+---
+
+### 🌟 Codename: *Image Generation, Unlocked*
+
+🖼️ **Bring ideas to life with your Open Design subscription—generate images
+directly with Seedream 5.0 Pro, GPT Image 2.0, and Nano Banana 2.0.**
+
+## 🔥 Highlights
+
+- 🎨 **Three flagship image models, included with your subscription.** Generate
+  and edit images directly with Seedream 5.0 Pro, GPT Image 2.0, and Nano
+  Banana 2.0 through Open Design Cloud. The agent can pass multiple reference
+  images and explicit aspect ratio, resolution, and quality settings when the
+  selected model publishes them. Requests are checked before generation starts,
+  progress remains visible, output paths come from the daemon, and one transient
+  post-tool interruption can recover without dropping the result. Video
+  generation also runs through the same Vela integration. (#6500)
+
+- 📤 **Export, Share, and Handoff are direct actions again.** The artifact
+  viewer no longer hides these flows behind one tabbed popover. Export leads as
+  the file-delivery action; Share focuses on links and publishing; Handoff
+  returns to its split button. HTML and React component viewers use the same
+  structure, and an off-contract editor response no longer crashes the viewer.
+  (#6654)
+
+- 🤝 **Shared projects do less wasteful work and recover better.** Team project
+  sync now excludes generated trees consistently, bounds background pulls by
+  manifest size, and retries failed publishes on a finite backoff. Transient
+  workspace-context failures can recover without reusing state from a previous
+  account, conversation forks preserve the right boundary, and MCP project
+  operations attach to the signed-in workspace. (#6558, #6564, #6595, #6604,
+  #6605, #6673)
+
+## ✨ Added
+
+- MCP clients can supply several skills when starting a run; the daemon now
+  forwards every selected skill ID. (#6429)
+- The Launch Week Vol.01 site publishes five daily drops across localized
+  campaign pages. Request-time reveal controls keep unopened content out of the
+  page source. (#6647)
+- Preview iframe failures now produce bounded diagnostic events, giving support
+  a concrete signal when an artifact cannot render. (#6671)
+
+## 🔁 Changed
+
+- Qwen Code model choices now come from the user's own Qwen configuration, with
+  the built-in models retained as fallbacks. Keys stored beside those settings
+  are not read. (#6546)
+- Long speaker notes scroll inside Presenter View instead of being clipped, and
+  deck previews recover after returning to a project or loading in a hidden
+  browser tab. (#6271, #6519)
+- "Files from this turn" counts unique files rather than counting repeated
+  writes and edits to the same file. (#6420)
+
+## 🐛 Fixed
+
+### 🧠 Runs and project state
+
+- An older retry generation can no longer close a newer generation, and stale
+  successful Design runs stop reattaching on every reload. (#6578, #6600)
+- Workspace-dependent writes retry transient authority failures with bounded
+  backoff, while account changes still invalidate old workspace context.
+  Workspace errors also retain more useful diagnostic codes. (#6604, #6666)
+- Deleting a project clears its Design Browser history and viewport cache.
+  New comment pins no longer reuse a retired pin number, and invite dialogs no
+  longer close from an expired timer. (#6354, #6517, #6580)
+- Design systems created outside a workspace can be deleted again. (#6591)
+
+### 🔌 Agents and integrations
+
+- Claude Enterprise authentication is recognized during runtime detection.
+  (#6652)
+- MCP project tools use the signed-in workspace instead of returning an empty
+  project catalog after a workspace-scoped upgrade. (#6595)
+- The daemon serves the web app fallback from the configured static root, so
+  direct navigation to application routes no longer fails. (#6614)
+
+### 🖥️ Desktop and updates
+
+- Packaged launches refresh the persisted launcher path after an update. MCP
+  clients no longer relaunch an old executable and trigger a desktop restart
+  loop. (#6621)
+- The local `od://` proxy stops retrying immediately when the machine runs out
+  of sockets or file descriptors, instead of multiplying the failed requests.
+  (#6530)
+- Windows uninstall removes only the protocol registration owned by that
+  installation, and NSIS preserves the quoted protocol command across install
+  and update paths. (#6694, #6699)
+- Diagnostic exports retain the previous daemon session log and keep JSONL
+  event tails aligned to complete records. (#6531)
+
+## ⚠️ Breaking changes
+
+None.
+
+## 🩺 Known issues
+
+None reported.
+
+## ⬆️ Upgrade note
+
+Install Open Design 0.19.0 through the normal in-app update flow or the current
+installer after the stable release is available. No additional manual steps
+are documented for this release.

+title: Open Design 0.19.0 — Image Generation, Unlocked
+description: 用 Open Design 订阅把想法变成图片：直接使用 Seedream 5.0 Pro、GPT Image 2.0 和 Nano Banana 2.0 生成图像。
+---
+
+### 🌟 Codename: *Image Generation, Unlocked*
+
+🖼️ **用 Open Design 订阅把想法变成图片：直接使用 Seedream 5.0 Pro、GPT Image 2.0
+和 Nano Banana 2.0 生成图像。**
+
+## 🔥 亮点
+
+- 🎨 **订阅内直接使用三款主力图片模型。** 通过 Open Design Cloud，可以直接使用
+  Seedream 5.0 Pro、GPT Image 2.0 和 Nano Banana 2.0 生成或编辑图片。只要所选模型
+  公开了对应能力，Agent 就能传入多张参考图，并明确指定宽高比、分辨率和质量档位。
+  任务开始前会先校验参数，生成过程中持续显示进度，输出路径由 daemon 统一管理；
+  工具调用后偶发的一次中断也能恢复，不会直接丢掉结果。视频生成也走同一套 Vela
+  集成。 (#6500)
+
+- 📤 **Export、Share 与 Handoff 不再藏在同一个菜单里。** 产物查看器恢复了三个独立
+  入口。Export 负责文件交付，Share 负责链接与发布，Handoff 回到原来的分裂按钮。
+  HTML 和 React component 查看器使用同一套结构；即使外部编辑器接口返回了不符合
+  约定的数据，也不会拖垮整个查看器。 (#6654)
+
+- 🤝 **共享项目少做无用功，失败后也能自己恢复。** 团队项目同步会统一排除生成
+  目录，根据 manifest 规模限制后台拉取，并用有限次数的退避重试恢复发布。短暂的
+  workspace context 故障可以恢复，同时不会误用上一个账号留下的状态；会话分叉能
+  守住正确边界，MCP 项目操作也会使用当前登录的 workspace。 (#6558, #6564, #6595,
+  #6604, #6605, #6673)
+
+## ✨ 新增
+
+- MCP client 启动一次 run 时可以同时传入多个 skill，daemon 会转发全部已选 skill ID。
+  (#6429)
+- Launch Week Vol.01 上线五天内容，并提供多语言活动页。尚未公开的每日内容不会写进
+  页面源码，而是在请求时按日期返回。 (#6647)
+- 预览 iframe 加载失败时会记录有边界的诊断事件，排查产物无法渲染的问题时不再只能
+  靠复述现象。 (#6671)
+
+## 🔁 变更
+
+- Qwen Code 的模型选项改为读取用户自己的 Qwen 配置；内置模型仍作为 fallback。
+  配置文件旁边保存的密钥不会被读取。 (#6546)
+- Presenter View 中的长篇演讲者备注可以滚动查看，不会被裁掉；离开项目后再回来，
+  或 deck 在后台标签页完成加载时，预览也能恢复。 (#6271, #6519)
+- “本轮生成的文件”按实际文件去重计数，不再把同一文件的多次写入和编辑重复相加。
+  (#6420)
+
+## 🐛 修复
+
+### 🧠 运行与项目状态
+
+- 旧的 retry generation 不会再结束较新的 generation；已经结束的旧 Design run 也不会
+  在每次刷新后反复重连。 (#6578, #6600)
+- 依赖 workspace 的写操作遇到短暂的 authority 故障时会有限重试；账号切换后，旧的
+  workspace context 仍会立即失效。Workspace 报错会保留更有用的诊断码。
+  (#6604, #6666)
+- 删除项目时会一并清理 Design Browser 的历史记录与 viewport 缓存。新评论不会再
+  复用已经退役的 pin 编号，邀请弹窗也不会被过期的 timer 意外关闭。
+  (#6354, #6517, #6580)
+- 没有关联 workspace 的 design system 可以正常删除。 (#6591)
+
+### 🔌 Agent 与集成
+
+- 运行时检测可以识别 Claude Enterprise 登录状态。 (#6652)
+- MCP 项目工具会使用当前登录的 workspace；升级到 workspace scope 后，不会再只看到
+  一个空的项目列表。 (#6595)
+- daemon 会从配置好的静态目录返回 Web App fallback，直接打开应用内路由不再失败。
+  (#6614)
+
+### 🖥️ 桌面端与更新
+
+- 打包客户端更新后会刷新已保存的 launcher 路径。MCP client 不会再拉起旧程序，
+  也不会因此触发桌面端重启循环。 (#6621)
+- 本机耗尽 socket 或文件描述符时，`od://` proxy 会立即停止重试，不再把一次故障放大成
+  更多失败请求。 (#6530)
+- Windows 卸载只会移除当前安装拥有的协议注册；NSIS 在安装和更新路径中都会保留带
+  引号的协议命令。 (#6694, #6699)
+- 诊断包会保留上一次 daemon 会话的日志，JSONL 事件尾部也会从完整记录处开始。
+  (#6531)
+
+## ⚠️ 破坏性变更
+
+无。
+
+## 🩺 已知问题
+
+暂无已报告问题。
+
+## ⬆️ 升级说明
+
+稳定版发布后，可通过应用内正常更新流程升级到 Open Design 0.19.0，也可以下载安装包。
