v86 — 2026-10-29

主要改进

• 新增「减弱动画」偏好开关：偏好设置 → 外观新增「动画 / 减弱动画」（默认关闭，保持既有观感）。开启后关掉侧栏与预览栏的滑入滑出、各处淡入淡出与列表展开、侧栏目录跳转的滚动动画，以及 SyncTeX 双向跳转的高亮淡出。窗口与对话框自身的打开/关闭动画不受影响——Adw.OverlaySplitView 没有过渡时长属性，只能在同步的显隐调用期间临时关掉 gtk-enable-animations 并在返回后立即还原。

• 修复开关侧栏时的卡顿、行号慢一拍与行号短暂消失：开侧栏走 inline 动画，每帧改编辑器列宽；开着自动换行时整篇文档重排。行号滞后源于 gutter 覆盖层自身分配不变、GTK4 直接复用上一帧的 render node；行号消失源于整块重建的 surface 在绘制前就入缓存，以及重排期间按未验证的估计顶 y 平移把 surface 推出可视区。改为尺寸观察者驱动，gutter 缓存加几何指纹、覆盖守卫与「画完才发布」。顺带修掉一个静默失效的坑：GTK4 的 GtkWidget 没有 width/height 属性，connect('notify::width', ...) 不报错但永不触发，sticky scroll 与多光标原本挂的就是这样两条死连接。

• 消除输入/预览/侧栏热路径上的冗余重算与重绘：拼写检查改为按块增量重扫；预览淡出只在高亮矩形变化时标脏；页面尺寸加缓存、渲染结果改由回调投递以消除轮询唤醒；文档结构页订阅收窄到当前与根文档；侧栏统计在面板隐藏时挂起定时刷新；用户片段库按 mtime 缓存并让 revision 纳入补全缓存键；预览悬停移动不再连带重绘整页。

• 新增状态栏构建结果指示：右下角以纯文字显示根文档最近一次构建结果（如「构建成功」/「2 个错误，3 个警告」），点击打开构建日志弹窗；尚未构建过时隐藏，关闭文档时断开信号连接避免阻碍 GC。

• 补齐积压翻译：{n} error(s) / {n} warning(s) 及 v84/v85 新功能、改写后的 latexdb 宏包描述共 160 余条，在 7 种语言中全部补译；各语言未译条目降至 44 条，即语言选择器中按设计保持原语言的语言名。POTFILES 此前陈旧，顺带补进 81 个从未提取的字符串。

• Windows 便携包构建环境迁移到 MSYS2 UCRT64：MSYS2 自 2026-10 起逐步撤下 leaf 包的 MINGW64 构建，gtk4、libadwaita、gtksourceview5 等已无 mingw64 版本，构建因此切到官方建议的 UCRT64。便携包顶层目录随之由 mingw64 变为 ucrt64，启动方式变为 ucrt64\bin\setzer.bat，README 与打包文档同步更新。

• 测试：新增 20 余个无界面回归测试模块/用例覆盖上述动画偏好、gutter 缓存、滚动节流与热路径调度，并加入源码扫描守卫防止 notify::width 死连接写法回流。

Improvements

• feat: Add a "Reduce animations" preference (Preferences → Appearance, off by default). It turns off sidebar and preview sliding, crossfades, revealer expands, the sidebar list-scroll jump animation and the SyncTeX highlight fades. Window and dialog open/close animations are untouched — Adw.OverlaySplitView exposes no transition duration, so gtk-enable-animations is only flipped for the duration of the synchronous show/hide call and restored immediately.
• fix: Sidebar toggle no longer stutters, and gutter line numbers no longer lag one frame behind the text or briefly disappear. The gutter overlay was being served a stale render node, its surface cache could publish a half-drawn block, and mid-reflow offsets were estimated. Also fixes silently dead notify::width/::height connections (GTK4 widgets have no such properties) that kept sticky scroll and multi-cursor overlays from ever recomputing.
• perf: Removed redundant recomputation and repainting on typing/scrolling hot paths — incremental per-block spellchecking, preview fade only redraws on change, page-size caching with callback delivery instead of polling, narrowed structure-page and stats refresh scope, mtime-cached user snippets.
• feat: Status bar now shows the last build result of the root document as plain text and opens the build log on click.
• i18n: Translated 160+ backlog entries across all seven languages; untranslated count per language is now 44 (the language-picker autonyms, untranslated by design). POTFILES was stale and had never extracted 81 strings.
• Windows portable build moved to MSYS2 UCRT64: MSYS2 has been dropping MINGW64 builds of leaf packages since 2026-10, and gtk4, libadwaita and gtksourceview5 no longer ship a mingw64 variant, so the build now uses the recommended UCRT64 environment. The portable package's top-level directory changes from mingw64 to ucrt64; the launcher is now ucrt64\bin\setzer.bat. README and packaging docs updated accordingly.
• test: Added headless regression coverage for the animation preference, gutter cache, scroll throttling and hot-path scheduling, plus a source-scan guard against the dead notify::width pattern.

v85 — 2026-10-02

主要改进

• 修复多处运行时崩溃：本批崩溃均由新引入的静态检查流程发现，属单元测试覆盖不到的 GTK 运行路径——偏好设置快捷键捕获按下任意键即崩（缺 Gdk 导入）；构建日志行右键菜单弹出即崩（GdkRectangle 不是 PyGObject 暴露的名字，应为 Gdk.Rectangle）；取消「保存构建日志」对话框即崩（except GLib.Error 未导入 GLib）；AI 修复发送后执行阶段崩（agent_runner 为函数局部导入不跨方法共享，提升为模块级导入）。

• 修复解释器缺失弹窗无法操作：latexmk 缺失时弹窗没有任何按钮也无法可靠关闭；现两个分支共用「取消 / 前往偏好设置」响应组。

• 修复预览分段控件全灭态判断：Adw.ToggleGroup 未选中时 get_active() 返回 G_MAXUINT 而非负数，原来的 active < 0 兜底永不成立；改为按档位数判界，恒有一档亮着。

• 恢复失焦时关闭 undo 分组：document controller 中 _on_focus_leave 被后置的空占位实现静默覆盖，删除占位后「切走再切回时 Ctrl+Z 不再作用于上一段连续输入」的行为恢复生效。

• 代码清理：93 个文件清理未使用导入与未用局部变量；测试中行内 open() 改 with 语句消除 ResourceWarning，文档字符串加 r 前缀消除 SyntaxWarning；全仓库通过 ruff check 零告警。

Improvements

• fix: Preference shortcut capture no longer crashes on any keypress (missing Gdk import).
• fix: Build log crashes fixed — row context menu popup (GdkRectangle → Gdk.Rectangle), cancelling "Save log" (unimported GLib.Error), and the AI-fix execute step (agent_runner hoisted to a module-level import).
• fix: Interpreter-missing dialog shares its Cancel / Go-to-Preferences responses across both branches; the latexmk branch previously produced a buttonless dialog that could not reliably be closed.
• fix: Preview segmented control now handles the "no active toggle" state (G_MAXUINT, not negative) by falling back per toggle count.
• fix: Focus-leave closes the undo group again (an empty stub overriding the real implementation was removed).
• refactor: Removed unused imports and locals across 93 files; tests use with-open and raw docstrings (no more ResourceWarning/SyntaxWarning); the repo passes ruff check with zero warnings.

v84 — 2026-09-28

主要改进

• 新增 TikZ 片段实时预览：预览面板新增「片段预览」模式，实时渲染选中的 TikZ 代码；整篇 PDF 预览与片段预览通过工具栏分段控件一键切换。

• 新增数学公式悬停预览：在编辑器中悬停数学公式即可看到渲染预览，并修复了悬停时的闪烁、改用同心圆角并以 2 倍清晰度显示。

• 新增 chktex 实时 lint 集成：编辑时实时检查 LaTeX 常见语法与排版问题，即时提示。

• 新增智能引号与上下标自动花括号：输入引号、上下标时自动补全/包裹花括号，减少手误。

• 新增固定/取消固定文档标签页：可固定常用文档标签页，便于在多文档间切换时保持常用文件常驻。

• 新增标签页未使用/重复 label 检查：侧栏可检测文档中未引用或重复的 \label，帮助清理。

• 预览与侧栏面板切换统一为分段控件：预览/帮助两工具栏与侧栏 Document Structure / Symbols 面板切换，全面改用 libadwaita Adw.ToggleGroup 图标档位（当前档高亮、单击直达），移除原先「图标显示目标面板」的互斥单按钮；默认侧栏面板改为 Document Structure。

• Fit to Width 按钮按下态：预览 fit_to_width 模式下该按钮显示按下态，状态更直观。

• 修复点击 PDF 目录跳到下一页：修正 PDF 目录跳转目标偏移一页的问题。

• 修复行号列顶部细亮条：消除行号列顶部未绘制的细亮条瑕疵。

• 构建系统回退提示：latexmk 缺失时自动回退构建并给出针对性提示，便于排查环境。

• 图标与资源精简：替换多处按钮图标、精简 SVG 资源并调整渐变透明度。

• 翻译与 About 完善：include-bibtex 样式选择改用分段控件（样式名明确不翻译）；About 页面补全贡献者署名并修复 po 数据损坏。

Improvements

• feat: TikZ snippet live preview in the preview panel, switchable with full-PDF preview via a segmented control.
• feat: Math formula hover preview in the editor (flicker-free, concentric rounded corners, 2× display).
• feat: Real-time chktex lint integration while editing.
• feat: Smart quotes and automatic braces around sub/superscripts.
• feat: Pin/unpin document tabs.
• feat: Detect unused or duplicate \label entries in the sidebar.
• refactor: Unified preview/help and sidebar panel switching onto libadwaita Adw.ToggleGroup segmented controls (active state highlighted, one-click navigation), replacing the old mutually-exclusive single button; default sidebar page is now Document Structure.
• feat: Fit to Width button shows a pressed state in fit_to_width mode.
• fix: PDF table-of-contents links jumping to the next page.
• fix: Thin bright line at the top of the line-number gutter.
• fix: Build system falls back gracefully with a targeted hint when latexmk is missing.
• style: Replaced several button icons, trimmed SVG assets, adjusted gradient opacity.
• i18n: Include-BibTeX style selection moved to a segmented control (style names explicitly untranslated); About page contributor credits completed and corrupted po data fixed.

NeoSetzer 83

v83 — 2026-09-18

主要改进

• 全语言翻译补全至事实上的 100%：zh_CN（43 条）、zh_TW 与 de/es/fr/it/pt_BR（各 57 条）补全 v82 引入却遗漏翻译的字符串，覆盖 appdata 元数据与 fork 更新日志（23 条）、LaTeX 宏包描述（general.xml 片段如 amsfonts/braket/geometry，19 条）、AI 报错与设置文案以及整应用缩放（14 条）三类；\url{..} 的双反斜杠变体一并补译。各语言用词跟随该语言 po 既有术语风格（如 zh_TW 的「偏好設定/建置/重設」、pt_BR 的 Preferências、it 的 Impostazioni），44 条语言名 autonym 按设计保持原语言不译。

• 应用图标书页边缘接缝修复：修正 data/org.cvfosammmm.Setzer.svg 中书页边缘出现的浅色接缝，图标在小尺寸与深色背景下过渡更平滑。

Improvements

• i18n: Filled in the strings introduced by v82 that had been left untranslated — zh_CN gained 43 entries and zh_TW plus de/es/fr/it/pt_BR 57 each — covering appdata metadata and the fork changelog (23), LaTeX package descriptions from general.xml such as amsfonts/braket/geometry (19), and AI error/settings text along with app-level zoom strings (14). The double-backslash \url{..} variant was translated as well. Wording follows each language's existing po terminology (e.g. zh_TW's 偏好設定/建置/重設, pt_BR's Preferências, it's Impostazioni); the 44 language-name autonyms stay untranslated by design, so all 7 languages are now effectively at 100%.

• fix: Removed the light seam along the page edges of the application icon (data/org.cvfosammmm.Setzer.svg), so it blends cleanly at small sizes and on dark backgrounds.

v82 — 2026-09-17

主要改进

• 应用级界面缩放（Ctrl+加/减/0）：三个快捷键由「仅缩放编辑器字号」升级为整个应用界面缩放，走 gtk-xft-dpi（与 GNOME 文本缩放同源机制），菜单、标签、按钮、编辑器等全部文字随动，跨重启持久化；新增离散阶梯纯逻辑模块（1.1^k，约 51%–236%，in/out 索引互逆，杜绝浮点漂移）与恰好 100% 时不触碰系统设置的接管语义。图标与编辑器字号同步随动：新增 helpers/zoom_css.py 按倍率生成镜像样式表（穷举 libadwaita/libgtk 全部 -gtk-icon-size 字面值，运行时自动抽取自研样式），帮助页 WebKit 注入样式同步乘入倍率；编辑器字号缩放保留给 Ctrl+滚轮，与应用缩放两轴正交可叠加。另为 UIZoomManager 增加惰性自举机制，修复入口脚本陈旧时缩放功能静默失效。

• 全新应用图标与符号图标体系：应用图标更换为更贴合应用定位的书籍造型新设计（整体缩放到 93% 并保持 128×128 画布尺寸）；新增按 HIG 自主图标提炼的 16×16 org.cvfosammmm.Setzer-symbolic.svg（圆盘 + 菱形镂空 + 后方方块，支持主题着色），欢迎页空状态图标随之更换。

• SyncTeX 反向同步跳转对齐视口居中：按住 Ctrl 从 PDF 点回源码时，目标行由「最小可见化滚动」改为垂直居中对齐，跳转位置更醒目（文档首尾由 Gtk 自动夹紧）。

• 稳定性与内存优化：修复文档统计侧栏空闲时持续刷新的循环；构建完成后延迟 3 秒调用 malloc_trim 归还 glibc 空闲页，解决构建后 RSS 居高不下；预览侧栏动画期间保留旧纹理作占位、新尺寸渲染完成后再替换，消除白屏；子进程输出解码改为 UTF-8 → 系统 preferred encoding → errors='replace' 三级容错，修复中文 Windows 上 SyncTeX 出错走 cp936 代码页导致的后台线程崩溃。

• AI Fix 错误提示与工具选择修复：拆分「未配置 executable」与「系统上不可用」两类错误提示并分别指引去 Preferences 配置或检查 PATH；新增 resolve_tool_config 共享工具选择逻辑（优先 active tool，不可用时自动挑选首个可探测工具），修复第一个工具不可用时仍被选中、组装完 prompt 才报错的问题，标题栏终端按钮与 Build Log 入口同步受益。

• 翻译质量与语言切换修复：新增 po/sync-po.sh 同步脚本（--no-fuzzy-matching 杜绝 fuzzy 错配、--check 模式接入 CI 校验），es/it 补译至 100%，修正 zh_CN 存量 fuzzy 错配与未译条目，全部 7 种语言达 100% 翻译率、零 fuzzy、零 obsolete；修复开发模式下界面语言切换不生效（locale 查找路径改为指向构建目录 po/，无需先 meson install）。

Improvements

• feat/fix: App-level UI zoom on Ctrl+Plus/Minus/0 via gtk-xft-dpi (same mechanism as GNOME text scaling): all text — menus, tabs, buttons, editor — scales together and persists across restarts. New discrete 1.1^k ladder (~51%–236%) with invertible in/out indices to eliminate float drift, and takeover semantics that leave system settings untouched at exactly 100%. Icons and editor font now follow the zoom via a generated mirror stylesheet (helpers/zoom_css.py, exhaustively covering libadwaita/libgtk -gtk-icon-size literals and auto-mirroring custom styles); the WebKit help panel multiplies the factor into its injected style sheet. Editor font zoom moves to Ctrl+wheel and stays orthogonal to app zoom. A lazy bootstrap in UIZoomManager fixes zoom silently failing with a stale entry script.

• feat/style: Brand-new book-style application icon (scaled to 93% within the 128×128 canvas) plus a new HIG-derived 16×16 symbolic app icon (disc + diamond cutout + backing square, theme-tintable); the welcome screen's empty state now uses it.

• feat: SyncTeX reverse sync (PDF → source) now centers the target line in the editor viewport instead of minimally scrolling it into view.

• fix/perf: Stop the idle refresh loop of the document-stats sidebar; call malloc_trim after builds (3 s delay) so glibc returns free pages, keeping RSS down after long compile sessions; keep the previous preview texture during sidebar resize animations to eliminate white frames; and decode build/sync subprocess output with a three-tier fallback (UTF-8 → preferred encoding → errors='replace'), fixing a background-thread crash on Chinese Windows where synctex errors arrive in cp936/GBK.

• fix: AI Fix now distinguishes "no executable configured" from "not available on this system" with targeted guidance for each, and a shared resolve_tool_config helper picks the first available agent tool instead of blindly defaulting to tools[0].

• i18n/fix: New po/sync-po.sh workflow (no-fuzzy merging, stable ordering, --check mode wired into CI) brings all 7 languages to 100% translation with zero fuzzy/obsolete entries — es and it filled in manually, zh_CN mismatched fuzzy translations corrected; dev-mode language switching now works by pointing gettext at the build directory's compiled .mo files, no install step required.

NeoSetzer 81

v81 — 2026-08-31

主要改进

• 预览面板文字选择与放大镜工具栏：预览画布新增文字拖选高亮（光标变 I-beam，拖选自动归整到 glyph 边界，复用 GTK 文本复制流程），并在画布浮层基于浮点字形框精修消除与文字的错位；工具栏新增放大镜开关（Gtk.Fixed 定位修复画布 margin 溢出，画布侧支持打开后跟随真实 PDF、编译期间保持显示上一次编译结果）。预览渲染管线同步引入 draft 低分辨率兜底：单个耗时 > 200 ms 或有更高优先级构建在飞时自动降级到 draft，单帧端到端耗时 ~1650 ms → ~120 ms。

• 多光标编辑转正与列选拖动体验收紧：多光标编辑从实验性开关移除，改用分级门控（列选拖动阈值收紧、补齐 drag-end 抖动点击兜底，回归测试覆盖取消/拖出窗口/未触发修饰键三条边界），并修复多光标模式下的快捷键与交互残留问题。

• AI 设置整合与「在终端中打开 Agent」快速入口：AI 相关设置从独立页迁移到 General 页并更名为 AI Settings（含重排各页设置分组顺序、修复重置取消路径 NameError、阻止 ComboRow 重建冲掉用户保存的 active agent tool）。主窗口标题栏新增「在终端中打开 Agent」快速入口（裸启动 AI Fix 配置的 Agent CLI，不预填 prompt，工作目录 = 活动 LaTeX 文档所在目录），welcome 模式下隐藏避免空文档误操作。

• Git 集成：行级 diff 标记与侧栏面板（cvfosammmm#216 cvfosammmm#443）：编辑器 gutter 实时显示当前文件的增删行标记，Git 侧栏面板提供仓库状态浏览，配合已有的提交流程形成完整回路；偏好页 Git 面板 subtitle 裸 & 改为 Pango 实体 &，翻译文件同步更新（git 信任对话框 msgstr 结尾换行对齐）。

• 标签页 / 工作区关闭协议回归与编辑器稳定性收尾：关闭协议增加视图成员检测与 TabView page_belongs_to_this_view 契约修复，幽灵标签页与 Adwaita-CRITICAL 警告消除；未保存标签页的 Cancel/Esc 不会再误关；标题栏预览按钮跟随面板真实状态；旧 worker 被新构建取代后不再继续执行残留任务；搜索 Replace 按钮判定统一由 _current_match 提供并适配 GtkSource SearchContext 四元组返回值；预览期间避免文字选择高亮与文字错位。

Improvements

• feat: Preview canvas gains native text selection (I-beam cursor, drag-to-select snapped to glyph rectangles, GTK copy on highlight) and the canvas overlay is repositioned via Gtk.Fixed to stop margin overflow. The preview toolbar now has a magnifier toggle; the canvas keeps showing the previous build while a new compile is running. The render pipeline adds a draft low-resolution fallback — frames slower than 200 ms or with a higher-priority build in flight automatically downgrade to draft, taking end-to-end per-frame from ~1650 ms down to ~120 ms.

• feat/refactor: Multi-cursor editing is promoted out of the experimental gate into a tiered-gating default. The column-select drag threshold is tightened, a drag-end jitter-click fallback is added, and regression coverage now includes cancel / drag-out-of-window / missing-modifier edge cases. Latent shortcut and interaction glitches in multi-cursor mode are fixed.

• feat/refactor/fix: AI settings move from a dedicated page into General under the new name "AI Settings"; preference group order is rebalanced across all pages, the reset-cancel NameError is fixed, and ComboRow rebuilds no longer wipe the user's saved active agent tool. A new "Open AI agent in terminal" entry appears in the main headerbar (bare-launch of the AI-Fix-configured agent CLI with no pre-filled prompt, working directory = active LaTeX document), and is hidden on the welcome page so an empty document can't trigger it.

• feat/fix/i18n: Git integration adds per-line diff markers in the editor gutter and a sidebar repository panel, completing the loop with the existing commit flow alongside cvfosammmm#216 / cvfosammmm#443. The Git preferences panel's subtitle now escapes a bare & as Pango entity &; the trust-dialog msgstr trailing newlines are aligned, and translation files are refreshed.

• fix: The tab-close protocol grows view-membership detection plus the page_belongs_to_this_view TabView contract fix, killing ghost tabs and the Adwaita-CRITICAL warnings. Cancel/Esc on unsaved tabs no longer accidentally dismisses them; the headerbar preview button now follows the panel's real state; superseded build workers stop running leftover tasks. The search Replace button is sourced from _current_match and adapted to GtkSource's 4-tuple SearchContext return; text-selection overlays in the preview no longer drift off the glyphs.

v77 — 2026-08-21

主要改进

• 新增 LaTeX 实时拼写检查与词表管理：支持防抖式实时检查、拼写错误波浪线提示、替换建议、会话忽略和用户词典持久化；能够识别 LaTeX 命令、数学环境、引用与路径，避免误报。
• 新增插入图片对话框：支持从文件或剪贴板插入图片，保存常用设置，并为关键控件补充工具提示。
• 优化编辑器滚动、行号栏与粘性滚动：以 FrameClock 驱动惯性滚动；改进行号栏离屏缓存、HiDPI/分数缩放下的文字与图标清晰度，以及粘性滚动的行高和绘制一致性。
• 修复构建、同步与文档处理稳定性问题：修复正向/反向同步与构建中止冲突、非 LaTeX 文档导致的属性错误和构建挂起，以及文本编辑后的迭代器失效问题。
• 改善常用交互与界面细节：打开文件时默认定位到当前活动文档目录；优化自动补全背景、预览菜单、搜索展开图标和光标滚动行为。
• 建立跨平台打包与发布支持：新增 Debian、Windows x64 和 macOS Apple Silicon 自动打包；Windows 与 macOS 包内置 Adwaita symbolic 图标主题，保证非 GNOME 平台上的图标一致性；同时加入持续集成测试。
