 # Changelog
 
+## 2025-12-15 - 2.11.0 - feat(mod_format)
+feat(mod_format): use unified diff formatter with filenames and context in BaseFormatter.displayDiff
+
+- Replaced plugins.smartdiff.formatLineDiffForConsole(...) with plugins.smartdiff.formatUnifiedDiffForConsole(...) when both before and after are present.
+- Passes originalFileName and revisedFileName as diff.path and sets context to 3 to show a unified diff with surrounding lines.
+- Improves console output for multi-line diffs by using unified diff format and including file names.
+
 ## 2025-12-15 - 2.10.0 - feat(mod_format)
 Refactor formatting modules to new BaseFormatter and implement concrete analyze/apply logic
