FileCloud 21.1 is 66% faster than the previous version, with increased efficiency and the ability to handle higher loads. System software applications have been upgraded for optimal performance on Apache, PHP, MongoDB and SOLR. Integration with Microsoft Office allows users to take advantage of one of that service’s most useful security features: sensitivity labels. Accessibility improvements mean that FileCloud is now compliant with VPAT Guideline 2.1, which requires that all functionality be available from the keyboard.
