本版加入从任意回复分支会话、会话批量操作、模型显示别名和 MCP 工具定义变更审批，并修复长对话里拖选文字卡死、重载后丢失撤销入口等问题。
新增

- 从上下文环和检查器就能压缩上下文 (#12777)
- 对话导航旁显示当前计划 (#12803)
- 浏览器面板新增宽屏模式，打开时仍能看到对话；浏览器页面可以逐个或批量关闭 (#11762, #12806)
- 文件面板右键增加「复制路径」和「复制引用」，名称里含冒号或以反斜杠结尾而无法表示成引用时会禁用后者 (#12818, #12842 by @XTLine)
- 可以给每个模型设置显示别名；添加来源前可以批量检测模型 (#12821, #12835)
- 模型偏好里可以设置联网搜索使用的模型 (#11761)
- MCP 服务器的工具定义变更后，需要重新批准才会启用 (#12829)

- 可以在右键菜单里引用选中的回复文字 (#12836)
- 发送快捷键成为统一的偏好设置 (#12837)
- 反馈表单里可以直接打开日志文件夹；反馈对话折叠显示并保留未读状态 (#12768, #12802)
- 正在使用的版本被撤回时，应用会告知用户 (#12769)
- 工作台「+」按钮会显示启动器，从导航打开聚焦会话的文件 (#12826 by @XTLine, #12832)
变更
- 会话标签页改为按需开启 (#12841)
- 项目里置顶的会话排在最前并带标记 (#12845)

- 对话壁纸下的文字光晕可以配置 (#12839)
- 当前使用的模型在输入框的选择器里排第一 (#12801)
- 手机窄屏上未输入时的输入框更紧凑，并保留分支标识 (#12800, #12813)
- 左侧图标栏的图标与对应设置分区一致；设置页打开时侧边栏开关仍可用 (#12753, #12798)

- 多个会话共用一个工作区时，写入改用乐观租约 (#12772)
- 没有声明检查的项目里，写过文件的未识别命令不再免除验证 (#12848 by @boscocp)
修复
- 长对话里拖选文字会卡死：选区经过的远处块改为按对话原文保留，1200 轮对话里跨屏选择从数十秒降到约 0.1 秒；这些中间块复制出的是对话原文，不再带界面标签 (#12850)
- 一个超过 128 个字符的 MCP 工具名会让整个会话的每次请求失败：现在只缩短工具名部分 (#12849)

- 终端界面里补全菜单中按 Esc 会同时停止正在运行的回合 (#12761 by @xxoingr)
- 记忆改名时先下线旧名再发布；归档记忆恢复失败后可以重试，索引与归档保持一致 (#12785 by @chuiwenwei, #12816 by @chuiwenwei, #12819 by @chuiwenwei)
- 自动召回的记忆在轨迹里记录是被条数还是字符预算截掉的 (#12843 by @thehui13)

Full Changelog: studio-v2.37.0...studio-v2.38.0
macOS 已用 Developer ID 签名并公证，打开时不需要清除隔离属性。Windows 的窗口、内核与安装器都经 Certum 代码签名证书做了 Authenticode 签名。Linux Debian 系从 .deb 安装，Fedora、RHEL、openSUSE 等从 .rpm 安装（sudo dnf install ./ReasonixStudio-linux-amd64.rpm）。
三个平台都能自更新：Linux 的 .deb 走自己的包（.rpm 的自更新尚未提供，请手动下载新包），Windows 运行下一个安装器，macOS 替换自身 bundle。
