This is a three part release. Each update builds upon the previous one. Depending on your current version of K9ERP, you may need to update just once or up to three times. In any case, if an additional update is required you will see the standard notification icon in the System Maintenance module.
Please note: File Manager is still in BETA and files are not being backed up. For more details on File Manager please see K9ERP Release 1.6.0.6.
