本版把图标栏移到窗口最左侧并加入反馈入口与三档显示方式，新增模型选择器搜索与分组、HTML 文件页面预览和「视觉效果」节能档，补齐终端界面的多个按键，并修复队列编辑、回退重发、反馈截图和带天空主题包长时间占用显卡的问题。
新增
- 图标栏移到窗口最左边，底部新增带未读角标的「发送反馈」入口；外观页「图标栏」改为始终显示（默认）／仅侧栏折叠时显示／从不显示，立即生效 (#12428)
- 输入框的模型选择器带搜索框（输入即过滤，回车选第一项，Esc 关闭），按服务商分组并固定显示分组标题，条目改为单行，当前模型保留勾选，声明可读图的模型带「读图」标记 (#12442)
- 工作台文件浏览器里打开
.html/.htm文件时，标签页新增「预览」视图（默认）：按网页打开，同目录的样式、脚本、图片照常加载，文件变化后自动刷新，未保存的草稿不会被覆盖 (#12443) - 设置的外观页「高级外观」新增「视觉效果」：完整（默认）／节能。节能档去掉磨砂玻璃、动态天空和颗粒，布局不变；只作用于本机，立即生效 (#12448)
- 终端界面的工具审批和计划审批卡片支持用
j/k和Ctrl+N/Ctrl+P移动光标 (#12419 by @xxoingr) - 终端界面的提问卡片支持
j/k上下移动、h/l在问题之间左右切换 (#12420 by @xxoingr) - 终端界面的
/mcp面板支持l/右方向键进入服务的工具列表，h/左方向键返回或关闭面板，q直接关闭 (#12421 by @xxoingr) - 终端界面在开启应用内鼠标捕获时，没有选中文字的右键会粘贴剪贴板里的文字，与 1.x 一致，通过 SSH 连接时仍显示原有提示；输入框隐藏时不粘贴 (#12436 by @xxoingr)
- 终端界面在回合运行中按
Ctrl+Enter，把输入框内容作为引导发送，效果与Ctrl+S相同，在下一个工具边界送达；空闲时按它不做任何事，不会把想换行的草稿提交出去 (#12437 by @xxoingr)
变更
- 打开会话窗格时，MCP、改动、上下文和队列不再在状态返回前后各读取一次；在测试夹具里这四项各由两次降为一次，实际耗时变化尚未实测 (#12344 by @KHG420)
- Go 工具链升到 1.26.9、网络库
golang.org/x/net升到 v0.60.0，清除漏洞扫描对本程序报告的 11 项可达漏洞，扫描结果为 0；只影响构建，没有源码改动 (#12446)
修复
- 带天空的主题包不再让显卡持续满载：天空画布降到每秒 15 帧，窗口不可见或失焦时停绘，面板模糊改为更实的底色。RTX 3060 上空闲占用从 9.3% 降到 1.0%，集成显卡未实测 (#12448)
- 连续点击队列里两条的「编辑」时，先点的那条较晚返回，不再覆盖后点那条的编辑框和未保存的草稿；较早的拒绝提示也不再盖掉已打开的编辑框 (#12411 by @KHG420)
- 编辑已发送的消息并重发时，如果回退失败，编辑框保留修改的文字并在原处显示错误，可直接重试，不再关闭编辑框后什么都没发出去 (#12426 by @KHG420)
- 反馈截图还在读取时提交反馈再点「再写一条」，上一条的截图不再混进下一条反馈 (#12423 by @KHG420)
- 打开反馈对话框后，焦点偶尔停在标签页上而不进入正文输入框的问题已修复 (#12439)
- 已发送消息里粘贴或上传并保存的图片现在显示预览；图片读取失败时保留预览框并显示「图片不可用」，竖图不再撑出预览框 (#12332 by @KHG420)
- 标题栏的设备面板在云端访问离线时，会区分说明是未登录、中继不可达还是中继拒绝，不再一律显示为未登录 (#12429 by @icebear02)
- 终端界面输入框里调出了多行历史条目后，上下键可以继续往更早的条目翻，不再卡在该条目的第一行 (#12435 by @xxoingr)
- 项目里声明的 MCP 服务启用后，若命令、参数、环境变量或网址被改动，会回到「待授权」并显示将要启动的命令；升级后已启用的项目服务会再询问一次 (e2d8eba, GHSA-j7r7-jh9q-wrq2)

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 从 .deb 安装。
三个平台都能自更新：Linux 走自己的包，Windows 运行下一个安装器，macOS 替换自身 bundle。
