The release has been published. <strong>May 28, 2026<\/strong>. The project is licensed under GPL-3.0, supports Linux, Windows, and macOS, and is designed for cataloging, reading, converting, and editing e-books, working with reading devices, and downloading news in e-book format.<\/p>\n<p>The main focus in Calibre 9.9.0 is not on major interface changes, but rather on improving search functionality, metadata handling, page counting, and fixing bugs in the viewer and Linux builds.<\/p>\n<h3>What\u2019s Changed<\/h3>\n<ul>\n<li>\n<p><strong>Saving searches when switching virtual libraries.<\/strong><br \/>\nA new option has been added to the search settings, allowing users to save the current search string when switching between Virtual libraries. This feature is useful for large collections where users categorize books into logical groups but want to apply the same filter to different virtual libraries.<\/p>\n<\/li>\n<li>\n<p><strong>More accurate page counting for fixed-layout EPUB.<\/strong><br \/>\nThe Pages column can now count pages more accurately in EPUB files with fixed layouts. Such books behave more like PDFs: their pages are pre-defined, so standard text volume estimation methods may yield inaccurate results.<\/p>\n<\/li>\n<li>\n<p><strong>Improved book addition functionality by ISBN.<\/strong><br \/>\nWhen adding by ISBN, Calibre now ignores spaces around the colon that separates the identifier type from the value. This small but useful fix is helpful for cases where identifiers are copied from external sources with extra spaces.<\/p>\n<\/li>\n<li>\n<p><strong>The WolneLektury store in the Get books section has been updated.<\/strong><br \/>\nThe built-in search and purchasing\/obtaining mechanism for books through 'Get books' has been updated for the WolneLektury store. This should improve the experience with the corresponding book source.<\/p>\n<\/li>\n<li>\n<p><strong>Fixed search in the e-book viewer.<\/strong><br \/>\nIn the E-book viewer, a bug with incorrect match offsets in standard search mode has been fixed, particularly if the text contains Unicode characters outside the Basic Multilingual Plane, i.e., non-BMP characters. Practically, this could lead to incorrect highlighting of found text.<\/p>\n<\/li>\n<li>\n<p><strong>The content server now applies empty metadata more accurately.<\/strong><br \/>\nWhen issuing book files through the built-in <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/\" title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a> Calibre content now applies null metadata just like the save-to-disk function does. This aligns the behavior of different book export methods.<\/p>\n<\/li>\n<li>\n<p><strong>Fixed download issues. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/ssl-sertifikat\/\" title=\"SSL\" data-wpil-keyword-link=\"linked\">SSL<\/a>-certificates in Linux on Fedora 44.<\/strong><br \/>\nThe issue preventing SSL certificate loading on Fedora 44 has been resolved in the Linux builds. This may have impacted Calibre's network functions, including fetching metadata, working with online sources, and downloading news.<\/p>\n<\/li>\n<li>\n<p><strong>Backspace input in the bulk metadata editing window has been fixed.<\/strong><br \/>\nIn the Bulk Metadata dialog, the situation where the Backspace key did not work in numeric fields when the value was set to Undefined has been corrected.<\/p>\n<\/li>\n<li>\n<p><strong>New news sources have been added.<\/strong><br \/>\nCalibre 9.9.0 introduces various Hungarian and Czech news sources from bubak, as well as SuperInteressante from Pedro Henrique Souza.<\/p>\n<\/li>\n<li>\n<p><strong>News sources have been updated.<\/strong><br \/>\nSources for Indian Express, Business Standard, BBC, New Criterion, Associated Press, ProPublica, LA Times, Washington Post, New Yorker, TLS Magazine, Asian Review of Books, VOX, The Conversation, Chicago Tribune, New Republic Magazine, and TIME Magazine have been updated.<\/p>\n<\/li>\n<\/ul>\n<p>For Linux <a rel=\"nofollow\" href=\"https:\/\/Calibre-ebook.com\/download_linux\">on the official download page<\/a> version is available <strong>9.9.0<\/strong>, while developers still recommend using the official Calibre binary installer rather than packages from distribution repositories, which may lag behind or contain distribution changes.<\/p>\n<p>Source: <a rel=\"nofollow\" href=\"https:\/\/www.linux.org.ru\/news\/opensource\/18305401\">linux.org.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0412\u044b\u0448\u0435\u043b Calibre 9.9.0 \u2014 \u043d\u043e\u0432\u044b\u0439 \u0432\u044b\u043f\u0443\u0441\u043a \u0441\u0432\u043e\u0431\u043e\u0434\u043d\u043e\u0433\u043e \u043c\u0435\u043d\u0435\u0434\u0436\u0435\u0440\u0430 \u044d\u043b\u0435\u043a\u0442\u0440\u043e\u043d\u043d\u044b\u0445 \u043a\u043d\u0438\u0433. \u0420\u0435\u043b\u0438\u0437 \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d 28 \u043c\u0430\u044f 2026 \u0433\u043e\u0434\u0430. \u041f\u0440\u043e\u0435\u043a\u0442 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u0442\u0441\u044f \u043f\u043e\u0434 GPL-3.0, \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u0438\u0432\u0430\u0435\u0442 Linux, Windows \u0438 macOS \u0438 \u043f\u0440\u0435\u0434\u043d\u0430\u0437\u043d\u0430\u0447\u0435\u043d \u0434\u043b\u044f \u043a\u0430\u0442\u0430\u043b\u043e\u0433\u0438\u0437\u0430\u0446\u0438\u0438, \u0447\u0442\u0435\u043d\u0438\u044f, \u043a\u043e\u043d\u0432\u0435\u0440\u0442\u0430\u0446\u0438\u0438, \u0440\u0435\u0434\u0430\u043a\u0442\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f \u044d\u043b\u0435\u043a\u0442\u0440\u043e\u043d\u043d\u044b\u0445 \u043a\u043d\u0438\u0433, \u0440\u0430\u0431\u043e\u0442\u044b \u0441 \u0443\u0441\u0442\u0440\u043e\u0439\u0441\u0442\u0432\u0430\u043c\u0438 \u0434\u043b\u044f \u0447\u0442\u0435\u043d\u0438\u044f \u0438 \u0437\u0430\u0433\u0440\u0443\u0437\u043a\u0438 \u043d\u043e\u0432\u043e\u0441\u0442\u0435\u0439 \u0432 \u0432\u0438\u0434\u0435 e-book. \u041e\u0441\u043d\u043e\u0432\u043d\u043e\u0439 \u0443\u043f\u043e\u0440 \u0432 Calibre 9.9.0 \u0441\u0434\u0435\u043b\u0430\u043d \u043d\u0435 \u043d\u0430 \u043a\u0440\u0443\u043f\u043d\u044b\u0435 \u0438\u043d\u0442\u0435\u0440\u0444\u0435\u0439\u0441\u043d\u044b\u0435 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":8,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-181802","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 -
