• 开启后隐藏历史入口：设置侧栏的「截图历史」、托盘菜单的历史项、「打开历史」快捷键同步失效

优化与改进

Release Notes

New features

Fun arrow

• New "Fun arrow" style in the arrow property bar: hand-drawn look with a small loop at the start, slightly randomized per arrow

Screenshot history filters

• History page now has All / Screenshots / Recordings navigation plus a Filter button on the right
• Combine Today / Last 7 days / Last 30 days / Pick a range (calendar with start and end dates) with custom tags
• The old year-month dropdown is merged into the filter popover; the retention dropdown moved to Settings > Features > File output

Custom tags

• Click the source badge on a history card to edit tags (space-separated); tags are stored with the file
• Filter by any tag listed for the current navigation, combined with the time range and filename search

Remember tool style

• New option at Settings > Appearance > Other (above "Default annotation width")
• Remembers the last annotation tool style (for example the big arrow) and reuses it the next time that tool is selected; stroke width is not remembered; off by default

Custom plugin directory

• New folder button at the bottom-left of Settings > Plugins (components) to choose a custom component directory
• Existing downloaded components are migrated; subdirectories of the current directory are rejected; unavailable while downloading

Disable capture history

• New switch at Settings > Features > File output
• Hides history entry points: the sidebar item, the tray menu entry, and the Open History shortcut

Improvements

Screenshot history

• Save format: entries link to the real saved files and support PNG / JPEG / WebP / BMP; directory scanning recognizes more formats (including WebP, AVIF, JXL) and scans the recording output directory; auto-saved files are classified by filename prefix
• Deletion: files are moved to the recycle bin together with cached thumbnails; files without an index entry can also be deleted; clearing respects the current navigation

Scrolling capture

• Start / pause / resume merged into one button and one shortcut (Space, configurable in System keys); the icon follows the state
• Copy and save behave like normal captures: respect the save format and "copy as file", and register into history

Other

• System style and comment wording refinements

Bug fixes

Hotkey recording

• Recording now uses a low-level keyboard hook, so shortcuts already owned by the system or other apps can be captured
• Left/right Ctrl, Shift and Alt are normalized; recording exits cleanly on finish or cancel

WebP support

• Uses the bundled libwebp encoder instead of the system WIC WebP codec
• WebP captures and scrolling captures now save on systems without a WebP extension; animated and GIF output follow the same path

Other

• Version bumped to 0.1.8.0
• Windows 10 / 11 (x64), single-file portable

Release Notes

New features

Demo canvas: whiteboard

• Solid colors with opacity, presets (white, black, dark green, red, green, blue, custom picker), and one-click clear
• Image backgrounds (multi-select, PgUp/PgDn to page) and direct PPT slideshow (.ppt/.pptx/.pps/.dps, paging inside the canvas, slideshow ends when demo exits)
• Background can be dragged and resized from edges or corners; with "Adjust background" on, annotations go to the background layer and can be kept or cleared separately

Demo canvas: screen recording

• New "Screen recording" entry before "Reset canvas", opening a dedicated recording bar
• Start/pause, timer, system audio, microphone, and animation (GIF/WebP/APNG) recording
• "Done": stop → copy the file to the clipboard → exit demo

• "Cancel": stop and discard → stay in demo, closing the bar and clearing the selected state
• Toolbars are excluded from capture; annotations, whiteboard and key hints are recorded normally
• When idle, clicking the button opens the bar and clicking again closes it; while recording the button stays selected and the bar can be collapsed independently

Capture

• HDR display support: desktop duplication with HDR→SDR tone mapping, avoiding black or overexposed captures

OCR

• New "Compare" button on the OCR result: shows the original image, draggable, placed left → right → top
• New result presentation modes: in-place overlay / reflowed text (editable, Enter for new line, fills the selection)
• Text selection background unified to #1890FF

Quick translate

• Provider fallback order: Microsoft → Youdao → Baidu → Google → offline
• History sidebar with expand/collapse animation; clicking outside collapses it

Annotations

• Arrows/lines can connect to rectangles and ellipses: snapping to shapes on drag, with a "drag to connect" hint on hover
• Hovering the middle of a connection shows a cut marker that deletes the whole line

System keys

• Default start/pause recording shortcut changed to F2
• Recording commands now work in the demo canvas; recording and demo groups detect key conflicts with each other
• System keys group "Fullscreen canvas" renamed to "Demo"

Improvements

• "Record key presses" shows modifier prefixes immediately (e.g. Ctrl +), keeping the latest 3 entries

• Secondary toolbar now stays on the same monitor as the main toolbar
• Ctrl+C before selecting copies the color, shows a success hint, then exits capture automatically

SnowAir Lite v0.1.6

更新说明

本次更新

离线识别（升级到 PP-OCRv6）

• 离线文字识别升级到 PP-OCRv6：整图识别耗时下降至 40 毫秒级，比上一版明显更快
• 识别引擎内存大幅下降：旧方案每次识别会常驻数百 MB，新引擎常驻更小、用完即还，截图会话结束立即释放
• 空载占用优化：启动后与每次会话收工都会主动归还图形设备与空闲内存页 —— 什么都不操作时常驻从 20 多 MB 降到 5MB 以下
• 修复：截图会话收工后，识别结果面板未及时销毁

截图与保存

• 「手动保存」（含点选窗口元素）统一按「手动保存文件名格式」命名，保存对话框固定从桌面开始
• 修复：「截取全屏」的文件名不跟随格式设置的问题（现与「手动保存文件名格式」一致）
• 修复：历史里「点选窗口元素」被错标成「焦点窗口」—— 现在只有全局热键「截取焦点窗口」才标该项

截图历史

• 新增「屏幕录制」条目：视频不复制，只记录路径与一张封面，控件为 复制 / 打开所在文件夹 / 删除
• 长截图单独标记为「长截图」；「截取焦点窗口」文案改为「焦点窗口」

其他

• 「离线文字识别」插件说明更新：PP-OCR 最新一代通用文字识别，支持简体中文、繁体中文、英文、日文及 46 种拉丁语系语言，共 50 种语言

上一版（0.1.6）内容

• 录屏：临时全局键（开始 / 暂停录制、鼠标穿透、隐藏 / 显示工具栏等）在进入录屏阶段即可使用，焦点在被录程序上同样生效
• 录屏：开始录制后锁定选框尺寸（四周控件隐藏），但可整体平移；录制内容随选框移动，跨显示器时自动切换采集目标（同一显卡），不同显卡则停留在原屏边缘
• 设置页「恢复默认」改为按当前子页生效、未改动时置灰；系统按键与全局热键页右上角新增「恢复默认」入口
• 修复：临时全局键（如「开始 / 暂停录制」）无法触发的问题
• 修复：录制中移动选框后，录制结果仍停留在原位置的问题
• 修复：鼠标高亮色块以指针热点为中心、偏离鼠标本体的问题

Release Notes

This update

Offline OCR (upgraded to PP-OCRv6)

• Offline text recognition upgraded to PP-OCRv6 — full-image recognition time is down to around 40 ms
• Far lower engine memory: the old engine kept hundreds of MB resident after every recognition, while the new one is smaller and returns everything as soon as a capture session ends
• Idle footprint: the graphics device and idle pages are handed back right after startup and at the end of every session — idle usage drops from 20+ MB to below 5 MB
• Fix: the OCR result panel was not destroyed when a capture session closed

Capture & saving

• Manual saving (including picking a window element) now always follows the "Manual save filename format", and the save dialog always starts on the Desktop
• Fix: "Fullscreen capture" ignored the filename format setting (it now follows "Manual save filename format")
• Fix: in the history, picking a window element was tagged as "Focused window" — now only the global "Capture focused window" shortcut does that

History

• New "Screen recording" entries: the video is not copied, only its path and a cover image are stored; the actions are Copy / Show in folder / Delete
• Long screenshots now carry their own "Long screenshot" tag; the "Focused window capture" label is shortened to "Focused window"

Other

• "Offline OCR" plugin description updated: PP-OCR latest-generation general text recognition, covering Simplified Chinese, Traditional Chinese, English, Japanese plus 46 Latin-script languages — 50 languages in total

Previous release (0.1.6)

• New "Settings → System keys": command shortcuts for capture / recording / fullscreen canvas are now rebindable, with conflict detection and fixed-key protection
• New "Appearance → Other → Shortcut hints": toolbar tooltips append the current key, and the tray menu shows the current key next to each item
• Recording: new "Selection follows cursor" and "Mouse highlight" (custom color) — the selection follows the pointer near its edges, and the cursor is overlaid with a circular highlight so viewers can locate it
• Recording: new "Exclude the system toolbar" and "Record key presses" options, plus wording updates such as "Capture save format"
• Recording: temporary global keys (start / pause recording, mouse passthrough, hide / show toolbar) now work as soon as the recording stage starts, even when another app has focus
• Recording: once recording starts the selection size is locked (handles hidden) but it can still be moved as a whole; the captured area follows the selection, and the capture target switches automatically across monitors on the same GPU (otherwise it stays at the edge of the original screen)
• "Restore defaults" in Settings now applies to the current sub-tab and is greyed out when nothing has changed; new entries added to the System keys and Global hotkeys pages
• Fix: temporary global keys such as "start / pause recording" could not be triggered
• Fix: moving the selection while recording left the captured content in its original position
• Fix: the mouse highlight circle was centred on the cursor hotspot instead of the pointer body
• Improvement: the selection is constrained to a single monitor while recording, so recordings no longer cover only half of what was framed
• Tray: the not-yet-implemented "Quick translate" item is now greyed out

Windows 10 / 11 (x64), single-file portable.

SnowAir Lite v0.1.5

更新说明

• 修复：翻译面板「正在翻译…」提示过早消失 —— 提示条改为结果落地后才收起，不再出现「提示没了、结果还没来」的空档
• 修复：在线翻译接口无响应时会一直卡住 —— 请求与响应读取增加超时，超时后自动退到下一个翻译服务
• 修复：离线翻译逐行重复加载模型、同一段话反复翻译时快时慢 —— 引擎按语言对复用，首次加载后每句仅数毫秒
• 修复：某一行翻译失败会丢弃整段结果 —— 失败行保留原文，其余行照常输出并给出提示
• 优化：多语混排（中英夹杂）按行判定方向，已是目标语言的行原样保留；整块换向增加目标语占比门限，避免误翻
• 优化：模型 / 语言包下载分阶段显示进度，并增加超时重试，避免进度长时间停滞

适用系统：Windows 10 / 11（x64），单文件免安装。

---

Release Notes

• Fix: the "Translating…" hint disappeared too early — it now stays until the result lands, removing the gap where the hint was gone but no result had appeared
• Fix: an unresponsive online translation endpoint could hang forever — requests and response reads now time out and fall back to the next service
• Fix: offline translation reloaded the model for every line, causing inconsistent speed on repeated selections — the engine is now reused per language pair (a few milliseconds per sentence after the first load)
• Fix: a single failed line discarded the whole result — failed lines now keep their original text while the rest are translated, with a notice
• Improvement: mixed-language selections are directed line by line; lines already in the target language are kept as-is, and whole-block direction switching now requires a target-language share threshold
• Improvement: model / language-pack downloads report staged progress and retry on timeout

Windows 10 / 11 (x64), single-file portable.

SnowAir Lite v0.1.4

更新说明

• 修复：截图工具栏布局保存后不生效 —— 现在截图 / 录屏 / 全屏画布 / 贴图四类工具栏都会按「外观设置」里保存的顺序与显隐生效
• 修复：马赛克上无法写文字 —— 文本工具可直接在马赛克上落笔，文字按创建顺序叠加在上层
• 修复：插件目录写死在 %AppData% —— 可用 config.json 的 common.pluginDir 自定义，或把 plugin 放在程序目录（优先程序目录）
• 修复：点托盘「设置」可能误触发截图 —— 托盘菜单改为抬起才触发；菜单打开时点击菜单外只关闭菜单，不再传给托盘图标
• 优化：点「设置」时若窗口被最小化或非焦点，会还原并聚焦设置窗口
• 新增：新版本启动时自动接管旧版本的开机自启（换了安装目录 / 升级后，自启项指向当前 exe）

适用系统：Windows 10 / 11（x64），单文件免安装。

---

Release Notes

• Fix: toolbar layout was saved but not applied — the capture / recording / fullscreen-canvas / pin toolbars now follow the order and visibility saved in Appearance settings
• Fix: could not type text on top of a mosaic — the text tool now places text directly over mosaics, stacked by creation order
• Fix: plugin directory was hard-coded to %AppData% — now configurable via common.pluginDir, or use a plugin folder next to the exe (program folder preferred)
• Fix: clicking "Settings" in the tray menu could accidentally trigger a capture — the tray menu now fires on mouse-up; clicks outside the menu only close it and are no longer forwarded to the tray icon
• Improvement: clicking "Settings" restores and focuses the settings window when it is minimized or unfocused
• New: the new version takes over the previous one's auto-start entry on launch (after moving the install folder or upgrading)

Windows 10 / 11 (x64), single-file portable.
