 # Changelog
 
+## 1.2.1
+
+- Enlarged the large PDF/XPS export dialog so every export option is fully visible.
+- Added text wrapping and window resizing for improved display scaling compatibility.
+- Tightened safe cancellation before finalizing an export, made local-backup copying
+  cancellable between files, and clarified cancellation behavior.
+
 ## 1.2.0
 
 - Improved reliability with a serialized OneNote COM worker, safe cancellation, and bounded connection recovery.
