[ 重大突破 ] 2.1.187

2.1.187

- Added `sandbox.credentials` setting to block sandboxed commands from reading credential files and secret environment variables - Added org-configured model restrictions to the model picker, `--model`, `/model`, and `ANTHROPIC_MODEL`, with a "restricted by your organization's settings" message when a restricted model is selected - Added mouse click support to select menus (permission prompts, `/model`, `/config`, etc.) in fullscreen mode - Fixed `--resume` failing with "No conversation found" when the original `-p` run produced no model turns - Fixed `--json-schema` and workflow `agent({schem...

- The stream-stall hint now reads "Waiting for API response · will retry in …" instead of "No response from API · Retrying in …", and triggers after 20s of silence instead of 10s

2.1.183

2.1.183

- Improved auto mode safety: destructive git commands (`git reset --hard`, `git checkout -- .`, `git clean -fd`, `git stash drop`) are now blocked when you didn't ask to discard local work, `git commit --amend` is blocked when the commit wasn't made by the agent this session, and `terraform destroy`/`pulumi destroy`/`cdk destroy` are blocked unless you asked for the specific stack - Added a warning when the requested model is deprecated or automatically updated to a newer model, shown on stderr in print mode (`-p`) and now also covering models set in agent frontmatter - Added `attribution.sess...

2.1.179

- Fixed mid-stream connection drops: partial responses are now preserved instead of showing a raw error, and the spinner no longer gets stuck at "running tool" - Fixed mouse-wheel scrolling in WSL2 under Windows Terminal and VS Code (regression in 2.1.172) - Fixed a sandbox `denyRead`/`allowRead` glob over a large directory tree making the Bash tool description enormous and the session unusable on Linux - Fixed the feedback survey capturing a single-digit reply as a session rating immediately after a turn completes - Fixed the welcome screen stacking multiple promotional banners — at most one ...

[ 重大突破 ] 2.1.178

2.1.178

- Added `Tool(param:value)` syntax for permission rules to match a tool's input parameters (with `*` wildcard), e.g. `Agent(model:opus)` to block Opus subagents - Skills in nested `.claude/skills` directories now load when working on files there; on a name clash, the nested skill appears as ` : ` so both stay available - Nested `.claude/` directories: the agent, workflow, and output-style closest to the working directory now wins when names collide; project-scope workflow saves now target the closest existing `.claude/workflows/` - Improved auto mode: subagent spawns are now evaluated by the c...

2.1.176

- Session titles are now generated in the language of your conversation (set the `language` setting to pin a specific language) - Added `footerLinksRegexes` setting for regex-matched link badges in the footer row, configurable via user or managed settings - Improved Bedrock credential caching: credentials from `awsCredentialExport` are now cached until their `Expiration` instead of a fixed 1 hour - Fixed `availableModels` enforcement: alias model picks can no longer be redirected to a blocked model via `ANTHROPIC_DEFAULT_*_MODEL` environment variables, and `/fast` now refuses to toggle when it...

2.1.175

2.1.175

- Added `enforceAvailableModels` managed setting — when enabled, the `availableModels` allowlist also constrains the Default model (a Default that would resolve to a disallowed model now falls back to the first allowed model), and user or project settings can no longer widen a managed `availableModels` list

[ 重大突破 ] 2.1.174

2.1.174

- Added `wheelScrollAccelerationEnabled` setting to disable mouse-wheel scroll acceleration in fullscreen mode - Fixed the `/model` picker hiding the model family that Default resolves to — Opus now appears as its own row on Max/Team Premium/Enterprise plans, Sonnet on Pro/Team plans, and Opus on pay-as-you-go API accounts - Fixed `/model` picker showing a hardcoded Sonnet version label when `ANTHROPIC_DEFAULT_SONNET_MODEL` pins a different Sonnet - Fixed the "Fable 5 is now consuming usage credits" banner incorrectly showing for enterprise accounts with usage-based billing - Fixed Bedrock Gov...

2.1.173

2.1.173

- Fixed Fable 5 model names with a `[1m]` suffix not being normalized — Fable 5 includes 1M context by default, so the suffix is now stripped automatically - Fixed a spurious "sandbox dependencies missing" startup warning on Windows when sandbox was enabled in settings

2.1.172

- Sub-agents can now spawn their own sub-agents (up to 5 levels deep) - Amazon Bedrock now reads the AWS region from `~/.aws` config files when `AWS_REGION` isn't set, matching AWS SDK precedence; `/status` shows where the region came from - Added a search bar when browsing a marketplace's plugins in `/plugin` - Added `model` attribute to the `claude_code.lines_of_code.count` OTEL metric - Fixed sessions using 1M context without usage credits getting permanently stuck — the session now automatically compacts back under the standard context limit - Fixed a repeating "an image in the conversatio...

2.1.170

2.1.170

- Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Fable’s capabilities exceed those of any model we’ve ever made generally available. Update to version 2.1.170 for access. https://www.anthropic.com/news/claude-fable-5-mythos-5 - Fixed sessions not saving transcripts (and not appearing in --resume) when launched from the VS Code integrated terminal or any shell that inherited Claude Code environment variables.

2.1.169

- Added `--safe-mode` flag (and `CLAUDE_CODE_SAFE_MODE`) to start Claude Code with all customizations (CLAUDE.md, plugins, skills, hooks, MCP servers) disabled for troubleshooting - Added `/cd` command to move a session to a new working directory without breaking the prompt cache mid-session - Added a `disableBundledSkills` setting and `CLAUDE_CODE_DISABLE_BUNDLED_SKILLS` environment variable to hide bundled skills, workflows, and built-in slash commands from the model - Fixed Up/Down arrows jumping to command history past the wrapped rows of a long input line — they now move through each visu...

2.1.166

- Added `fallbackModel` setting to configure up to three fallback models tried in order when the primary model is overloaded or unavailable; `--fallback-model` now also applies to interactive sessions - Added glob pattern support in deny rule tool-name position (`"*"` denies all tools); allow rules reject non-MCP globs, and unknown tool names in deny rules warn at startup - Hardened cross-session messaging: messages relayed via `SendMessage` from other Claude sessions no longer carry user authority — receivers refuse relayed permission requests, and auto mode blocks them - `MAX_THINKING_TOKENS...

2.1.163

2.1.161

- `OTEL_RESOURCE_ATTRIBUTES` values are now included as labels on metric datapoints, so you can slice usage metrics by custom dimensions like team or repo - `claude agents` rows now show `done/total` before the detail when work is fanned out; peek shows the longest-running item - `/mcp` now collapses claude.ai connectors you've never signed in to behind a "Show unused connectors" row - Parallel tool calls: a failed Bash command no longer cancels other calls in the same batch — each tool returns its own result independently - Fullscreen mode: clipboard now uses `wl-copy`/`xclip`/`xsel` on Linux...

- Opus 4.8 is here!

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.
