Hello everybody, I want to know what are the benefits when upgrading from 4.0.0 to 4.5.1? The release notes are not always explicit about the corrected bugs. Thank you very much,

Hello, I am new with Jasperreports. I successfully generated an xlsx file but when I open it, I get the following message "unreadable data". I am using JRXlsxExporter. The file size is 888Kb. I am using Jasperreports 3.7.6 and POI 3.7. I do not have this problem with JRXlsExporter. Is it possible that the problem was solved for XLS but not for XLSX? Thanks. Code:JRXlsxExporter exporterX = new JRXlsxExporter();exporterX.setParameter(JRExporterParameter.INPUT_FILE_NAME, destFileName);exporterX.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFileName.replace("jrprint", "xlsx"));exporterX.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);
