A new property Listener is added. The document converter listener implementation is used for monitoring conversion status and progress. Have a look at ConverterListener class that implements IConverterListenerinterface

Coming to the improvement, MPP to XLS conversion is improved. Previously, there was an issue in PNG image conversion (e.g. PNG to Word or Presentation). This issue is now fixed. There was another document conversion issue, a particular Word file to PDF with exception: Could not create the bitmap with the specified parameters. This bug is also resolved.
