2.1.21 更新了什么What's new in 2.1.21
这一版围绕「找得到、打得开、说得清」：主界面多了最近打开的文档，打开时能看见进度，打不开的情况更少了，遇到问题时还有一个会把话整理成工单的助手。
This release is about finding your documents, opening them reliably, and telling us clearly when something goes wrong — a recent-documents list, visible progress while a document opens, fewer failed opens, and an assistant that turns your description into a ticket.
- 最近打开的文档：主界面新增 Recent，与 PDF Tools 并列；双击直接打开，每行 ✕ 移除单条，Clear all 清空列表；
- 打开时有反馈：双击后该行显示转圈，文档真正起来之后再停几秒才收起；
- 打开文档更稳：只要 office 模块还活着就继续等，只有真卡死（长时间没有界面、也没有任何进展）才清理并重试一次；同一份文档连点也不会再起一堆 office；
- Feedback Assistant（反馈助手）：设置页与 Send feedback 并列；用自己的话说问题，助手帮你整理成工单，Submit 直接建单并给出工单编号；每条 AI 回复都带 Report；
- 日志与崩溃取证：日志按模块、按天分文件；反馈自动附上今天和昨天的日志，以及 Windows 事件日志里的崩溃记录。只上传诊断信息，不含文档内容。
- Recent documents — a new Recent tab next to PDF Tools; double-click a row to open it, ✕ removes one entry, Clear all empties the list;
- Visible progress — the row you double-clicked shows a spinner, which stays a few seconds after the document actually appears;
- More reliable opening — the app keeps waiting while the office module is alive and only cleans up and retries once when it is genuinely stalled; repeated clicks no longer pile up office processes;
- Feedback Assistant — sits next to Send feedback in Settings; describe the problem in your own words, the assistant turns it into a ticket, and Submit files it with an ID; every AI reply has a Report link;
- Logs and crash evidence — logs are now split per module and per day, and a report carries today's and yesterday's logs plus crash records from the Windows event log. Only diagnostics are uploaded, never document content.
1. 最近打开的文档1. Recent documents
主界面右上角有两个并列的标签：PDF Tools 和 Recent。点 Recent 就能看到最近打开过的文档，最多 12 条，最新的在最上面。
The top-right corner of the home screen now has two tabs: PDF Tools and Recent. Click Recent to see the documents you opened lately — up to 12 entries, newest first.
- 双击一条：直接打开这份文档（PDF 交给套件里的 PDF 编辑器，其余交给 office 模块）；
- 每行右侧的 ✕：只把这一条从列表里移除；
- Clear all：清空整个列表。
- Double-click a row to open that document (PDFs go to the suite's PDF editor, everything else to the office module);
- The ✕ on the right removes just that entry;
- Clear all empties the whole list.
列表里不只有从主界面打开的文档：从资源管理器双击、从右键菜单打开、在 office 里 File ▸ Open 打开的、以及用 PDF 编辑器打开的，都会出现在这里。
The list is not limited to files opened from the home screen: documents opened from Explorer, from the right-click menu, from File ▸ Open inside the office module, or in the PDF editor all show up here too.
2. 打开时有转圈2. A spinner while a document opens
双击之后，那一行的右侧会转起一个小圈，表示「正在打开」。等文档窗口真的出来，转圈还会再停 4 秒左右才收起——因为窗口画出来之后 office 还在继续读取文档内容，收得太早容易让人以为没反应。
After you double-click, a small spinner appears on that row to show the document is opening. Once the document window actually shows up the spinner stays for a few seconds before it disappears — the office module is still reading the document after its window is drawn, and hiding it too early looks like nothing is happening.
PDF 走的是同一个指示器：等 PDF 编辑器的窗口出来之后同样再停几秒。
PDFs use the same indicator: it waits for the PDF editor window and then holds for a few seconds as well.
3. 打开文档更稳3. More reliable opening
以前 office 模块启动较慢时，可能在还在启动的过程中就被判成「打开失败」；这一版改成只要 office 进程还活着就继续等，低配机器冷启动也不会被误判。
Previously a slow office start could be reported as a failure while it was still starting up. The app now keeps waiting as long as the office process is alive, so even a cold start on a slow machine is not misjudged.
- 真卡死才动手：连续两分钟没有任何界面、CPU 时间也毫无推进，才判定卡住；这时只清理这次启动带出来、从未显示过窗口的 office 进程，然后按原参数重开一次；
- 连点不会越点越糟：同一份文档在 10 秒内被反复请求，会复用同一次启动，而不是再起一个新实例；
- 失败时说清原因：真打不开会给出可读的原因（含退出码解释），并可直接 Send feedback，日志自动附上。
- Only intervene when it is really stuck — two full minutes with no window and no CPU progress counts as stuck; then the app cleans up only the office processes spawned by this launch that never showed a window, and starts them again with the same arguments;
- Repeated clicks are harmless — asking for the same document again within 10 seconds reuses the launch in flight instead of spawning another instance;
- Readable failures — if it really cannot open, you get an explanation (including what a non-zero exit code means) and a Send feedback button with the logs attached.
4. Feedback Assistant（反馈助手）4. Feedback Assistant
设置页里，Feedback Assistant 和 Send feedback 是两个并列的入口：前者用对话整理问题，后者是你自己写。遇到说不清的问题，选前者。
In Settings, Feedback Assistant sits next to Send feedback: the former helps you put the problem into words through a short conversation, the latter is the form you write yourself. If the problem is hard to describe, start with the assistant.
- 用自己的话描述：「双击 docx 之后一直转圈，Word 窗口没出来」；助手会追问关键细节（哪个功能、什么时候开始、能否复现）；
- 有报错截图的话可以点 Choose image… 附上（最多 3 张，每张 8 MB）；
- 整理好后点 Submit，助手直接建单，弹窗给出工单编号——不用再填一遍反馈表；
- 每条 AI 回复下面都有 Report，如果回复不对或不合适，点一下就能举报。
- Describe it in your own words: “double-clicking a docx just spins, no Writer window” — the assistant asks for the details that matter (which feature, when it started, whether it is reproducible);
- If you have a screenshot of the error, use Choose image… (up to 3 images, 8 MB each);
- When it reads right, press Submit: the assistant files the ticket itself and shows you the ticket ID — there is no second form to fill in;
- Every AI reply has a Report link, so you can flag a reply that is wrong or inappropriate.
5. 反馈会带上什么5. What a report carries
为了让问题能一次定位，反馈会自动附带：
So that a report can be acted on the first time, it carries:
- 今天和昨天的日志（按模块分文件：外壳与 office 启动、打印、PDF 编辑器、office 商店桥、扫描）；
- Windows 事件日志里本套件相关进程的崩溃记录（异常码 + 故障模块）；
- 应用与包版本、系统版本、界面语言、许可状态、你最近打开过的文档路径。
- Today's and yesterday's logs, split by module (shell and office launches, printing, PDF editor, office store bridge, scanning);
- Crash records for the suite's processes from the Windows event log (exception code and faulting module);
- App and package version, OS version, UI language, licence state, and the paths of the documents you opened recently.
