Major Features

Ability to specify ChangeType directly in the GetChanges method

You can now specify ChangeType directly when calling the GetChanges method to filter which types of changes are returned.

New WordCompareOptions class for Word document comparison

A new WordCompareOptions class has been created specifically for Word document comparison, allowing you to configure Word-specific compare options in a dedicated, type-safe manner.

using (var comparer = new Comparer("source.docx"))
{
    comparer.Add("target.docx");

    var options = new WordCompareOptions()
    {
        DetectStyleChanges = true,
        DisplayMode = WordCompareOptions.ComparisonDisplayMode.Revisions
    };

    comparer.Compare("result.docx", options);
}

Public API changes

CompareOptions has been refactored to separate document-type-specific settings. Word-specific options are now available in the dedicated WordCompareOptions class (DisplayMode, MarkLineBreaks, CompareBookmarks, and others). These properties remain on CompareOptions but are marked as obsolete and will be removed in a future release. Existing code remains backward compatible.
