v0.5.10

Improvements

• Reduce Assistant context-limit failures by trimming older sent conversation turns and bounding reference lists. Keep the full local history and the current request.
• Retry or resume the selected task with its original question, folder and images, including when conversation history is disabled. Restore running-task status after refresh or a temporary connection loss.
• Report task-record saving failures, retain unsaved results during the current app run and offer saving again. Show the actual connection or service error when automatic continuation fails.
• Remove the redundant summary buttons and persistent waiting-budget prompt. Show one main recovery action per unresolved error, with parameter settings when relevant; hide superseded retry actions.
• Validate model parameters before saving. New configurations use the model's default reasoning, while existing explicit settings remain compatible.
• Use Alt-hover for file previews alongside Ctrl-click selection. Move and resize the preview window, remember its layout, and read long file names from tooltips without expanding file rows.

修复与完善

• 通过精简发送的旧对话和限制资料编号清单，减少助手会话超限；保留本机完整记录和本轮要求。
• 重试和续接绑定被选中的原任务，恢复原问题、目录和图片，关闭聊天历史后也能带回原图；刷新或连接短暂中断后继续核对运行状态。
• 任务记录保存失败时明确提示，本次运行内保留尚未保存的结果并支持重新保存；自动补写失败显示真实连接或服务错误。
• 移除重复的“仅整理已有资料/结果”和常驻“调整等待”入口。未解决的错误只提供一个主要恢复操作，参数相关错误再提供设置入口；旧操作被后续恢复承接后不再重复显示。
• 保存前检查模型参数的范围和等待预算关系。新配置使用模型默认思考程度，已有显式设置保持兼容。
• 文件预览改为 Alt 悬停，与 Ctrl 单击多选配合使用；预览窗口可移动、缩放并记住布局，长文件名单行显示并提供完整名称提示。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. Existing settings and OCR components remain compatible; file access still requires authorization and per-file confirmation.
• If results cannot be saved, keep the app running until storage is available and the results have been saved again. In-memory recovery does not survive app exit.
• 需要 Windows x64 和 Microsoft Edge WebView2。继续兼容已有设置和 OCR 组件，文件访问仍需授权及逐文件确认。
• 结果无法保存时，请保持应用运行，处理存储问题后重新保存；仅保留在内存中的结果无法保证退出后恢复。
• Application build / 应用构建版本 2026.1111.1932。

Verification scope / 验证范围

• 21 targeted Rust checks, Assistant/settings state checks, local frontend production and Windows installer builds passed. The embedded version, x64 runtime, bundled components and SHA-256 were verified. Real model requests, desktop end-to-end flows and installation/upgrade were not tested for this release; no GitHub Actions workflows are configured.

v0.5.9

Improvements

• Find tools, files and folders by name or path in the quick panel, and reopen recent items. Text and Excel translation are available in the Assistant.
• See more files at once in the compact File Workspace. Ctrl-click files on the current page and use Send to OCR to add supported documents and images to the queue together.
• Customize page, search and quick panel shortcuts in Settings, including the global quick panel shortcut. Press Ctrl+Enter on a focused file or use the preview pin to keep it open.
• Preview worksheets in legacy Excel files (.xls) and move between slides to read text in PowerPoint files (.ppt, .pptx).

修复与完善

• 快捷面板可按名称或路径查找工具、文件和文件夹，并打开最近访问的项目。文本和 Excel 翻译可在助手中使用。
• 文件工作区采用更紧凑的布局，首屏可显示更多文件。在当前页按住 Ctrl 单击可增减选中项，点击「送入 OCR」即可批量加入待识别清单。
• 在「设置 → 快捷键」中可自定义页面切换、搜索、快捷面板及全局唤起键。聚焦文件后按 Ctrl+Enter，或使用预览中的图钉，可固定预览。
• 支持预览旧版 Excel（.xls）的工作表，以及逐页查看 PowerPoint（.ppt、.pptx）中的幻灯片文字。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. PowerPoint previews show slide text. Legacy Excel previews show cell values and cached formula results. The OCR queue accepts PDF, PNG, JPEG, BMP and TIFF.
• 需要 Windows x64 和 Microsoft Edge WebView2。PowerPoint 预览显示幻灯片文字，旧版 Excel 预览显示单元格值及已有的公式结果。OCR 支持 PDF、PNG、JPEG、BMP 和 TIFF。
• Application build / 应用构建版本 2026.1110.1651。

Verification scope / 验证范围

v0.5.8

Improvements

• Right-click a file to open its containing folder and select it in Windows Explorer. Right-click a directory to open it directly; selected files also have an explicit folder button.
• Distinguish 18 file categories with a consistent SVG icon set in the file list and quick panel: red PDF, blue Word, green Excel, orange PowerPoint and white text icons, plus images, archives, audio, video, code, configuration, CAD, email, databases, applications and fonts.
• Recognize legacy Office formats and uppercase extensions, retain a generic icon for unknown formats, and suppress the browser context menu in the file panel.

修复与完善

• 右键文件即可在资源管理器中打开所在文件夹并选中文件，右键目录直接打开该目录；所选文件另提供“打开所在文件夹”按钮。
• 文件列表和快捷面板统一使用 18 类 SVG 图标：PDF 红色、Word 蓝色、Excel 绿色、PowerPoint 橙色、文本白色，并覆盖 OFD、图片、压缩包、音视频、代码、配置、CAD、邮件、数据库、应用和字体等常见格式。

Verification scope / 验证范围

• Local frontend and Windows installer builds, 18 static SVG resources, production-bundle checks, directory-action checks and SHA-256 verification passed. A candidate with the same application behavior was upgraded and opened locally; this release increments its build version. A complete desktop workflow was not run, and no GitHub Actions workflows are configured.
• 本机前端与 Windows 安装包构建、18 枚静态 SVG 资源、生产构建内容、目录操作检查及 SHA-256 核验通过。功能一致的候选版已在本机覆盖安装并成功启动，本次发布递增构建版本；未进行完整桌面流程验收，仓库未配置 GitHub Actions 工作流。

v0.5.7

Improvements

• Speed up configured OCR regions while keeping the original image resolution for text recognition. Missing or uncertain fields fall back to the original detection path; the model and inference thread count are unchanged.
• Reuse compatible first-page results. When only one eligible profile exists and a separate classification pass is needed, try the upper part of the first page first, then fall back to the full page on a miss. Multiple profiles retain full-page conflict checks.
• Update changed OCR results incrementally and show measured rendering, detection, direction, recognition, extraction and saving times, together with OCR process CPU time.

修复与完善

• 加速已绑定字段的画框识别，文字识别仍使用原清晰度裁片；字段缺失或需要复核时自动回退原检测流程，保持原模型和推理线程数。
• 复用条件一致的首页识别结果。只有一个候选配置且需要额外分类时，先探测首页上部，未命中再识别完整首页；多个配置仍保留全页冲突判断。
• 识别进度改为增量更新，减少整批结果的复制与传输；结果详情增加页面处理、文字检测、方向判断、文字识别、字段提取、保存及 OCR 进程 CPU 的实测耗时。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. OCR remains local. Existing profiles, page/region boundaries, file-state checks, non-replacing renames and undo remain supported. Performance depends on document quality and configuration; fallback cases may take longer.
• 需要 Windows x64 和 Microsoft Edge WebView2。OCR 仍在本机处理，继续兼容已有配置，保留页范围、画框、文件状态校验、不覆盖改名和撤销保护。速度取决于文档质量及配置，触发回退时可能耗时更长。
• Application build / 应用构建版本：2026.1102.37。

Verification scope / 验证范围

• Using an unchanged saved quotation profile and 10 independently authored fictional scans, three native desktop rounds achieved median times of 11.02 → 5.30 seconds for direct recognition (2.08×), and 27.03 → 12.24 seconds for automatic matching, export and rename (2.21×). All 30 fields and 10 filenames matched the ground truth in every round. These measurements apply to this local fixture set, not every document.
• 使用未修改的已有报价单配置及独立生成的 10 份虚构扫描文件，三轮原生桌面测试中，直接识别的中位耗时由 11.02 秒降至 5.30 秒（2.08 倍速度）；自动匹配、导出并改名由 27.03 秒降至 12.24 秒（2.21 倍速度）。每轮 30 个字段及 10 个文件名均符合独立真值；结果仅代表本机这组样本，不保证所有文档均可翻倍。
• Local regression checks cover precise fallback, missing header keywords, profile conflicts, cancellation/retry, export, rename/undo and original-file hashes. Worker measurements showed lower cumulative CPU time and peak memory. No original business documents or paid services were used. Fresh-install acceptance and cloud CI were not run; the repository has no configured GitHub Actions workflows.
• 本机回归覆盖精确检测回退、标题区未命中、多配置冲突、取消重试、导出、改名撤销及原文件哈希；OCR 子进程的累计 CPU 时间与峰值内存均下降。未使用真实业务文档或付费服务，未进行全新安装验收或云端 CI；仓库未配置 GitHub Actions 工作流。

v0.5.6

Improvements

• Export one or all OCR profiles, including field rules and selected regions, as JSON for later import. Existing files are not overwritten; oversized collections must be exported separately.
• Organize the OCR profile editor into fields, regions and general settings, with a clearer sample preview and region list.
• Group model connections, reply preferences and advanced settings, and clarify assistant workspace permissions and individual file approvals.

修复与完善

• 支持将单个或全部 OCR 配置导出为 JSON，保留字段规则与框选区域，便于再次导入；不会覆盖已有文件，合辑过大时需分别导出。
• OCR 配置编辑器按字段、框选区域和通用设置分区，调整样本预览及区域列表，方便查看和修改。
• 模型设置按连接、回复偏好和高级参数分组，优化助理工作目录授权与逐文件确认界面。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. OCR models run locally; optional connected services and diagnostic sharing may incur provider fees. Review redacted previews before sharing. File-state checks, non-replacing renames and undo protections remain in place.
• 需要 Windows x64 和 Microsoft Edge WebView2；OCR 模型在本机运行，可选联网服务及诊断共享可能产生服务商费用。共享前请核对脱敏预览；继续保留文件状态校验、不覆盖改名与撤销保护。
• Application build / 应用构建版本：2026.1030.2107。

Verification scope / 验证范围

• 前端生产构建、Rust 静态检查和安装配置检查通过。未进行模拟测试、完整桌面走查、全新安装验收、真实 OCR 或付费服务验证，未读取用户业务文件；仓库未配置 GitHub Actions 工作流。

v0.5.5

Improvements

• Edit saved model configurations, including their name, endpoint and model ID. Changes and replacement keys are saved only after a successful connection test; failed tests retain the original configuration. Changing the service origin requires a new key.
• Share a selected OCR result with the assistant after reviewing and editing a local redacted preview. Diagnostic sessions use the confirmed snapshot and model connection, block public search and unrelated file access, and require separate confirmation before saving configuration proposals.
• Improve document-date selection when quotation, expiry and print dates are adjacent. Score multi-value product candidates in batches before applying the configured result limit, and distinguish attempted local extraction from skipped fallback and incomplete historical records.
• Preserve known token usage and cache data when some requests omit usage. Hide textual tool-call protocols from replies and report unexecuted requests accurately.

修复与完善

• 已保存的模型配置支持编辑名称、服务地址和模型 ID；修改及新密钥测试成功后才保存，测试失败保留原配置。更换服务来源时需填写新服务密钥。
• OCR 单份结果支持“让助理诊断”：先在本机核对、删改脱敏预览，再确认共享。诊断会话只使用已确认快照和模型连接，禁止公开搜索及无关文件访问；配置方案仍需单独确认后保存。
• 完善报价日期、有效期和打印日期相邻时的字段判断；多值产品候选先分批评分再按配置数量保留，明确区分本地提取已尝试、无需回退和旧记录缺失。
• 部分请求缺少用量时保留已知 token 和缓存统计；屏蔽回复中的工具协议标签，准确提示尚未执行的请求。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. OCR models run locally; optional connected services and diagnostic sharing may incur provider fees. Automatic redaction is limited: review the preview before sharing. Existing file-state checks, non-replacing renames and undo protections remain in place.
• 需要 Windows x64 和 Microsoft Edge WebView2；OCR 模型在本机运行，可选联网服务及诊断共享可能产生服务商费用。自动脱敏有局限，共享前请核对预览；继续保留文件状态校验、不覆盖改名与撤销保护。
• Application build / 应用构建版本：2026.1029.1323（最小递增）。

Verification scope / 验证范围

• Local checks cover model-configuration updates, OCR extraction and diagnostic scope, assistant reply protocols, usage statistics and installer configuration. The release installer is production-built with matching versions and SHA-256 checksums. No full desktop walkthrough, fresh-install acceptance, real OCR or paid-service validation was performed. No user business files were read. No GitHub Actions workflows are configured.
• 本机检查覆盖模型配置修改、OCR 提取与诊断范围、助理回复协议、用量统计及安装配置；发布安装包完成生产构建、版本与 SHA-256 核验。未进行完整桌面走查、全新安装验收、真实 OCR 或付费服务验证，未读取用户业务文件；仓库未配置 GitHub Actions 工作流。

v0.5.4

v0.5.4 - 2026-10-29

Improvements

• Restore right-click-to-open on folder rows and suppress the browser context menu in blank folder panels. Keep immediate folder filtering and one-click filter clearing.
• Rename a file or folder by editing its name and confirming once, including Enter. Checks run automatically and the dialog closes after success; guarded undo remains available in rename history.
• OCR filenames automatically replace slashes and other invalid characters with underscores without requiring review for that normalization. Preserve extracted values and exports, handle Windows reserved names, and retain review for uncertain recognition or truncated names.
• Simplify the OCR toolbar, move advanced options into recognition settings, and show task history on demand. Completed list items can be hidden and restored; incomplete and uncertain results are retained.
• Improve OCR profile matching diagnostics and assistant profile proposals. Normalize supported date-format aliases, accept omitted optional values, and preserve strict validation and explicit save confirmation.
• Put stable conversation history before changing task metadata in assistant requests to improve cache reuse opportunities. Actual cache hits remain provider-reported.

修复与完善

• 恢复目录行右键直接打开文件夹，屏蔽目录面板空白处的浏览器菜单；保留目录即时筛选与一键清空。
• 单个文件或文件夹改名简化为“修改名称 → 按 Enter 或确认一次”，自动预检并在成功后关闭；可在改名记录中安全撤销。
• OCR 拟命名中的斜杠等非法字符自动替换为下划线，不再仅因此要求复核；保留识别原值和导出内容，补齐 Windows 保留名称处理，识别不确定或名称截断仍需核对。
• 精简 OCR 工具栏，高级选项收进“识别设置”，任务记录按需查看；已完成清单项支持清除与恢复，待复核、失败、中断和未完成后续步骤的结果保留。
• 完善 OCR 自动匹配诊断和助理配置方案，统一受支持的日期格式写法，兼容可选参数省略；继续严格校验必填项和未知字段，保存配置仍需用户确认。
• 助理请求将稳定历史放在每轮变化的任务资料前面，增加缓存复用机会；实际命中情况以模型服务回包为准。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. OCR models are bundled and run locally; optional connected services may charge provider fees. Renames retain file-state checks, collision numbering, non-replacing writes and undo protections.
• 需要 Windows x64 和 Microsoft Edge WebView2；OCR 模型随安装包提供并在本机处理，可选联网服务可能产生服务商费用。改名继续核对文件状态、同名自动加序号、不覆盖文件，并保留撤销保护。
• Application build / 应用构建版本：2026.1029.1322。

Verification scope / 验证范围

• Local targeted checks cover directory actions, OCR naming and completion rules, assistant request ordering, and OCR profile proposals. The release installer is production-built with matching versions and SHA-256 checksums. No complete desktop walkthrough, fresh-install acceptance, real OCR run or paid-service cache measurement was performed. No user business files were read. No GitHub Actions workflows are configured.
• 本机定向检查覆盖目录操作、OCR 命名与完成条件、助理请求顺序和 OCR 配置方案；发布安装包完成生产构建、版本与 SHA-256 核验。未进行完整桌面走查、全新安装验收、真实 OCR 或付费服务缓存命中率测量，未读取用户业务文件；仓库未配置 GitHub Actions 工作流。

v0.5.3

v0.5.3 - 2026-10-27

Improvements

• The OCR action is now explicitly “Recognize and rename in one click.” It runs recognition and automatic renaming continuously, without another rename button or filename confirmation for eligible files. Old review-only or preview-only preferences no longer interrupt new one-click tasks; the OCR-only action remains available.
• One-click tasks report completion only when every file has a successful rename record. Uncertain results, errors, locked files, and conflicts remain visible for review. Identity checks, non-replacing renames, execution records, and undo protections are retained.

修复与完善

• OCR 的一键入口明确为“一键识别并改名”，按当前配置连续完成识别与自动重命名，正常项无需再次点击改名或确认名称；兼容旧的只核对/只预览设置，保留“仅识别”分步入口。
• 只有本批全部文件都有成功改名记录时，才显示“识别与重命名已完成”。需复核、失败、占用或冲突项集中保留，继续沿用文件身份校验、不覆盖、执行记录与撤销保护。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. OCR models are bundled and run locally; optional connected services may charge provider fees. Clicking the clearly labelled one-click action authorizes that task's recognition and renaming using the current profiles; uncertain items are not forced through.
• 需要 Windows x64 和 Microsoft Edge WebView2；OCR 模型随安装包提供并在本机处理，可选联网服务可能产生服务商费用。点击明确标注的一键入口即按当前配置执行本次识别与改名；不确定或异常项不会被强行处理。
• Application build / 应用构建版本：2026.1027.1553（最小递增）。

Verification scope / 验证范围

• Reused passing checks from this session: 12 legacy-option/export-format combinations, the rename-completion regression, the existing task-authorization regression, and the frontend build. The final version is production-built and its installer configuration, versions, and SHA-256 checksums are verified. No complete GUI walkthrough, fresh-install acceptance, real OCR, or connected-service validation was performed; no user business files were read. No GitHub Actions workflows are configured.
• 复用本会话已通过的 12 种旧选项/导出格式组合、改名完成条件回归、原有任务级授权回归与前端构建；最终版本完成生产构建、安装配置、版本与 SHA-256 核验。未进行完整界面走查、全新安装验收、真实 OCR 或联网服务验证，未读取用户业务文件；仓库未配置 GitHub Actions 工作流。

v0.5.2

v0.5.2 - 2026-10-27

Improvements

• Rename a single file or folder from its context menu, selected-item action, or F2. Extensions are preserved by default; review the original and target paths before confirming.
• Renaming uses a pinned Windows source handle without replacing existing targets. Persistent intent/result records support guarded undo and interrupted-operation checks; affected paths, navigation, and indexes are refreshed, and stale OCR results require reimport.
• Ctrl+K history now records files and folders only after a successful system-open request. Selection, browsing, locating, and previews no longer add entries. Frequently used program history is retained; older mixed file/folder history starts accumulating again from explicit opens.

修复与完善

• 文件工作区新增单个文件/文件夹安全重命名：右键菜单、所选项按钮及 F2，默认保留扩展名，核对原路径和目标路径后再确认。
• 通过 Windows 源对象句柄执行不覆盖目标的改名，操作前后保留本地记录，支持安全撤销和中断状态核对。同步索引、目录后代路径、导航与最近打开记录；受影响的旧 OCR 结果需重新导入，OCR 运行期间禁止改名。
• Ctrl+K 只记录成功发起系统打开的文件/文件夹，选择、浏览、定位和预览不计入。常用程序历史继续保留；旧文件历史未区分操作来源，从实际打开重新累计。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. OCR models are bundled and run locally. The app and installer remain in Simplified Chinese; optional connected services may charge provider fees.
• Rename checks use file IDs, sizes, and Windows timestamps without reading document bodies. Only local working folders are supported. Case-only changes, links, protected objects, target paths over 240 UTF-16 units (including descendants), folders exceeding 10,000 descendants, and file systems without reliable change timestamps are rejected. Undo stops on changes or conflicts; uncertain interrupted operations require manual review. Other programs are not transactionally frozen during folder renames.
• 需要 Windows x64 和 Microsoft Edge WebView2；OCR 模型随安装包提供并在本机处理。软件界面和安装器仍为简体中文，可选联网服务可能产生服务商费用。
• 重命名仅核对文件标识、大小和 Windows 时间，不读取正文。仅支持本地工作目录；暂不支持只改大小写、链接、受保护对象、完整目标路径（含子项）超过 240 个 UTF-16 字符、目录超过 10,000 个子项或缺少可靠变更时间的文件系统。撤销遇到状态变化或名称占用会停止，无法确认的中断记录需人工处理；目录改名不能事务性冻结其他程序。
• Application build / 应用构建版本：2026.1027.1552。

Verification scope / 验证范围

• Reused passing checks from this session: 15 workspace/OCR rename safety cases, one index regression, path checks, and Rust static checks. The final version is production-built and its installer configuration, versions, and SHA-256 checksum are verified. No complete GUI walkthrough, fresh-install acceptance, real OCR, or connected-service validation was performed; no user business documents were read. No GitHub Actions workflows are configured.
• 复用本会话已通过的 15 项改名/OCR 安全用例、1 项索引回归、路径检查和 Rust 静态检查；最终版本完成生产构建、安装配置、版本及 SHA-256 核验。未进行完整界面走查、全新安装验收、真实 OCR 或联网服务验证，未读取用户业务正文；仓库未配置 GitHub Actions 工作流。

v0.5.1

v0.5.1 - 2026-10-24

Improvements

• Directory filters prioritize exact directory-name or relative-path matches before partial matches, with ranking applied before pagination.
• Clearing file-search keywords returns focus to the search box while retaining other filters.
• The default README is now in English, with a complete Simplified Chinese edition, language switching, clearer Windows download instructions, and existing screenshots and demos.

修复与完善

• 目录筛选优先展示目录名或相对路径精确匹配的结果，在候选分页前完成排序，避免目标被大量模糊结果挤到后页。
• 清空文件搜索关键词后，焦点返回搜索框，方便继续输入；其他筛选条件保留。
• 默认 README 改为英文首页，提供完整中文版和语言切换，突出 Windows 下载与快速上手，并保留已有真实截图和演示。

Compatibility / 使用说明

• Windows x64 and Microsoft Edge WebView2 are required. OCR models are bundled and run locally. The app and installer remain in Simplified Chinese; optional connected services may charge provider fees.
