版本v2.1.122更新摘要
阅读原文· github.com本次更新主要新增了通过环境变量选择Bedrock服务层级的功能，并支持在/resume搜索框粘贴PR链接以定位创建该PR的原始会话。同时修复了多项关键问题：修正了源会话含时间线回退条目时，/branch命令可能创建失败分支的问题；解决了发送给新版模型的图像被错误调整为2576px（应为2000px上限）的问题；增强了OpenTelemetry日志记录，确保数字属性以数值类型输出；并修复了Vertex AI/Bedrock在生成会话标题等场景下可能返回无效请求错误的问题。此外，还包含对MCP工具显示、CLI命令退出行为等多项细节的优化与修正。
What's changed
Added ANTHROPIC_BEDROCK_SERVICE_TIER environment variable to select a Bedrock service tier (default, flex, or priority), sent as the X-Amzn-Bedrock-Service-Tier header
Pasting a PR URL into the /resume search box now finds the session that created that PR (GitHub, GitHub Enterprise, GitLab, and Bitbucket)
/mcp now shows claude.ai connectors hidden by a manually-added server with the same URL, with a hint to remove the duplicate
Clarified the /mcp message shown when an MCP server is still unauthorized after the browser sign-in flow
