Fixes and improvements • Improved: the reader’s settings now have “Show annotations already in the PDF” under Annotations & handwriting. Turn it off to hide highlights and comment marks that another app saved into the PDF file itself.

Fixes and improvements • Fixed: after downloading the language data with “Download the system language” in the translation settings, translation could not be started. If the download does not finish, the app now shows where to download it in the device’s settings. • Improved: reading a paper’s structure in the background after it opens now takes much less processing.

Underline and select with Apple Pencil • The HL Pen has two new modes, Underline and Select. Underline draws a line under the text you trace (part of the one-time purchase, as highlights are). Select is free: it selects the text you trace and opens the same menu as a finger selection — translate, copy and more. To switch modes, touch and hold the HL Pen on the tool rail. Fixes and improvements • Fixed: opening the Sort menu or a “…” menu could bring up the on-screen keyboard.

Fixes and improvements • Fixed: highlights that briefly disappeared from the page — for example after switching screens — could be deleted. Handwriting was not affected. Deleted highlights can be brought back one at a time from the paper’s “…” → “Change history”. • Fixed: opening a sticky note whose handwriting had dots in it (a light tap of the pen) could freeze the app and close it. • Improved: the pen now has a fourth width, “Extra Fine”, about 40% finer than “Thin”.

Fixes and improvements • Fixed: with a different paper in each of the 2 screens, choosing “1 screen” while the right or lower paper was selected hid that paper’s highlights and handwriting and showed the other paper’s instead, and marks you added then went into the other paper. Nothing was lost: the hidden highlights and handwriting show again as before. • Fixed: an area highlight you started to move but left in place could disappear until you opened the paper again. • Fixed: touching and holding to select a word in some PDFs could freeze the app for a while, and the system could then close it. • Fixed: the app could occasionally quit as a hint or a menu appeared. • Improved: while the eye button hides your annotations, the top of the page now says “Annotations are hidden”; tap “Show” to bring them straight back.

Fixes and improvements • Fixed: after you wrote by hand in Reading Mode, the app could quit a minute or two after every launch. • Handwriting search now also finds what you write by hand in Reading Mode, on the text and on equations and figures.

Handwriting in sticky notes • Sticky notes can now hold handwriting. Choose “Write by Hand” as you place a note, or press the hand in its title bar, and the note becomes a blank sheet to write on with Apple Pencil or your finger (on a Mac, with the trackpad or mouse). Writing further down extends the sheet, and a note with handwriting opens on its sheet. Fixes and improvements • The menu over selected text on a PDF page now has “Highlight” and “Underline”, as Reading Mode’s menu does, so you can highlight with the tool rail hidden, without bringing it back. • Fixed: in some papers — Chinese papers especially, and papers with formulas inside the lines — a highlight’s band could be much taller than the line and overlap the bands of the lines above and below. It now fits the line. • Fixed: on pages with a great many strokes, the app could quit while reading the handwriting for Handwriting search. • Fixed: the reading guide’s strip could cover the page slider and the round buttons at the bottom of the screen.

Fixes and improvements • Fixed: after buying or starting the free trial, the paid features could stay locked. If you bought before this update and they are still locked, buy again with the same Apple Account: the App Store recognizes the earlier purchase and does not charge you twice. • On iPad and iPhone, Reading Mode can now show only the text: turn on “Hide buttons with the menus” in the reader's settings under Display, and the floating buttons and the page number go away with the menus. Tap the text to bring them back. • The Highlight Pen now marks only the lines its tip passes over; the lines above and below are no longer pulled in. • Fixed: selecting text in some PDFs could freeze the app for a while, and the system could then close it.

Fixes and improvements • Fixed: the app could occasionally freeze and then be closed by the system. Saving the reading state and similar records and updating the screen could end up waiting on each other. • Fixed: opening a page with a black underline could close the app.

iPhone Duo support • The app now supports iPhone Duo. On the open inner display it uses the iPad layout: the sidebar beside the list, two panes side by side, the original beside its translation. On the closed outer display it works as on an iPhone. • Half open, the divider between two panes sits on the fold and the page readout stays clear of it; closed, the Reading Mode bookmark button moves to the edge the phone opens from. The welcome screens fit the Duo’s screen height as well. Fixes and improvements • Fixed: annotations and handwriting could disappear after a paper was closed and reopened. Undoing the first annotation of a paper could silently stop all saving for that paper, and an annotation or stroke made while the paper was still loading was lost when loading finished. • Fixed: with the same paper open on both sides, one copy could save over the other and erase its additions, edits and deletions, and a stale copy could be written back when the paper was closed. • Fixed: with “Turn pages together” on in the split view, turning pages quickly on one side could pull the other side back a page. • Fixed: handwriting could be rolled back. A stroke drawn while a backup was being restored from iCloud could drop the restored pages, drawing over a restored page could erase the restored strokes on it, and a stroke after importing an archive into an open paper could bring back the pages the import had removed. • Fixed: with translation switched on but unavailable — after the trial, for example — handwriting on translated lines looked as if it had silently vanished. It is now counted and listed under “Unmatched handwriting”. • Fixed: translation of an open paper could stay on hold after the language data for translation had been added in the system settings — on returning to the app, it now checks again whether the language data is there. Also fixed: the download of the translation model could sit at 0%; if it does not start within a short while, a retry is now offered. • Fixed: in Reading Mode, on a two-column page where a figure’s label sat between the columns, the two columns could be read one line at a time, alternating left and right. • Fixed: the app could crash right after going to the background, when a hint about a button was about to appear while the app was not in front. • Fixed: the app could be closed by the system right after it went to the background. • Fixed: starting read-aloud, and overlaying the translation on the page, could freeze the screen for a moment. The character-by-character passes in text analysis and translation are lighter as well. • On iPads with less memory (4 GB or less), the app now holds less at once: the model behind related-passage search is released sooner after use, the sidebar keeps only the most recent page thumbnails, library-wide analysis waits while a paper is open, and background structure analysis runs one paper at a time. • The app’s concurrency was reviewed throughout under the Swift 6 rules, fixing races that could in rare cases garble the display or close the app: in drawing with “Darken PDF pages”, in figure cards and in the sidebar’s page thumbnails.
