🤖 Claude Code 更新 v2.1.86

发布日期: 2026-03-28
⚠️ 新版本发布

✨ 新增功能

  • Added X-Claude-Code-Session-Id header to API requests so proxies can aggregate requests by session without parsing the body
  • Added .jj and .sl to VCS directory exclusion lists so Grep and file autocomplete don’t descend into Jujutsu or Sapling metadata

🐛 重要修复

  • Fixed --resume failing with “tool_use ids were found without tool_result blocks” on sessions created before v2.1.85
  • Fixed Write/Edit/Read failing on files outside the project root (e.g., ~/.claude/CLAUDE.md) when conditional skills or rules are configured
  • Fixed unnecessary config disk writes on every skill invocation that could cause performance issues and config corruption on Windows
  • Fixed potential out-of-memory crash when using /feedback on very long sessions with large transcript files
  • Fixed --bare mode dropping MCP tools in interactive sessions and silently discarding messages enqueued mid-turn
  • Fixed the c shortcut copying only ~20 characters of the OAuth login URL instead of the full URL
  • Fixed masked input (e.g., OAuth code paste) leaking the start of the token when wrapping across multiple lines on narrow terminals
  • Fixed official marketplace plugin scripts failing with “Permission denied” on macOS/Linux since v2.1.83
  • Fixed statusline showing another session’s model when running multiple Claude Code instances and using /model in one of them
  • Fixed scroll not following new messages after wheel scroll or click-to-select at the bottom of a long conversation

⚡ 优化改进

  • Improved prompt cache hit rate for Bedrock, Vertex, and Foundry users by removing dynamic content from tool descriptions
  • [VSCode] Fixed extension incorrectly showing “Not responding” during long-running operations
  • [VSCode] Fixed extension defaulting Max plan users to Sonnet after the OAuth token refreshes (8 hours after login)

💡 深度点评

核心亮点

  • Token 消耗深度优化：Read 工具通过采用紧凑行号格式及重复读取去重技术，配合 @ 文件引用改用原始字符串（取消 JSON 转义），有效降低了上下文占用。
  • 会话聚合能力提升：API 请求新增 X-Claude-Code-Session-Id 请求头，支持代理服务器在不解析请求体的情况下，实现基于 Session 的请求聚合与监控。
  • 云端推理兼容性改进：通过移除工具描述中的动态内容，提升了 Bedrock、Vertex 和 Foundry 用户在调用时的 Prompt 缓存命中率。

值得注意的修复

  • 跨目录文件操作：修复了在配置特定规则时，无法编辑或读取项目根目录外文件（如 ~/.claude/CLAUDE.md）的权限限制问题。
  • 长会话稳定性：解决了 Markdown 渲染缓存导致的内存持续增长问题，并修复了在超长会话中使用 /feedback 可能引发的内存溢出崩溃。

个人评价

v2.1.86 版本是一次侧重于「工业级稳定性」和「成本控制」的迭代。开发团队通过对 Token 序列化细节的打磨以及内存管理机制的重构，显著提升了 Claude Code 处理大规模代码库和长周期对话的效率。此外，针对 Bedrock 等云端平台缓存命中率的优化，反映了该工具正在持续加强对企业级开发环境的适配能力。
