-in firing on non-human-originated input such as webhook payloads and relayed PR comments - Fixed a rendered text fragment leaking in...

- Added screen reader mode: opt-in plain-text rendering for screen reader users. Run `claude --ax-screen-reader`, set CLAUDE_AX_SCREEN_READER=1, or add "axScreenReader": true to settings. - Added `vimInsertModeRemaps` setting: map two-key insert-mode sequences like `jj` to Escape in vim mode - Added `CLAUDE_CODE_PROCESS_WRAPPER`: agent view and the background service now honor a corporate launcher by running every Claude Code self-spawn through a required wrapper executable - Added mouse-click support for multi-select menus and "Other" input rows in fullscreen mode - Fixed fast mode staying of...

2.1.207

- Auto mode is now available without `CLAUDE_CODE_ENABLE_AUTO_MODE` opt-in on Bedrock, Vertex AI, and Foundry; disable via `disableAutoMode` in settings - Fixed the terminal freezing and keystrokes lagging while streaming responses containing very long lists, tables, paragraphs, or code blocks - Fixed remote managed settings from a non-interactive run (`claude -p`, the SDK) being permanently recorded as consented without ever showing the security consent dialog - Fixed spurious prompt-injection warnings triggered by benign system-generated conversation updates - Fixed the auto-updater overwrit...

2.1.203

- Added a warning when your login is about to expire, so you can re-authenticate before background sessions are interrupted - Added a grey ⏸ badge to the footer when in manual permission mode, making the active mode always visible - Added the session's additional working directories to MCP `roots/list`, with `notifications/roots/list_changed` sent when the set changes - Fixed opening or switching background agent sessions on macOS stalling for 15–20 seconds due to a false low-memory detection (regression in 2.1.196) - Fixed background sessions becoming permanently unresponsive to attach, repli...

2.1.202

- Added a "Dynamic workflow size" setting in `/config` for controlling how large Claude generally makes dynamic workflows (small/medium/large agent counts) — an advisory guideline, not an enforced cap - Added `workflow.run_id` and `workflow.name` OpenTelemetry attributes to telemetry emitted by workflow-spawned agents, so a workflow run's activity can be reconstructed from OTel data - Fixed a crash in the inline Ctrl+R history search when accepting or cancelling while the search was still scanning the history file - Fixed `/rename` on background sessions being reverted when the job restarts, w...
