What's new

v2.3.9Nov 4, 2026

全平台 / Across platforms - 订阅页“全部标为已读”:Android、Windows 与 iOS 的订阅页菜单新增“全部标为已读”,通过同一份共享逻辑完成所有待处理更新:新章节计数清零、提醒标为已读,阅读历史、进度与时间线记录保留。 "Mark all read" on subscriptions: Android, Windows and iOS gain a "Mark all read" menu action on the subscriptions page that completes every pending update through the same shared logic: new-chapter counters reset and reminders are marked seen, while history, progress and timeline rows stay. Android - 扩展来源的下载不再被统一限速(#628):每来源 1600 ms 的请求间隔本应只作用于打开了“放慢下载”开关的来源,但只有解析器仓库读取这个开关,Mihon、Aniyomi、Legado 等仓库沿用了对所有远程来源都为真的默认值,页面请求不论线程数都被串行成每 1.6 秒一个。现在每个来源都读取自己的开关;每章下载完成后也不再多等一个最长 2 秒的心跳。 Extension downloads are no longer throttled across the board (#628): the per-source request spacing (1600 ms by default) is meant only for sources with "slow down downloads" switched on, but only parser repositories read that switch; Mihon, Aniyomi, Legado and other repositories inherited a default that is true for every remote source, so page requests ran one per 1.6 s regardless of the thread count. Every source now reads its own switch, and each chapter no longer waits up to one extra 2-second heartbeat after finishing. - 手动编辑的封面与标题不再被追踪服务覆盖(#632):以追踪服务作为元数据来源时,合并追踪元数据会丢掉用户的修改,编辑过的封面或标题被追踪服务的版本替换;现在会保留用户的修改。 Edited covers and titles survive tracking metadata (#632): while a tracking service was the metadata source, merging its metadata dropped the user's override, so an edited cover or title was replaced by the service's. The override is now kept. - 折叠屏内屏的详情页分栏(#630):详情页此前要到 1000dp 以上的展开窗口才分为简介与章节两栏,约 880dp 的折叠屏内屏虽然已是平板外壳,详情页仍是手机布局。开启宽松平板检测时,600dp 以上的中等窗口也会分栏;严格检测下竖屏平板仍保持单栏。 Split details on foldable inner screens (#630): details only split into summary and chapter panes on expanded windows (1000dp+), so foldable inner screens (~880dp) that already get the tablet shell still showed the phone layout. With relaxed tablet detection, medium windows (600dp+) split too; strict detection keeps portrait tablets single-column as before. - 章节列表可显示首页缩略图(#631):没有来源封面图的图片章节,现在可以在列表行与网格中显示该章第一页作为缩略图。开关默认关闭,位于详情页章节面板与阅读器的“更多”菜单中;来源自带的剧集图照旧显示。已下载章节直接读取本地归档;在线查询需要获取页面列表,因此按来源节流:卡片需在屏幕上停留 400 ms,每个来源同时只查一个且间隔至少 1 秒,来源返回“请求过多”时按其 Retry-After(否则 60 秒)暂停,结果在本次会话内缓存。漫画页以竖版(2:3)显示,剧集图仍为 16:9。 Optional first-page thumbnails in the chapter list (#631): image chapters without source artwork can show their first page as a thumbnail, in both list rows and the grid. The switch is off by default and lives in the more menu of the details chapter panel and the reader; source-provided episode artwork works as before. Downloaded chapters read their own archive; remote lookups fetch the page list, so they are paced per source: a card must stay on screen for 400 ms, one lookup per source at a time at least 1 s apart, and a source answering "too many requests" is left alone for its Retry-After (60 s otherwise). Results are cached for the session. Manga pages are shown portrait (2:3) while episode artwork stays 16:9. - 章节面板不再在“章节/页面”之间来回跳(#633):返回详情页后,从保存状态恢复的分页器可能与当前选中的标签不一致,两个同步逻辑每帧互相改写,面板于是不停在章节与页面标签之间切换。现在分页器只上报用户实际停留的页面,点击标签栏则直接切换。 The chapter panel stops flipping between chapters and pages (#633): after returning to details, a pager restored from saved state could disagree with the selected tab, and two sync effects then rewrote each other every frame, so the panel kept switching between the chapters and pages tabs. The pager now reports only pages the user settles on, and tab strip clicks switch directly. - 规则替换的正则也有时间上限(#627):来源规则中的替换模式(## 删除与 ##pattern##replacement)此前不受正则匹配已有的时间限制,灾难性回溯的模式可能卡住解析线程;现在同样有上限。 Regex replacements in source rules are bounded (#627): replacement patterns in source rules (## removal and ##pattern##replacement) ran without the time budget regex matching already has, so a catastrophically backtracking pattern could pin a parser thread. They are now bounded too.
