本次更新 Monet 2.2 正式版：工作台布局与切换更稳定，会话内查找和 Diff 阅读更高效，并进一步完善 Codex 与插件技能支持。 新增

• 会话内查找 — 在任意会话列中使用 Cmd/Ctrl+F 或标题栏按钮打开局部查找，显示匹配计数，并用 Enter、Shift+Enter 在结果间前后跳转。
• 发现已安装插件提供的技能 — 工坊现在会扫描本地已安装插件及其市场来源，将插件附带的技能与其他技能统一展示。 改进
• 工作台列宽保持稳定 — 新增、关闭和切换会话不再打乱既有列宽；窗口与监控栏变化只改变可见区域，并保留 Shift 联动调整能力。
• 工作台标签支持拖拽排序 — 标签可直接横向拖动重新排列，活动状态与新顺序会持久保存。
• 最近工作台标签快速恢复 — 最近访问的标签采用有界缓存，来回切换时保留滚动位置和草稿，减少重复加载闪烁，同时限制后台资源占用。
• Edit 工具升级为详细 Diff Viewer — 新增行号、增删统计、行级与词级高亮以及长上下文折叠；Claude Code 与 Codex 共用同一套中立 Diff 展示。
• 渠道模型目录可从上游刷新 — 渠道配置可以获取最新模型目录，让新增或调整后的可用模型及时进入选择器。 修复
• Codex 会话恢复与工具内容修复 — 修复 app-server 重连后的会话恢复、图片附件与工具结果显示，以及新增文件 Diff 被错误显示为零改动的问题。
• 本地文件与交付物预览修复 — 修复工作区外合法本地文件无法打开或预览的问题，并保持路径与内容类型校验。
• 工作台细节修复 — 修复列宽变化后输入框高度未及时重算，以及全景图导出未完整保留命令外壳等问题。 What's new in Monet Monet 2.2 stable brings steadier Workbench layouts and switching, faster in-session find and diff reading, and stronger Codex and plugin-skill support. New
• Find within a session — Open scoped find in any session column with Cmd/Ctrl+F or the header button, see match counts, and move backward or forward with Shift+Enter and Enter.
• Discover skills contributed by installed plugins — Workshop now scans locally installed plugins and their marketplace sources, showing bundled skills alongside other available skills. Improved
• Stable Workbench column widths — Adding, closing, and switching sessions no longer reshuffles existing widths; window and monitor-rail changes only affect the viewport, while Shift-linked resizing remains available.
• Drag to reorder Workbench tabs — Tabs can be rearranged directly by dragging; the active tab and the new order persist.
• Fast restoration of recent Workbench tabs — A bounded recent-tab cache preserves scroll position and drafts when switching back and forth, reducing reload flashes without unbounded background resource use.
• Detailed Diff Viewer for Edit tools — Adds line numbers, change statistics, line- and word-level highlighting, and folding for long unchanged regions; Claude Code and Codex share the same neutral diff surface.
• Refresh channel model catalogs from upstream — Channel settings can fetch the latest model catalogs so newly available or updated models reach the picker promptly. Fixed
• Codex session recovery and tool content — Fixed session recovery after app-server reconnects, image attachments and tool-result rendering, and new-file diffs incorrectly appearing as zero changes.
• Local files and deliverable previews — Fixed opening and previewing valid local files outside the workspace while retaining path and content-type validation.
• Workbench details — Fixed composer height not being remeasured after column resizing and panorama exports not preserving the complete command shell. Full Changelog: https://github.com/zenolab124/monet/compare/v2.1.16...v2.2.2
