Releases

• Aug 10, 2026 3.1.0
  A correctness and stability release. A few new reading options, much safer saving and backups, and a long list of fixes. * New: * Single Page Mode shows one page at a time regardless of the window size. * Choose the page fit policy, so pages fit by width, by height, or whole. * A Controls Hide Delay setting in Customize Controls picks how long the overlay stays visible. * When the selected text contains a link, the web search button becomes an Open Link button. * Searching now happens without leaving the document. * The first jump lands in reading history, so Jump Back returns you where you were. * The previous and next arrows wrap around at both ends in every search flow.

  * When every match is behind you the search wraps to the first one, and says so when there are none. * Double tap zoom now uses two states by default, with the old three states available in Advanced settings. * The fullscreen exit button reads Exit Fullscreen instead of Exit. * A file shared from another app now asks before copying when it is very large or space is tight. * That dialog offers keeping a copy, granting file access, or just reading it once. * Keep Copies of Shared Files becomes a choice between always keeping a copy and asking each time. * The theme toggle button stays visible when the PDF theme follows the system. * Tapping it then explains why it cannot toggle and lets you pick a theme right there. * The book title snackbar fits longer titles. * Library: * A document can no longer land in the library with an unknown page count. * A document already stored with the wrong page count is corrected the next time you open it. * Documents are identified by the hash of the first and the last MB of the file, so two files sharing a first megabyte no longer merge into one. * Files under two megabytes are identified by their whole contents. * Existing records convert quietly on open, keeping reading position and bookmarks. * Conversion is anchored to the real file, so a copy can never claim another book's history. * Home's relocate picker now heals the record even after the screen is recreated. * The reader's relocate picker verifies the picked file before repointing the record. * Backing out of that picker exits the reader again as intended. * Deleting a document now removes it correctly for every kind of file location. * Home no longer shows a stale list when two refreshes overlap. * Relinking the library no longer scans files on the screen thread. * A document with no address no longer displays the literal word null. * Saving: * Highlights made while a save is running are no longer thrown away. * Saving no longer reports success when the written file might be damaged. * The check now reads the end of the file, not just the start. * A failed save no longer retries in a way that can ruin a good file. * A spare copy is kept for password protected files too. * Saving a copy can no longer overwrite the file you are reading. * Updating a different file by mistake now asks you first. * Annotations can no longer be written to another document's chosen destination. * Saving no longer opens and re reads every highlighted page. * Saved files no longer grow with pages that did not change. * A saved file no longer balloons with a hidden copy of everything you read before saving. * Saving a file that was inflated by an older version shrinks it back to its real size. * Edits are refused politely while a save is running instead of being lost. * Deleting a document no longer races a reader that still holds unsaved highlights. * Highlights and Signatures: * Fixed highlighting in books where it silently failed. * Highlights no longer appear in a file that does not contain them. * A highlight that cannot be drawn now says so instead of pointing somewhere else. * Opening a highlight from the list centers the page counter and bookmark star correctly. * Dragging a selection handle is smoother and no longer redoes work on every touch event. * A signature no longer lands sideways on a rotated page. * Dragging a signature now moves it the way you drag it. * Reading: * Navigation History opens whenever the trail holds anything, even when every entry is ahead of you. * The page you are on is now tracked wherever the view moves, so the number in the bar is always the page you are looking at. * Jumping to a search result or a highlight now leaves you on that page, so leaving and returning brings you back to it. * Auto scroll now keeps the page number, the reading history and the saved position up to date as it goes. * Fullscreen now covers the camera cutout area instead of leaving a black band on notched phones. * Reading position is no longer erased when Always Open at First Page is on. * Right to left books no longer jump to the wrong end of the document. * Right to left books no longer save the wrong page when you leave. * Pages are centered instead of pushed to one side. * A document no longer turns a page by itself when it opens. * The first tap after opening toggles the controls instead of being swallowed. * Contents entries no longer show page 0 or jump to page 1. * Contents rows that resolve to nothing now show nothing and do nothing. * A finished one page book shows 100 percent. * Two page spreads show both page numbers when you jump. * First Page Alone shows as overridden while Single Page Mode is on. * Double tap zoom stays within your configured maximum zoom. * A drag cancelled by the system snaps the page and hides the handle. * A drag started right after a page turn is no longer ignored. * Auto scroll stops when you leave the reader and stays consistent afterwards. * Always Hide Margins now applies after you return from settings. * Rotate reads the real screen orientation, and explains itself when the system controls the window. * Rotation lock clears when you close the app. * Text Mode: * Going to a page now moves the text, not just the page number. * A page you jumped to stays put while the pages around it load. * Hyphen wrapped words read as one word. * Search boxes land on the right letters around ligatures. * Arabic search boxes use the correct character positions. * Text sizes and spacing are clamped to safe values when loaded. * Web search no longer crashes when no browser is installed. * Quote cards stay left to right for mostly English quotes. * Search: * Search next and previous can no longer freeze the screen, even in rare cases. * Repeated presses land on the right match every time. * Results are added to instead of being rebuilt from scratch. * A running search no longer holds the whole reader in memory. * Backup and Restore: * Backups keep working on Arabic and Persian phones. * Restore Pre Import Snapshot appears again after an import. * Backup cleanup keeps the newest files instead of the oldest. * An import stops safely when its snapshot cannot be found. * An import can no longer be interrupted midway by leaving the app. * The wipe warning now says that unsaved highlight recovery data and the stored signature are deleted too. * Imported settings are rejected unless they are known and correctly typed. * Two backups of the same name no longer corrupt each other on import. * The Auto Backup switch no longer reads on while nothing is scheduled. * The stalled backup notice now works for people who enabled automatic backup before it recorded a start date. * The offline dictionary no longer eats most of the system backup quota. * Backups record where a document came from, without changing the file format. * Privacy and Permissions: * Incognito stays incognito when the screen rotates while the file picker is open. * No lasting file permission is kept for a file opened in incognito. * Bookmarking a page in incognito now explains why it cannot, and offers to exit incognito. * Placing a signature in incognito no longer stores the drawn signature for later sessions. * Crash reports show the website instead of the file path. * A crash report is never sent unless you agree to it first. * Internal warnings about slow document work are no longer reported at all. * A report left over from an older version is deleted instead of sent. * A download that stops being encrypted part way asks before it continues. * A download that is not a PDF is refused instead of saved. * A download stops if it grows past a sane size or would fill the device. * Three internal screens can no longer be opened by other apps. * Android 10 and below now ask for write access as well as read access. * Copies written to public storage appear in other apps right away. * Home: * Back ends an active selection on the Folders tab instead of walking up a folder, matching the other two tabs. * Design: * Onboarding buttons no longer hide behind the three button navigation bar. * The home open button no longer collides with the navigation buttons. * The tip explaining how to leave fullscreen now actually appears, and stays gone once dismissed for good. * Release notes now appear for people who turned the Home page off. * Settings search says when nothing matched. * Renamed a label that two unrelated features were sharing. * Russian and Ukrainian delete warnings show the real count. * Clearing a single item no longer reports it in the plural, in every language. * Performance and Stability: * A page carrying an enormous amount of text now says so instead of killing the app. * Large scanned books no longer crash the reader on low memory phones. * Memory stays bounded no matter how long the book or how far you scroll. * The reader menu no longer slows the app down or pushes it toward a crash. * Fixed a rare crash while scrolling caused by preview images being reused mid draw. * Fixed a rare crash while cleaning up stored page previews. * Urgent page renders no longer get stuck behind background ones. *

drawn frame. * Opening a highlight from the list no longer looks it up twice. * Text screens no longer leak a document when closed while still opening. * Go To Page no longer leaks its window and a document. * Reopening the same reader now honors the newly opened document. * An empty reader window no longer closes the window holding your document. * Tapping a page no longer searches it for form fields. * Low memory image allocation failures no longer crash the viewer. * A failed image decode no longer loses a reusable image buffer. * A missing gesture event no longer risks a crash while flinging. * Android 6 no longer crashes on online PDFs. * Android 6 no longer crashes while installing the dictionary. * Document loading no longer reads settings off the wrong thread. * Fixed a file reading bug that could feed the app garbage. * Fixed a mismatch between two parts of the low level code. * Development: * The two native dependency build scripts merged into one. * Building PDFium
