UI

1. Adds progressive page rendering: Pages now show a low-resolution preview first, and then progressively refine to the full-resolution render for faster perceived load times. (J#ANDR-1704)
2. Replaces the per-page and fragment-level loading throbber with a thin Material 3 progress bar at the bottom of the page and fragment, and exposes the new LoadingIndicatorStyle as public configuration for color, track color, and height customization. Breaking: removes PdfConfiguration.Builder.loadingProgressDrawable() and PdfActivityConfiguration.Builder.loadingProgressDrawable(). (J#ANDR-1794)
3. Aligns the electronic signature tool with our iOS SDK: The signature dialog now opens immediately when the tool is activated, and the signature is placed at the center of the visible page area. (J#ANDR-1651)
4. Improves Samsung keyboard handling to prevent spaces from being swallowed after Korean text composition during content editing. (#52024)
5. Fixes fonts configured via pspdf__outlineViewStyle not being applied to the PdfOutlineView. (J#ANDR-1787)

7. Fixes a visual artifact (ghost/shadow) that appeared on annotations immediately after creation. (J#ANDR-1783)
8. Fixes annotation creation mode being exited when changing the current page via the thumbnail bar. (J#ANDR-1786)
9. Fixes double-tap word selection and long-press text selection inside a newly created free-text annotation. (J#ANDR-1796)
10. Fixes a potential IndexOutOfBoundsException during annotation selection updates. (J#ANDR-1801)

Model

1. Deprecates setMultithreadedRenderingEnabled on PdfConfiguration.Builder and PdfActivityConfiguration.Builder, along with the isMultithreadedRenderingEnabled property; multithreaded rendering is now always enabled and these options will be removed in a future version. Breaking: Removes the PdfDocumentLoader.openDocument/openDocuments/openDocumentAsync/openDocumentsAsync overloads that took a multithreadedRenderingEnabled argument — use the overloads without it. (J#ANDR-1578)
2. Renames PdfConfiguration.Builder#setFixedLowResRenderPixelCount() to setFixedFullPageRenderPixelCount() and PdfConfiguration#getFixedLowResRenderPixelCount() to getFixedFullPageRenderPixelCount() to better reflect what the value controls now that progressive rendering is in place. (#52171)
3. Fixes Multiply and Overlay blend modes rendering too dark in DeviceCMYK transparency groups. (J#CORE-1058)
4. Fixes content editing where bold or italic was only applied to part of a selection when the embedded subset font didn’t cover every selected character; fallback glyphs are now rendered in the requested weight or style instead of regular. (J#CORE-1083)
5. Fixes applying redactions producing burned overlay text that didn’t honor the configured redaction font size. (J#CORE-1078)
6. Fixes corrupted rendering of indexed JPEG2000 image tiles in clipped renders. (J#CORE-948)
7. Fixes incorrect text selection and highlighting for ligatures in some PDFs. (J#CORE-1077)
8. Fixes a SIGABRT crash on first PdfActivity/PdfFragment use when the SDK was auto-initialized without a license key. Trial mode is now activated lazily at first SDK use rather than at app launch, preserving deferred-init flows (e.g. license fetched via Firebase Remote Config). Adds a runtime warning when Nutrient.initialize is called with a key while auto-init is still enabled, recommending nutrient_automatic_initialize=false for explicit initialization. (J#ANDR-1779)

UI

1. Adds the ability to show both icons and text in popup toolbar menu items. (#51898)
2. Improves animations by unifying text selection and annotation selection animation timing. (#51788)

2. Improves performance for PDFs with large content streams. (J#CORE-1064)
3. Converts PopupToolbarMenuItem from a Java class to a Kotlin data class. (#51898)
4. Fixes a potential ANR and windowRecomposer warning when page views are composed before being attached during page injection. (J#ANDR-1777)
5. Fixes flattened annotations losing their blend mode, causing freeform highlights to appear opaque after export. (J#CORE-1065)
6. Fixes garbled text on non-redacted pages when a document uses shared font resources across pages. (J#CORE-1054)
7. Fixes a SIGABRT crash caused by the evaluation terminator when the SDK was auto-initialized without a license key. Passing a null license key no longer activates trial mode — use an empty string instead. (J#ANDR-1779)

Instant

1. Fixes a race condition where concurrent Instant attachment download completions could fail. (J#IOS-1084)

UI

1. Removes AnnotationEditingToolbar, renames AnnotationCreationToolbar to AnnotationToolbar, and merges annotation creation and editing into a single annotating mode. Full migration details — including listener changes such as replacing OnAnnotationCreationModeChangeListener and OnAnnotationEditingModeChangeListener with OnAnnotatingModeChangeListener, settings listener changes, and other controller and inspector class renames — are covered in the migration guide. (J#ANDR-1518)
2. Adds icons to the annotation popup toolbar with improved UI style and animations. (#51323)
3. Adds icons to the text selection and long-press popup toolbars. (#51373)
4. Adds touch animations to text selection handles with scale-up on press, finger tracking during drag, and smooth return animation on release. (#51632)

10. Fixes annotation selection not working after dismissing text selection in annotation creation mode. (J#ANDR-1741)
11. Fixes annotation toolbar buttons showing a toast instead of a tooltip on long press. (#51343)
12. Fixes cursor positioning when tapping in empty space to the right of a line’s text in content editing, which incorrectly placed the cursor at the beginning of the next line instead of the end of the tapped line. (J#ANDR-1757)
13. Fixes form editing mode activating when tapping an annotation that overlaps a form field. (#51484)
14. Fixes freezes when erasing ink annotations at high zoom levels by clamping eraser radius handling and sampling work. (J#ANDR-1707, J#ANDR-1743)
15. Fixes measurement scale FAB not showing when selecting a measurement annotation. (J#ANDR-1727)
16. Fixes pinch-to-zoom accidentally triggering text selection in annotation mode. (#51567)

19. Fixes the document jumping back to the first page after a content-editing save operation when the restoreLastViewedPage option is enabled. (J#ANDR-1753)
20. Fixes an issue where tapping a free text annotation to start editing would trigger drag detection and hide the keyboard and UI. (J#ANDR-1760)
21. Fixes ANRs caused by smart zoom text lookup blocking the main thread during double-tap. (J#ANDR-1762)
22. Fixes drawable providers not rendering on scrollable thumbnail bar mode. (J#ANDR-1756)
23. Fixes search highlights and annotation drawables disappearing after page recycling. (J#ANDR-1750)

4. Fixes a crash caused by ClosedByInterruptException during document opening when the IO thread is interrupted. (J#ANDR-1726)
5. Fixes a regression where adjusting the opacity slider on certain annotations didn’t correctly update the fill opacity (for example, on highlight annotations). (J#CORE-992)
6. Fixes an issue where content editing didn’t update the modification date of the PDF. (J#CORE-1032)
7. Fixes an issue where repeated redactions on certain image-based PDFs could cause the page colors to toggle or appear inverted. (J#CORE-989)
8. Fixes content editing mismatch warnings to show the original PDF font name instead of the substituted fallback font. (J#CORE-1048)

Examples

1. Improves the catalog app with clearer example categories and navigation. (J#ANDR-1748)
2. Fixes several UX issues in DocumentPagerExample: toolbar visibility during search, back button behavior, and search view placement. (J#ANDR-1762)

UI

11. Fixes the paste toolbar being dismissed immediately after appearing when long-pressing in annotation creation mode. (J#ANDR-1689)
12. Fixes two issues with the page loading view. In one case, the spinner was shown although a low-resolution rendering was already available. In the other case, the spinner wasn’t being shown when swiping to unrendered pages, resulting in just a blank page until the page image was available. (J#ANDR-1701)
13. Fixes grouped annotations (e.g. AutoCAD SHX cross marks inside checkboxes) not rendering. Annotations with an /IRT reference but a /Group reply type are now correctly treated as visible page content when using the overlay for annotation rendering. (J#ANDR-1720)
14. Fixes the FormEditingBar being hidden under the virtual keyboard in certain circumstances, as well as the immersive mode not working after an editing operation. (J#ANDR-1721)

8. Fixes render fidelity of annotations with custom appearance streams using an AP stream rendered annotation view by default unless edited or created on Android. (J#ANDR-1681)
9. Fixes some UI issues when deleting a note annotation or its replies with the note editor. (J#ANDR-1682)
10. Fixes the annotation popup toolbar not dismissing on tap. (J#ANDR-1687)
11. Fixes two issues in the page loading view: The loading spinner is no longer shown when a low-resolution render is already available, and it now correctly appears when swiping to pages that haven’t been rendered yet, preventing temporary blank pages. (J#ANDR-1701)

Model

1. Adds the ability to modify toolbar menu options while using custom activity using the OnToolbarMenuChangedListener. (J#ANDR-1686)

Instant

1. Adds additional safeguards against ALREADY_SYNCING race conditions during Instant sync retries. (J#ANDR-1662)
2. Changes autosaveEnabled in InstantPdfFragment to be now configurable, whereas previously it was forced to true.

Documents are still automatically synced every second after annotation changes. (J#ANDR-1615)
3. Removes the Instant example app. This app is poorly maintained and everything here can be achieved using the Instant example in the Catalog app. (J#ANDR-1642)
4. Fixes a potential timeout when blocking save is called from the main thread in Instant. (J#ANDR-1615)

2. Adds an Annotation#hasSamePropertiesAs(Annotation other):%20Boolean) method to check if an annotation matches visually. Note: We’ve changed the default Annotation equals operator to check the annotation’s uuid instead of its internal properties. If you need to compare internal properties on two different annotation objects, you need to use hasSamePropertiesAs. (#49039)
3. Adds the ability to configure text selection in AI Assistant chat messages via the enableTextSelection()) method. (J#ANDR-1511)
4. Adds support for preserving accessibility tags when using content editing. (J#CORE-946)
5. Improves accessibility support when working with annotations.

UI

1. Adds a PdfConfiguration option called annotationsBlockLinks, which can be set to true to block touching link annotations by using other annotations such as highlights. Previously, this was default behavior, but it doesn’t conform to the PDF spec, so the feature has been put behind the configuration option, meaning any users relying on this blocking behavior now need to set this option to true. (J#ANDR-1458)
2. Adds the OnTextFormElementSuggestionRequestListener interface, which allows display autocomplete suggestion lists for text form fields. (J#ANDR-1447)
3. Adds the ability to trigger the annotation eraser tool using the stylus button. (J#ANDR-1481)
