🤖 Claude Code 更新 v2.1.78

发布日期: 2026-03-18
⚠️ 新版本发布

✨ 新增功能

  • Added StopFailure hook event that fires when the turn ends due to an API error (rate limit, auth failure, etc.)
  • Added ${CLAUDE_PLUGIN_DATA} variable for plugin persistent state that survives plugin updates; /plugin uninstall prompts before deleting it
  • Added effort, maxTurns, and disallowedTools frontmatter support for plugin-shipped agents
  • Added ANTHROPIC_CUSTOM_MODEL_OPTION env var to add a custom entry to the /model picker, with optional _NAME and _DESCRIPTION suffixed vars for display

🐛 重要修复

  • Fixed git log HEAD failing with “ambiguous argument” inside sandboxed Bash on Linux, and stub files polluting git status in the working directory
  • Fixed cc log and --resume silently truncating conversation history on large sessions (>5 MB) that used subagents
  • Fixed infinite loop when API errors triggered stop hooks that re-fed blocking errors to the model
  • Fixed deny: ["mcp__servername"] permission rules not removing MCP server tools before sending to the model, allowing it to see and attempt blocked tools
  • Fixed sandbox.filesystem.allowWrite not working with absolute paths (previously required // prefix)
  • Fixed /sandbox Dependencies tab showing Linux prerequisites on macOS instead of macOS-specific info
  • Fixed .git, .claude, and other protected directories being writable without a prompt in bypassPermissions mode
  • Fixed ctrl+u in normal mode scrolling instead of readline kill-line (ctrl+u/ctrl+d half-page scroll moved to transcript mode only)
  • Fixed voice mode modifier-combo push-to-talk keybindings (e.g. ctrl+k) requiring a hold instead of activating immediately
  • Fixed voice mode not working on WSL2 with WSLg (Windows 11); WSL1/Win10 users now get a clear error

⚡ 优化改进

  • Improved memory usage and startup time when resuming large sessions
  • [VSCode] Fixed a brief flash of the login screen when opening the sidebar while already authenticated
  • [VSCode] Fixed “API Error: Rate limit reached” when selecting Opus — model dropdown no longer offers 1M context variant to subscribers whose plan tier is unknown

💡 深度点评

核心亮点

  • 插件持久化状态与配置增强：新增 ${CLAUDE_PLUGIN_DATA} 变量支持跨版本的插件状态存储，并为插件 Agent 引入了 effort、maxTurns 和 disallowedTools 的 frontmatter 支持，显著提升了复杂自动化任务的可控性。
  • 灵活的自定义模型接入：通过 ANTHROPIC_CUSTOM_MODEL_OPTION 环境变量，用户可以在 /model 选择器中添加自定义模型条目，便于适配特定的模型版本或实验性端点。
  • 大型会话交互体验优化：改进了超大型会话（>5 MB）恢复时的内存占用与启动速度，配合响应文本的逐行流式输出，有效降低了长任务执行时的感知延迟。

值得注意的修复

  • 权限校验与安全增强：修复了 deny 规则下 MCP 工具过滤不彻底的问题，并解决了 Sandbox 在依赖缺失时静默关闭的风险，现在系统会提供明确的启动警告。
  • 开发环境路径兼容性：修复了从 macOS Dock 或 Spotlight 启动 VS Code 时，Bash 工具无法正确识别 Homebrew 等 PATH 环境变量下二进制文件的问题。

个人评价

v2.1.78 版本是一个典型的以「健壮性」和「开发者体验」为核心的迭代。通过引入插件持久化变量和更细粒度的 Agent 配置，Claude Code 正在为更复杂的端到端工作流铺路。此外，针对超大会话历史截断和内存溢出的修复，解决了重度用户在处理大型代码库时的核心痛点。整体而言，这一版本在不改变核心交互逻辑的前提下，大幅强化了工具在企业级开发环境和复杂插件生态中的适用性。
