v10.0.0

What's New in 10.0.0

Image Optimization

• optimizeImages() — lossless PNG re-compression at zlib level 9 with metadata stripping, and BMP-to-PNG conversion (typically 10-50x size reduction). Zero external dependencies.

Document Sanitization: clearDirectSpacingForStyles()

• Removes direct w:spacing overrides from paragraphs whose style already defines spacing, so style-based spacing takes effect. Protects w:pPrChange and w:rPr blocks.

Run Property Change Tracking API

• getPropertyChangeRevision(), setPropertyChangeRevision(), clearPropertyChangeRevision(), hasPropertyChangeRevision() — direct access to w:rPrChange on runs
• Automatic rPrChange creation when run formatting changes with tracking enabled
• Merge support for existing property changes

Run Formatting Cleanup

• clearMatchingFormatting(styleFormatting) — removes direct formatting that matches a style definition, enabling style inheritance

Paragraph

• clearSpacing() — removes direct spacing so the paragraph inherits from its style

Normal/NormalWeb Style Linking

• applyStyles() now links Normal and NormalWeb styles by default (linkNormalWebToNormal: true)
• Preservation flags: preserveWhiteFont, preserveBold, preserveCenterAlignment

Other Improvements

• ImageManager.updateEntryFilename() for format conversion workflows
• NumberingManager.markAbstractNumberingModified() for direct level modifications
• TrackingContext.createInsertion()/createDeletion() factory methods (eliminates circular dependencies)
• Save state rollback now restores post-processing flags on failure
• centerLargeImages() clears direct indentation before centering
• applyStyles() caps ListParagraph hanging indent to left indent

Statistics

• 128 test suites, 2,819 tests passing
• 121 source files
• 3 new test files, 67 new tests
