GroupDocs.Comparison for Java V26.8メジャーバージョン2026年8月8日
機能
  • PDF side-by-side comparison view: Added a new PdfCompareOptions with DisplayMode (Inline / SideBySide / Interleaved).
  • Added new SideBySideResultBuilder: Aspose side-by-side comparer, annotation grouping, page alignment (Needleman-Wunsch over per-page Jaccard similarity), blank-page insertion.
  • Added Comparer.compareSideBySide() - Lightweight path comparing only images, annotations and watermarks.
  • Side-by-side result: Page pairs are now merged into double-width pages; change rectangles are overlaid as SquareAnnotation borders.
  • Added a new PagesSetup option - compare only a page range of a PDF.
  • ChangeInfo.row / column / columnHeader is now populated for Cells comparison.
  • CSV result highlighting: Inserted runs are wrapped in (...), deleted runs are wrapped in [...].
  • JSON/text comparison is now rendered as an inline diff - one <div> per source line, <ins>/<del>/<span> runs in context.
  • CompareOptions.compareImagesPdf / imagesInheritanceMode has been deprecated in favour of PdfCompareOptions.
  • Tables are now built from Aspose's own TableAbsorber when it detects them; graphic-operator reconstruction remains the fallback.
  • TextCompareResult: Regex post-processing pipeline has been removed (extractSummaryPageText, processSpans, replaceDeletedAndAddedSpans, applyStyleToElements) - the converter now emits correct markup directly.
  • ComparisonPdfDocument private constructor no longer allocates a throwaway Document.
  • BinaryFormatter removed: Cells StylesComparer compares raw byte[] only; ComparisonHelper.objectToByteArray() has been deleted.
  • Upgraded the Aspose.Words dependency from 23.8 to 26.3 - CompositeNode.getChildNodes() need to be changed to getChildNodes(NodeType.ANY, false), Range.getFields() is now thrown.
  • Upgraded the Aspose.PDF dependency from 24.10 to 26.2 - TextState.getStrikeOut() need to be changed to isStrikeOut(); stale aspose-pdf:23.4:jdk17 pins have been removed from the parent POM.
  • Upgraded the Aspose.Slides dependency from 23.3 to 26.2 - ISlide.getThumbnail(Dimension) need to be changed to getImage(Dimension) / IImage.save(stream, format).
  • Upgraded the Aspose.CAD dependency from 23.1 to 24.6.1 - FileFormat is now a real Java enum, DWT constant set remapped.
  • Upgraded the Aspose.Imaging dependency from 23.6 to 25.12 - FileFormat.Undefined to FileFormat.Unknown.
  • Upgraded the Aspose.Cells dependency from 23.6 to 26.3 - no source changes required.
  • Upgraded the Diagram dependency from 23.6 to 25.10 - no source changes required.
  • Upgraded the Email dependency from 23.5 to 26.1 - no source changes required.
  • Upgraded the Tasks dependency from 23.1 to 25.9 - no source changes required.
  • Upgraded the PSD dependency from 21.7 to 25.10 - no source changes required.
  • Upgraded the BarCode dependency from 23.5 to 25.5 - no source changes required.
修正
  • PDF footers: A line break is now also detected on an upward Y jump (content stream emitting footer text before body).
  • Corrupted font subsets detected via Font.getBaseFont(); the RemoveUnusedFonts absorber now runs once per document instead of once per font.
  • Excel comparison: Only string cells get character-run restyling - numeric/error cells (#DIV/0!) are no longer corrupted.
  • PDF paragraph rendering rewritten: Each text segment positioned independently, with font-measured word wrap against the page width.
  • Paragraph line spacing measured top-to-top (URY-URY) instead of bottom-to-top, so it no longer includes the line's own height.
  • Table borders: Duplicate black grid over detected source borders removed; phantom white borders no longer drawn.
  • Inherited copy/paste defect in StylesComparer.processDataMethodTag - The target branch was guarded by a sourceValue null-check.
GroupDocs.Comparison for .NET V26.7メジャーバージョン2026年7月31日
機能
  • Improved HTML output for JSON files comparison.
修正

GroupDocs.Comparison for .NET V26.5メジャーバージョン2026年5月29日
機能
  • Multi-framework NuGet packaging and TFM-split packages - GroupDocs.Comparison has transitioned to a more advanced NuGet package delivery model. The main package now targets net462, net6.0, net8.0, net10.0, replacing the previous net462, netstandard2.1 targets. In addition, to reduce the download size, dedicated per-framework NuGet packages are now published alongside the main package. When installing the platform-specific package, only the binaries matching the user's target framework are downloaded - no unused platform assemblies are included.
  • PDF compare - Improved paragraph rendering accuracy in Inline mode.
  • Enhanced comparison results for PDF documents with tables.
  • Added support for optional disposal of passed stream in RevisionHandler.
  • Improved CSV comparison result readability with text markers.
  • Extended ChangeInfo with Spreadsheet Properties.
修正
  • Fixed ArgumentOutOfRangeException when comparing PDFs with styled tables.
  • Compare method throws exception for HTML output.

  • Now ships an AGENTS.md reference inside the wheel for AI coding assistants.
  • Added a new documentation page: Agents and LLM Integration (MCP server, bundled AGENTS.md, LLM-optimized docs).
  • Console script 'groupdocs-comparison' is now installed with the wheel - Includes compare, info, and list-formats subcommands.

GroupDocs.Comparison Product Family Update2026年4月1日
GroupDocs.Comparison for Java V26.3メジャーバージョン2026年3月17日
機能
  • Word-specific options are now available in a dedicated WordCompareOptions class (extends CompareOptions). Use it when comparing Word documents to configure MarkLineBreaks, CompareBookmarks, CompareVariableProperty, CompareDocumentProperty, ShowRevisions, LeaveGaps, WordTrackChanges, RevisionAuthorName, and DisplayMode (Revisions / Highlight). The same options remain on CompareOptions but are deprecated in favor of WordCompareOptions.
  • When comparing Word documents, the result Aspose Words document can be obtained via getResult().getResultDocument() even when not saving to a stream, so callers can access the comparison result document in all scenarios.
  • ComparisonMailMessage now accepts an optional FileType in the constructor. Comparer and MultiComparer pass the source/target document FileType when creating email comparison instances, improving detection and behavior when comparing email files.
  • Merging of Word paragraphs now handles null or whitespace-only text (returns 0 similarity), applies a word-count threshold for short strings (returns 10 when fewer than 4 words), and takes a snapshot of child nodes before moving them to avoid concurrent modification issues.
  • InstanceHelper.getDocument(InputStream stream, LoadOptions loadOptions, String password) has been added to load a Word document from a stream with optional load options and password.
修正
  • Fixed PNG comparison.
  • Compare class changes - AntiHackController Default, performCheck in Comparer.
  • Fixed XML declaration (Javadoc License/Metered references removed).
  • Fixed build - DiagramCompareResult isTextEmpty-getChars!=null; CodeFileTest disables.
  • Fixed build - words/format/Converter CalculateGaps package-private.
  • Comparer - Case DIFFERENT commented out; selfComparisonCheck public for tests.
  • Fixed build - ComparisonDocument constructor (Aspose.Words.Document) package-private.
  • Excel comparison hanging - Cells InstanceHelper/LoadOptions, ComparisonRange mergedCells, ComparisonWorkbook worksheets.
  • Sonar - CommonMethods.standartName null-check, StylesSetter.isHighlightColorSupported package-private.
  • Revert - ComparisonWorkbook worksheet cache, new list per call.
  • Fixed tests - MultiComparer png-UNDEFINED, else UNDEFINED-TEXT.
  • Tests - Cells StylesComparer.equals, WordSeparator.runsMerger package-private.
  • Build fix - ComparisonMailMessage(Document, FileType), Comparer/MultiComparer pass getFileType().
  • Fixes - Email FileType passed (aligned with build fix).
  • Word paragraphs merging - logic kept, merge behavior fixed.
  • Fix for Word - ICompareResult.getResultDocument(), WordsCompareResult returns _wordsDocument.
